[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se

[Jobo]

A quick report on my experience with kernel 2.6.32-26:

First, installing this kernel version appeared to overwrite the Realtek-
supplied driver (see #54 above, second-to-last paragraph), but the
driver supplied with the kernel suffered from the same flaws as the
driver supplied with 2.6.32-25. This was fixed by uninstalling and then
reinstalling the package created with checkinstall, but the Realtek-
supplied driver didn't work as well with kernel -26 as it did with -25:
Didn't detect as many networks, signal not as strong, system freezes. I
just set grub to boot to -25 by default, and this seems to fix the
problems.

Just reporting back: Only problem in nine days was one random
disconnect, so I consider my problem fixed... phew!

@dmbfan2007: If you're still having problems, and you're using 32-bit, I
would suggest trying the ndiswrapper route. It is fairly straightforward
and easily reversible.

1. Download the Windows XP 32-bit drivers from Realtek's web site: 
.
2. Install ndisgtk. At the command line, type "sudo apt-get install ndisgtk" 
(without the quotes, here and in what follows).
3. Add ndiswrapper to /etc/modules. At the command line, type "gksudo gedit 
/etc/modules". This will bring up /etc/modules in the text editor. Add a line 
at the end with the single word "ndiswrapper" (no quotes). Save and quit.
4. Figure out what Linux driver you're using. At the command line, type "lsmod 
| grep 819". You should see a line that says something like "r8192se_pci
5121840", except in your case it will probably be "r8191se_pci" or 
something like that.
5. Blacklist the Linux driver in /etc/modprobe.d/blacklist.conf. At the command 
line, type "gksudo gedit /etc/modprobe.d/blacklist.conf". Add a line at the end 
that says "blacklist r8191se_pci" (no quotes), replacing r8191se_pci with 
whatever driver you are using.
6. Follow the instructions here 
 at 3.3 and 
3.4.1 to extract the Windows driver from what you downloaded and install it 
using ndisgtk.
7. Restart, throwing salt over shoulder, knocking on wood, keeping fingers 
crossed, and the like.

If it doesn't work, you can undo everything step by step: Uninstall the
driver in ndisgtk, unblacklist the Linux driver by deleting the line in
blacklist.conf, remove ndiswrapper from modules, and if you like
uninstall ndiswrapper. After restarting, you should be back exactly
where you are now.

@dmbfan2007
If you happen to have the source code, just follow the instructions provided by 
realtek to me:

>Dear Sir / Madam,
>
>Thanks for your mail.
>Please find the latest RTL8191SE Linux driver source in the attachment.
>You should clear previous drive or inbox driver first after you install this
>driver source.
>The previous driver will be stored within
>/lib/modules/2.6.XXX/kernel/driver/staging.
>Please remove "r8192se_pci.ko" files by following command.
>1. sudo su (you should input you root password after it)
>2. find /lib/modules/ -name "r8192se_*.ko" -exec ls -l {} \; 
>3. find /lib/modules/ -name "r8192se_*.ko" -exec rm {} \;
> 
>After, You could execute "find /lib/modules/ -name "r8192se_*.ko" -exec ls
>-l {} \;" to confirm it's clear properly.
>And then, install this driver source as below steps. Don't forget to extract
>this package before you install it.
>1. sudo su
>2. make
>3. make install
>4. reboot
>5. ./wlan0up or ./wlan1up

Then, to reset when needed, i simply made a button to shut it down and
start it up again.

>./wlan0down
>./wlan0up

Put that in a file, chmod +x it, then put a shortcut wherever you want
it and have the shortcut gksu the file that uses the down and up
scripts. Then click, enter password, and it resets.

@Jobo
Thanks for your documentation.  I have the rtl819xSE using a rtl8191SEvB and am 
seeing nearly the exact same thing.  I'm not so great with moving drivers in 
and out, so I'm afraid to try half the stuff you have without breaking it all.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se

[Jobo]

I've been continuing to try to find a workaround for this problem, and I
thought I would share what I've tried, what hasn't worked, and what
seems now to be working.

