[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
Hi! Have issues with my 5300 card, and i made some testing. wireless n is unstable if you add ap_scan=1 or scan_ssid=1 in wpa_supplicant.conf if i set them to 0 and add my network into wpa_supplicant.conf it connects at 300mbit/s if i do som bwtesting i get good n performance! as soon as i enable one of these settings, the tx bitrates starts jumping up and down... if i enable debugging i wpa_supplicant i can see that it goes down to 1mbit everytime a CTRL-EVENT-SCAN-RESULTS is made. iw wlan0 link tx bitrate: 1 Mbit/s - when scanning (jumping up and down) tx bitrate: 300 Mbit/s - when scanning is disabled. dont't know if it help you to figure out the problem i still get some Tx excessive retries: and Invalid misc: but the performance is better! /Mikael -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/630748 Title: iwlagn degrades quickly during normal wifi session To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/630748/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
Gotta love the enterprise polish Ubuntu brings to Linux! At http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2214 it seems that the bug has been fixed lately (for some people at least) by the guys at Intel. As with the severe power usage regression, Ubuntu seems to be unable or unwilling to do anything except package other people's software when the problem is anything except a marketing issue... Since the bug has been marked as fixed (by the equivalent of disabling the high-end features of the device), I doubt we'll see any real resolution.

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
Hello Jan, probably both (unwilling and unable), but I don't think it is Ubuntu's purpose to fix these problems. It all goes back to how much does Canonical contributes to the Kernel, Ubuntu is supposed to give users a good user experience in terms of ease and quality or packaging, I love Debian, but Ubuntu is always more cutting edge. I'm not blaming the Intel guys, but this problem should be fixed by the iwlagn dev guys. Once it gets fixed, it will get incorporated into Ubuntu (or rather into the Linux kernel distributed by Ubuntu). By the way, what do you mean by regression? You mean the 2.6.37-2.6.38 (aka pci-aspm power regression) or the iwlagn power savings feature?

I have tried all the options in the hope to get the speed stable.

Are you sure? I can connect, and it's quite stable, the problem happens
after some hours.
What does dmesg output (after some minutes of connection)?
I've tried iwl4965 with 2.6.39, but it's very unstable ):, I'm sticking with
2.6.38 for now (even though it's not perfect either)

Hi Pedro. I have tried disabling 802.11n both in Natty and on my router, but the problem persists. In my /lib/firmware I have iwlwifi-6000-4.ucode (I'm assuming this is the latest, couldn't find anything more recent). I'm not sure what compat-wireless is or how to use it, but you look it up immediately after this post. I have also ordered an Intel Ultimate N WiFi Link 5300 Network adapter. I'm just not sure if this adapter comes with Bluetooth. I was looking for an older 802.11g network/bluetooth combo but they're surprisingly difficult to find here (UK).

Re: [Bug 630748] Re: iwlagn degrades quickly during normal wifi session
compat-wireless is a package of drivers from the latest kernels, but you can
compile them for older kernels.
You can get them here: http://wireless.kernel.org/en/users/Download
http://wireless.kernel.org/en/users/DownloadI thought of disabling n on
your module by creating a file in /etc/modprobe.d/ (something
like /etc/modprobe.d/inteldisablen.conf
and including: options iwlagn 11n_disable50=1 11n_disable=1
after that try:
sudo rmmod iwlagn
sudo modprobe iwlagn
Unfortunately, I believe 5300 will also have the same problems ):

Re: [Bug 630748] Re: iwlagn degrades quickly during normal wifi session
So it seems like 6200 has bigger problems than 4965.
Have you tried the latest microcode? (although I assume natty is already
using them).
How about compat-wireless?
If you disable 802.11n, does it solve your problem? (As in a workaround, not
a real fix)

I recently upgraded my lucid laptop (thinkpad X200s) to maverick. I
found after the reboot that my wireless degrades after about 8 hours
of ordinary use. I had 45% packet loss direct to my WAP, and this was
easily cleared up by doing modprobe -r iwlagn; modprobe iwlagn as

Please disregard my last comment. I discovered that the problem was my HDD - a Seagate Momentus XT Hybrid (which has 4GB of SSD and uses a cashing algorithm). I tried upgrading the firmware on the Momentus XT to D25, but this only made my networking problems in 11.04 worse.

