[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se
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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/567016 Title: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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: http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1PNid=21PFid=48Level=5Conn=4DownTypeID=3GetDown=false. 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 https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper 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. -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

@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. -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se
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 -rfing 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. -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se
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. -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se
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... -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se
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. -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 567016] Re: Wireless won't work on Lenovo Thinkpad T510 - rtl8192se
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. ** Changed in: linux (Ubuntu Lucid) Status: Fix Released = Confirmed -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 ** Changed in: linux (Ubuntu) Status: Fix Released = Confirmed -- Wireless won't work on Lenovo Thinkpad T510 - rtl8192se https://bugs.launchpad.net/bugs/567016 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