First, I tried installing the lastest Linux driver from Realtek's site
(v. 2.6.0018.1025.2010) following the readme included with the download.
This involves manual installation using "sudo make" and "sudo make
install" from the command line. This did not work, and using "make
uninstall" broke my wireless completely. (Easy to see why if you look at
the makefile: Both install and uninstall go all over the place "rm
-rf"ing things, and I consider myself lucky that all I broke was the
wireless.) Finally got it "working" again, with the Lucid driver, by
uninstalling and reinstalling the kernel in Synaptic, and manually
copying the firmware files from the download to /lib/firmware/RTL8192SE.
Random freezes, however, persisted.

Second, I tried installing the WinXP driver (v. 1092.1.0802.2010) using
ndisgtk. By blacklisting the Lucid kernel module (rtl8192se_pci) in
/etc/modprobe.d/blacklist.conf and including ndiswrapper in
/etc/modules, I was able to get ndiswrapper to load and install the XP
driver. But this didn't work at all, and "sudo lshw -C Network" showed
that no driver was associated with the card. Searching /var/log/syslog
for "ndiswrapper" showed that it was unable to load the XP driver
because of a couple of "unknown symbol" errors. The Windows 7 driver
produced a similar result. Basically, the Windows drivers appeared not
to be compatible with ndiswrapper.

I subsequently discovered that the 32-bit XP drivers may in fact work
with ndiswrapper, but the 64-bit drivers (which is what I use) are known
not to work. So you 32-bitters may be able to go this route, if
necessary.

Finally, I tried installing the Realtek Linux driver (version above)
using the modified procedure of "sudo make" followed by "sudo
checkinstall." (Checkinstall packages the installation such that it can
be removed later using Synaptic, if needed.) This worked, in that it did
indeed install the new driver and it does now connect. I would also note
that the signal strength in my small apartment is now shown as three or
four bars, instead of one or two before. What I don't yet know is
whether it fixed the biggest problem, which was the random OS freezes. I
will report back once I have enough connects under my belt to get a
sense of that.

I still think, though, that this would benefit from a "real" solution.
This card may be hated, but it is very common, and it is frequently
installed on laptops (such as my Lenovo X201) with BIOS locks preventing
the owner from installing other wireless cards. It is possible to hack
the BIOS to get around this, but in doing so one runs the risk of
bricking one's laptop, which I am not willing to do.

[Shane]

The driver that comes with ubuntu works for a while, but i have no idea
how to restart it when it breaks down (or how to identify when it breaks
down as easily as identifying the realtek drivers breaking down). I've
discovered that overall heat affects connectivity and even direction of
the laptop in relation to the router (this tells me that there might be
a physical issue as well). I've even caught it blocking access of one
wireless device from connecting to the router when my laptop was placed
between the two, while, interestingly enough, the laptop actually kept a
stable connection. Restarting the drivers almost always works, however
it is annoying. The default driver, while it now works to some degree,
does not last forever (but it does work longer than the realtek driver).
I've found that locking my router to a specific channel also helps
(beware overlaps, though) in the range department. This card is livable,
but it's rather annoying and i still can't rely on the connectivity to
fulfill my needs. I'm sure, though, we could easily create a script to
restart it for us automatically (even then it's not guaranteed to work).
All i can say is, if you have it, consider direction and position until
it connects, then move around as you see fit until it's time to
reconnect again.

Also, make sure you recommend against realtek in the future, as their
product clearly doesn't meet our needs.

  my problems seem to have been solved but even so I would recommend to 
ubuntu users that they replace any realtek wifi cards rather than deal 
with this -- on many laptops this is not as hard as it sounds.  It would 
be nice if this chipset is also listed in a compatibility database 
somewhere as linux-incompatible...

[JL]

The problem is still here for me running any version of this driver
either from Ubuntu or Realtek themselves. I have even tried emailing
their tech support for help and the drivers they sent me still cause the
same problems, some even worse than before. For me even if I am not
connected to anything just have the driver installed I get the hard lock
up and have to do a hard reboot and then restart again to get everything
going correctly again. I have to resort to using a USB dongle for wifi
and leaving the driver out of the system. Funny thing is my USB adapter
is a realtek as well just different chip version and it rocks no issues
at all. I am on a toshiba x505-887 running Ubuntu 10.10 Kernel
2.6.35-23-generic, nvidia driver.

I have done every possible combination to confirm its this driver alone
and for my system its only this that makes it unusable.