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
I have a Sony Vaio VPCF11S1E/B. Executing lspci | grep -i network produces: 02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35) I am running the final release of 11.04 (all updates have been applied). WiFi network functionality is unreliable, this is especially apparent when streaming (watching YouTube) or trying to download large files (anything around the 1GB mark). Everything starts off fine, but within minutes the download (or stream) will grind to a halt. I have tried stream and downloading the same files when I boot into Windows 7, and everything works without any problems. Also, running speedtest (http://www.speedtest.net/) the results are consistently 33% slower in 11.04 compared to Windows 7 or another laptop running 10.10 (friend's laptop). In 11.04 it feels like the downstream is capped at 20Mb/s. This is a difficult problem to pin-point (for me) as initially I thought it may be the server(s) I'm downloading from or my ISP. However, after running a battery of downloads (torrents, podcasts, linux distros) and repeatedly watching YouTube clips on both Ubuntu 11.04 and Windows 7, I can confidently say that the problem lies within Ubuntu 11.04 (somewhere). It's so annoying that I cannot continue using Ubuntu 11.04 as I can't even watch a 10 minute YouTube clip without the stream freezing within 2 or so minutes. I hope that a true fix will appear soon as I dread the thought of returning to Windows 7. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/630748 Title: iwlagn degrades quickly during normal wifi session -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
I've installed 11.04 on a separate partition and with my 4965 card I seem to be running just fine in N mode (by default, out-of-the-box). I installed a few hundred megs of updates with no trouble other than a couple few second pauses (but that may well be more due to the repos than my connection).

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
Alexander, Andrew - I removed the 802.11n exclusion parameter for Natty on the advice of the primary Intel wireless developer. She said she believes the issues with 802.11n on the 4965 part have been fixed. Note that there is only _one_ driver that services all Intel wireless parts (except for 3945), so the 802.11n parameter affected 100/103/4K/5K and 6K parts, all of which have different firmware and varying levels of 802.11n support. If some of these parts prove problematic wrt N support, then I'll look at enabling N exclusion by default within the kernel for only the parts that exhibit problems. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/630748 Title: iwlagn degrades quickly during normal wifi session -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Support for 4965 is still contained in the iwlagn driver even though considered a legacy device.

I don't understand this comment either and agree with Alexander Hall; It sounds like 4965 should get working 802.11n in patch.

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
The .38 compat-wireless package can be found in maverick-proposed repository. I just retested this on up-to-date maverick, with the compat- wireless-2.6.38 package from maverick-proposed and latest firmware from Intel (8.83.5.1, dated 2011-02-25). Hardware is Acer Aspire One with Intel 5300 mini-pcie card and Netgear wndr3700 running official firmware and using 5GHz channels in either .11a or .11n modes. This works fine with 11n_disabled, using .11a mode, with both drivers and firmware versions. Of course the speed is limited, but I can for example stream a 256k internet radio stream over http and use ssh terminal connection without any noticeable problems at the same time. After removing the 11n_disable, the ssh terminal connections seems to have a noticeable lag and data comes in in bursts. This feels worse than with .11n disabled, although not as bad as with previous driver and firmware and the performance stays on a constant level without degrading over time. Then after 5 to 10 minutes the data stops flowing. This time the driver doesn't oops, but notices the problem and forcibly reloads the card firmware. Data starts flowing again without manual intervention, except that the firmware reloading takes long enough to break audio streaming and some file transfers. So better than previously, especially as the driver doesn't oops anymore, but I wouldn't call this usable yet. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/630748 Title: iwlagn degrades quickly during normal wifi session -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I don't know why, but even though I get the received BA when not expected
I don't have too many connections lost (I'm not sure about slowdowns
though).
It annoys me a little, but the extra range is worth it, I live in a building
made out of reinforced concrete (concrete with a metal grid inside) so the
connection quality drops substantially after a wall.