One additional point: Once it connects, it works just fine, until/unless
it eventually freezes out of the blue. I.e., I don't experience the poor
reception, dropped connections, etc. that some other folks have
reported. --Jobo

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se

[Jobo]

Just adding my two cents here because I don't think this bug has been
fixed.

I have a Lenovo X201 (3249CTO) laptop with the Realtek 3172 (rev. 10)
card. I am running Ubuntu 10.04 with the 2.6.32-25.45 generic kernel,
and using the r8192se_pci kernel module and (per lspci) the rtl819xSE
"kernel driver in use." The only thing possibly nonstandard is that I am
using the latest version of the firmware from Realtek's web site rather
than the one that came with Lucid.

I connect almost exclusively to G networks using WPA-PSK, but I connect
manually as needed rather than having the computer set to connect
automatically. On a good day, the computer will freeze on ~30% of
connect attempts; on a bad day, it can be north of 50%. Additionally,
once or twice a week it will freeze up out of the blue. In all of these
cases, /var/log/syslog indicates that it froze while attempting to
negotiate or renegotiate with the wireless network. Also, in all of
these cases, it is a hard freeze requiring a power-off/power-on restart,
but without a kernel panic.

I'm happy to post syslog excerpts or provide any other information that
may be useful. Just wish I could actually DO something to help with
this, as it's very frustrating.

Jobo

P.S. Apologies if I stepped on anyone's toes by changing the status back
to confirmed. Please advise re etiquette if that was not the right thing
to do.

Ok couldn´t put his as a DUPLICATE so I put the #215802 as a duplicat

Please note that these other bugs are for the 8187b internal usb

Ok so Launchpad didn´t let me add this bug as a DUPLICATE, so I managed
to link our old bugs to this...

We were dealing with Realtek 8187b chipset, and the problems are mainly
with the onboard usb chip.

Please see bug #215802 for a full discussion on the subject.

Thanks all (will try the -proposed kernel to see if this is fixed - I´ll
post results in 1-2 days)

Mancy - you could also use 'rfkill unblock wifi' to achieve the same
result under Linux.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Mancy]

it Works for me.
my station: Toshiba L510 Satellite Realtek 8172 with driver RTL8192SE

I've discovered my WIFI problem with Lucid 2.6.32-24-generic

my system was in dual-boot, i logged in to windows then i was using the
LAN which led me to deactivate/disable the WLAN using the keyboard
function keys.

then all solutions on Ubuntu doesn't work, until i booted to windows
again and activated the WLAN driver then rebooted to Ubuntu and that
made it WORK.

so my suggestion is to activate your WLAN using the keyboard function
keys from Windows or other application because i cannot use the keyboard
functions keys on Ubuntu to activate or deactivate the WLAN Driver.


hope it helps ;)

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Shane]

I don't know if this is the same driver or not, but i was emailed this
driver (when i emailed Realtek) with a slightly different version number
(a more recent build or testing maybe?). By limiting my range (something
i havn't tried to do) to about 5 meters or less, i am able to maintain a
relatively stable connection for almost 24 hours. Normally my log
complains twice a minute when i leave the safe range.

This doesn't stop the syslog's ramblings, but the connection is
seemingly stable. The syslog appears to complain more often, however,
which makes me think there's alot of give and take with these drivers. I
emailed them back with a mention of the huge range issue, so we'll see
how things go from there.

[Brian Candler]

All current Macbooks are x86. You can even boot them into Windows if you
buy a copy.

As for the mini PCI: Thinkpads do generally have very good hardware
maintenance manuals that you can download from the Lenovo support site.
You'll be able to check how easy it would be to open up and swap the
miniPCI, and you can pick up a new Atheros one for $10-$20.

[BTW, my very old Thinkpad X30 was locked to a particular wireless card
vendor: it wouldn't boot with a different one installed. The workaround
was to bootup without the card, run a utility to flip a bit in the CMOS,
and then reinstall the card. Hopefully they don't do that any more]

>Not really, can you explain what you saw? How long did the transfer
take, or before it got interrupted?

Aside from seemingly random freezes in the progress bar for a split
second at a time, what you see in the log at that time is what i saw.
The transfer completed successfully.

>Possible side issue, but have you tried disabling screen blanking (xset
s 0) and disabling all other power management which might kick in N
minutes after you last touched the machine?

The first thing i did was removed the default power manager (because it
has always been a problem for me on my previous laptop where it'd go
critically low battery on plugin) and installed kpowermanager and turned
off all the power save stuff except "Prefer power savings over
performance" on battery (option not available when plugged in, but i
have had the issue come up while plugged in too, so i doubt that option
is the culprit). I did this because this new laptop is like the old
laptop in that it has an ati card. My last laptop would have major
issues with power save functions and that ati card not returning from a
power save mode (actually, it ended up freezing the computer because i
could not ssh in).

>Also, you could try removing the battery and running just on mains, so
that you don't get any ACPI events like "battery fully charged". My
Thinkpad X100e has strange lockups in these circumstances.

Considering these never happen during those times and i've often since
restarted the driver after plugging it in or unplugging it, i doubt this
is the case, however later on i will try it just to be sure.

>More likely, they care about their Windows customers but not those who

Linux a risky business.

Yeah, when i bought the thing i called my girlfriend and had her do some
serious google work while i was looking at them. She said that she found
this particular laptop as one they managed to get working using ndis or
they solved the driver issues. Turns out the laptop walmart gave me
merely looks like the one i picked out (not complaining, as i paid
500usd for what i found out to be a 700usd laptop). Consequently, this
lead to the problem I'm having right now.

>If you want a laptop with a Unix-based O/S which works out of the box,

that.

I prefer an x86 laptop (because i like to do assembly development).

>I notice Dell still have an Ubuntu page:
>http://www.dell.co.uk/ubuntu

Worse yet, my last laptop was a Dell. That thing was a horror story,
because the hardware was more compatable with ubuntu than it was with
the world. The lid specifically was obviously designed to physically
break with time (which it did, hence why i opened it up in the first
place), but i'd rather not delve into the details here, as that would be
counter productive.

>Otherwise, if the wireless is a miniPCI card, you can replace it with
one with better driver support.

More investment. I don't know what it is for sure, but it's on the
inside, not the outside, and this laptop doesn't have any external ports
except USB, HDMI, VGA, Ethernet (which surpsrisingly doesn't work) and
your standard mic and headphone jacks.

More likely, they care about their Windows customers but not those who
replace Windows with Linux, since the product was never advertised as
working with Linux in the first place. This makes buying a laptop for
Linux a risky business.

If you want a laptop with a Unix-based O/S which works out of the box,
probably your best bet is a Macbook - but you pay a large premium for
that.

I notice Dell still have an Ubuntu page:
http://www.dell.co.uk/ubuntu
but AFAICS that now links to a list of laptops with Windows and no mention of 
Ubuntu.

Otherwise, if the wireless is a miniPCI card, you can replace it with
one with better driver support.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Shane]

Just to try to speed things up to make it go into that infinite loop of
non-connectingness, i decided to transfer 2.9GB of data from my desktop
computer to my laptop, and low and behold something so incredibly
obvious appears. Right at about 1:50 is where i started the file
transfer. Want to guess when it completed? I find it so strange that
even outside of those "message repeated" errors, i could set my watch
fairly accurately to these debug messages (well, here and there they
seem to miss a minute, but still). Granted, i don't loose connection
from services (my router, however, is complaining in it's logs) at those
times (haven't had a chance to time "talking glitches" with skype yet,
but at this point i doubt i have to). If only i knew my way around those
drivers and wireless networking hardware, i'd fix the problem myself,
however I don't.

While typing this, my connection went out again. I found that before
finishing this, though, it inevitably reconnected. So i updated the file
accordingly while typing. Anyway, if not all these messages correspond
to a single issue, solving them so that they disappear would help the
issues come into light more clearly. I originally had a theory written
here on what the problem was, but once i got enough data, i realized
that connecting all these error messages was a stretch. A new theory,
though:

There's a 6 element queue of something called "TX." The driver gets
"stuck" whenever it runs out of TX (slowly, but progressively), however
it can't free TX because something (that it can't sacrifice because data
would end up permanently lost, despite it supposedly not being lost) is
using that 6th slot. Now, it'll have a little success, but inevitably
because this queue's usage grows and can't be freed at the rate in which
it gets used up, it inevitably gets truly stuck and connection is lost
and cannot be re-established. Though, my guess is that i'm actually
totally wrong, because i'm just making a wild guess on the data, but if
all else fails, it's something to go on, because solving any of these
messages could clear them up enough to see the real problem.

The only thing i really can't explain is that i did have one good night
where nothing happened in syslog for about 8 hours or why these messages
appear so consistently.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Shane]

Well, i just started having trouble with the current drivers again. It
seems the kernel driver is really crappy, and the current realtek driver
is still crappy, but not as crappy. I used skype to help with this. No
one can hear me on skype if i use the kernel driver (apparently my
instructions above did not work, as it seems it still enables the kernel
driver anyway), so if i disable that and use the wlan0up i am still
heard, but after so much network usage, it'll eventually crash and burn
again (and no, this wasn't just skype disconnecting, but everything)
into an infinite loop of failed reconnect attempts inevitably reasking
for my simple WEP key. I just got this new laptop (toshiba satellite
L654D-S4025) after dealing with a crappy dell vostro 1000 that i swear
was rigged to fall apart (and i took the thing apart and could put it
back together again, but i still could not see the logic behind alot of
component placements and so forth that just seem so counter intuitive),
so i'm starting to ask myself whether or not i should even bother with
laptops anymore. i'm seriously sick of companies not caring whether or
not their product works.

Doing some research on this particular card here at launchpad, it seems
to be a common assumption (and i agree with it) that Realtek just
doesn't care about making their product work (understandable, they make
too much money off of people simply buying new components rather than
making old ones work). I also have another really weird issue (i don't
even know how to report it let alone who to report it to) with this
laptop that i can't solve.

Maybe i'm doing something wrong. I hope so: i hope i'm wrong. I want
this to be a quick and simple issue to fix so that i don't have to
constantly run some sort of wlan restart script every time the driver
decides it wants to go nuts on me. I'm gonna keep testing until i can
figure out what i'm doing wrong.

Shane >> I was experiencing those frequent kernel messages too since 2.6.0017 
version of Realtek Drivers.
So I decided to switch back to 2.6.0014... and everything seems to work fine 
until now.
I guess there recently has been some changes in rtl8192 in linux staging 
area...so there must have been some conflicts after the upgrade to 2.6.32-23.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Shane]

elPraga, thanks to you pointing that out, i managed to get my driver
working a little better. I'm running the 2.6.32-23-generic kernel, but
it seems to me that that kernel module is still semi-broken. (connection
has issues after an hour with that annoying crash requiring startup.
According to syslog and various other tools, i've kept a good stable
connection for a whole 8 hours (impressive at this point) with only a
silent disconnect that none of the networking programs i use (like irssi
and such) even noticed. I'd post a syslog to go with it to show the
difference, but apparently they're getting deleted every day (or hidden
somewhere). I gotta find a way to keep those logs available for longer
periods of time... But that's for another topic.

So yes, if you're reading this (thank god you found this one and not
another one), simply (i'm putting the instructions here for completeness
sake and for ease of those who don't know how to use all those fancy
unix commands):

sudo su #yes, this is necessary
rmmod r8192se_pci #blacklist it, too in /etc/modprob.d/blacklist.conf
cd Downloads/rtl8192se_linux_2.6.0017.0507.2010 #if this line fails, change it 
accordingly to the one you downloaded from realtek's site
make
make install
mv HAL/rtl8192r8192se_pci.ko /lib/modules/$(uname 
-r)/kernel/drivers/net/wireless/r8192se.ko
depmod -a

I'm not sure if that truly solves the problem, though, because i'm still
getting kernel messages once a minute after i do that (as opposed to
none if i use the wlan0up script), and i haven't had time to test to see
if it still disconnects or not after following those instructions. If it
doesn't work, i'll work on finding a way to make it work (hopefully not
the same solution to use a startup script obviously requiring a login
script which would thus reqire password at login to startup the wlan)
and post the complete instructions (or a fix to the current
instructions).

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[elPraga]

Hello all,
I ran into the same problem on Toshiba Satellite A 500-18Q. I found a solution 
that works quite well. 

After installing the driver as noted here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/544485?comments=all

I created a script that changes to the directory of the driver and runs the 
wlan0up script provided there and I have put it in to 
the rc.local script. It works even after upgrading kernels without 
modifications (so far :-) )

nano /usr/local/bin/wifi_workaround.sh

#!/bin/bash

cd /the_path_to_the_driver/rtl8192se_linux_2.6.0017.0507.2010

./wlan0up

chmod a+x  /usr/local/bin/wifi_workaround.sh

and add these lines to /etc/rc.local :

# The wifi error workaround..
/usr/local/bin/wifi_workaround.sh

I hope it helps someone..

Greetings.

Oh thanks, now I know another way to crash my Thinkpad X100e :-(

In return you might want to see if you can crash yours according to bug
#591699 (i.e. "xset s 1" to blank the screen while transferring a large
file over the ethernet).

I haven't yet tried repeating the test with various kernel modules
unloaded, but that might point to a problem with one of them.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Matt Price]

At least some people are reporting kernel panics with the Realtek
closed-source drivers (one here, 3 more on lp:585938).

1) can anyone subscribed to this bug test whether running powertop with the 
r8192se_pci module loaded causes a kernel panic (running in a VT at least lets 
you see the kernel panic message, so you know what's happening)?
2) anyone have any ideas how to report bugs to the Realtek upstream?
3) given that the crash is reliably caused by powertop, does anyone have 
workaround ideas (that is, what does powertop do to cause the crash, and can we 
stop whatever other processes are doing that same thing from performing that 
action?  I bet it has something to do with probing the power-saving state.  or 
something like that.  

Thanks, Matt

Just a heads up:

Version 17 of the driver is up on the realtek site.

I had to patch the makefile as usual to remove the ENABLE??? option  (I
do not remember it now!) that was described on the earlier posts.

I did not yet look at the source differences, but the changelog is quite
small...

[Vadim Chekan]

I want report success too. My box is ASUS Eee-1201T with Realtek 8192se adapter 
(discussed in some duplicate threads).
Installing pristine 10.04 netbook remix did not work, but upgrading it to 
2.6.32-22 made wireless alive to some degree. Scanning worked, I could see my 
neighbors routers, but I could not connect to mine.
After some experiments I figured out that I can connect when I set my router to 
WPA/WPA2 Personal & TKIP.
Setting router to AES or AES+TKIP makes connect attempt failing after long 
(minutes) trying. 

Bear in mind, that I have a desktop ubuntu install of the same version,
and it works with router in AES mode just fine (Zonet ZEW2500P usb
adapter). So, OS is the same, router is the same, and only HW and
drivers are different.

Also something unexplainable happen to open (unencrypted) router
connections. They failed too ( I tried 2 of them). But after I managed
to connect to my own router, I checked open connections and was able to
connect to open ones. I rebooted severl times in between, so it hardly
can be wireless card stuck in a strange state.

So if your symptoms are: scanning works but you can't connect, please
report your *router* settings too. And give it a try WPA/TKIP.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Xebec]

Karmic + 0014.0115.2010 driver used to work wonderfully. Now I have the same 
issues, just as with first driver versions in 2009:
Router's Tomato firmware reporting signal quality:
Windows 7: 10-12
Lucid: 3-5

Basically the signal is garbage once again. Could you fix the driver to
work just as Windows driver works?

Lucid with the latest standard kernel + 0015.0127.2010 driver.
Unfortunately back to square 1. :( Transmission signal strength is
horrible again. My WIndows 7 has rock-solid connectivity, while Lucid
takes minutes to connect and retains the signal for 1-2 minutes before
dropping of into endless retries. I'd be glad if you fixed the issue.

[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510

[Peter Funk]

I did a fresh install of a Lucid .iso on a HP Compaq 610 today.
This computer contains a Realtek 8171se WiFi chip. WiFi didn't work first.
The installation .iso still contained kernel image 2.6.32-21 
Downloading the file 
http://de.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-image-2.6.32-22-generic_2.6.32-22.33_i386.deb
manually on another computer with Internet Access and copying this single file 
using an USB-flash memory stick made it possible to upgrade the kernel on the 
new machine and after the reboot WiFi worked fine.  I would like to thank 
everybody for their nice work!

Just popping in to say I came here from a different bug that was marked

I had been havign issues connection to aps... I could see APs, but when
I entered the password it would just time out after ~30 seconds.

I followed the suggestion in there...

using this .deb solved all my wireless issues: https://launchpad.net

Porbably slightly off topic, so feel free to tell me to piss off:
Should I still upgrade my kernel? (I had to disable KMS to get 10.04 to boot on 
this Lenovo X201, because it uses the i5's integrated graphics card, which is 
very new and has some issues:

Unfortunately Launchpad doesn't like my report, timeout :( Here is the
description of the bug and dmesg log attached

Several issues installing kernel from proposed emerged. My wifi is using
rt73usb. It's a D-Link DWA-111 (I'll provide the exact chipset later)

 * on system startup, the card is unable to connect to router, filling
the textual console with following error message "phy0 ->
rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed for offset
0x30c4 with error -108."

 * unplugging the USB card, the related kernel module is not unloaded

 * re-plugging the USB card, it seems unable to "turn on": the activity
led is off and the plugging is not reported in logs

 * removing and uploading the kernel module, the following messages are
showed by dmesg

[ 4096.249323] phy2 -> rt2x00usb_vendor_request: Error - Vendor Request 0x09 
failed for offset 0x with error -108.

Maybe I've found a potential regression to this change. Upgrading in
10.04 from kernel in -main to kernel in -proposed, my realtech based
WiFi card (rt73usb driver) stopped working. I've added a small and quick
description in latest comments for bug #362875 (initially I wasn't
thinking about kernel from -proposed). I'll open a full bug report, just
the time to restart, collect data and send to launchpad.

Hi Rikki,
 I just wanted to follow up with you and explain what Steve's comment above 
means. The patch to fix your issue has been accepted as an SRU to be included 
in the next update. What we need from you is to go to the EnableProposed in 
Steve's comment and enable it, update it and verify that you are still in a 
good state. Once you do that, you would report back here any issues or if the 
update was successful. Let me know if you need any help.

Thanks!

SRU Justification

Impact: rtl8192se vendor driver does not work consistently. The vendor
has made many improvements since the initial (not very robust) version.

Patch description: Update vendor driver to 0015.0127.2010. This version
has much better integration with cfg80211.

Patch: https://lists.ubuntu.com/archives/kernel-
team/2010-April/010295.html

Test results: It appears to have fixed at least one user's problems. See
previous comment from Rikki.

I walked through it all again and rebooted & it's working (I'm really
not sure what part I didn't do the first time, but whatever I skipped
was important). So, I don't have anything to add to JFo's instructions
above except to make sure you follow them closely and don't skip a step.

Hi Rikki!
  Here is some further detail on what you need to do.

Go to https://edge.launchpad.net/~timg-tpi/+archive/ppa/+packages to get
a good view of all the packages in Tim's PPA.

Click on the name for linux - 2.6.32-22.33~lp567016 which will open
details about this particular package.

At the bottom of that expansion there should be 2 choices, amd64 and
i386. Select the one that is appropriate for your hardware.

This will bring you to the specific information for your particular build of 
the package. At the bottom of the page are all the packages that were built by 
Tim for this test case. I suspect that the 2 you will need are:
linux-headers-2.6.32-22-generic_2.6.32-22.33~lp567016_.deb  and
linux-image-2.6.32-22-generic_2.6.32-22.33~lp567016_.deb

you will need to save these to your machine (this will probably take a
while to download depending on your connection)

Instructions for installing the packages is available at
https://wiki.ubuntu.com/KernelTeam/MainlineBuilds in the section titled
"Installing Mainline builds.

I'm available on IRC (as JFo) should you have any issues with the above
information. :-)

Thanks!

Rikki - Unfortunately your laptop contains an rtl8192se wifi adapter
that is not supported by upstream. The kernel team chose to integrate
the Realtek vendor driver which is still in a state of development. I've
updated this driver to the latest version that I could find
(0015.0127.2010 has substantial changes) in the hope that it may solve
your problem. If not, then I may have to have actual hardware in order
to figure it out.

Please try installing linux-2.6.32-22.33~lp567016 from my PPA at
http://launchpad.net/~timg-tpi/+archive/ppa when it has completed
building.