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
Just wanted to add that intel will not be fixing this issue for legacy devices, including the 4965agn: In reference to the splitting of the iwlagn driver with a legacy branch, will the 4965agn get a similar fix. These network cards have similar issues, including the Received BA when not expected errors. It will be very difficult to add the same firmware fix for legacy devices including 4965. I am really sorry about it.

Re: [Bug 630748] Re: iwlagn degrades quickly during normal wifi session
I'm not sure, but I think that fglrx is to blame for that.
I had a HD3200 and every time the kernel was updated I had trouble. Try the
radeon driver instead (I guess you need to unblacklist it firts)
I'm running it pretty reliably on my X300, Intel 4965, but haven't tested
all that thoroughly.

I just tested it using 2.6.38-rc5-git6 built myself on Ubuntu 10.10 (not the latest but damn close) and things didn't seem to tank like they used to but they are still only transferring at about 5MB/sec after a bit.. Now after a fresh reboot I'm getting about 9-10MB/sec. I finally booted into windows just to test this out an it was never seeing under ~13MB/sec. But I didn't test long as there were millions of updates wanting to install since the last time I used it. Anyway I'll run like this for a few days and report back...

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
I have an Intel PRO/Wireless 4965AGN Mini-PCI Express in my laptop, and when I comment off the line that disables N wifi, and connect to 5GHz N, it works just fine, at 270 Mb/s. I stressed it hard for 15 minutes or longer, just to be sure. If it stops working after a number of hours, I'll post another comment. As mentioned in comment #27, I think that Linux Kernel commit 1c3a1973b2d7c46c886d243367dcc5988a4ef704 may have been what fixed the problem. I did not have an 802.11n capable router until fairly recently, so I don't know if it used to work or if it had the bug before the disable-n thing was put in there. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/630748 Title: iwlagn degrades quickly during normal wifi session -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
I've tested the experimental firmware (iwlwifi-5000-exp-8.83.5.1) with a 5300 card and kernel 2.6.36.2. Initially it seems to have solved the problem. iwconfig reported bit rate maxes out at 300 Mb/s (though it drops to 6 Mb/s during inactivity). File transfer rates are significantly greater than they were with N disabled. There are quite a few of the following messages in the syslog, but that may be expected given the kernel debugging options necessary in order to run the experimental firmware. iwlagn :03:00.0: Aggregation not enabled for tid 0 because load = 1 iwlagn :03:00.0: iwlagn_tx_agg_start on ra = xx:xx:xx:xx:xx:xx tid = 0 iwlagn :03:00.0: Aggregation not enabled for tid 0 because load = 2 iwlagn :03:00.0: iwlagn_tx_agg_start on ra = xx:xx:xx:xx:xx:xx tid = 0 iwlagn :03:00.0: iwlagn_tx_agg_start on ra = xx:xx:xx:xx:xx:xx tid = 0 However, after about 10 minutes of inactivity, the connection becomes inoperable. Reloading the module fixes the problem temporarily, but it hasn't held a connection for more than 15 minutes at a time. This is significantly longer than without the experimental firmware, but it doesn't seem to have completely fixed the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/630748 Title: iwlagn degrades quickly during normal wifi session -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 630748] Re: iwlagn degrades quickly during normal wifi session
I'm thoroughly confused. Yesterday I enabled N on my WAP and the previously rock solid wireless connection for my Intel 5300 equipped T500 became very unstable. Several times the connection dropped to the point where network-manager presented me with the password page. At other times it would drop and recover in a few seconds without intervention. I found this bug report while trying to resolve the problem. My T500 is still running 10.04. I added the file /etc/modprobe.d/intel-5300-iwlagn-disable11n.conf with contents [code]options iwlagn 11n_disable=1[/code] and executed: [code]sudo rmmod -f iwlagn sudo modprobe iwlagn[/code] and the card is still using N. Next I tried: [code]sudo rmmod -f iwlagn sudo modprobe iwlagn 11n_disable=1[/code] Still running N and still unstable, though it did settle down and remained connected (or at least did not give up and ask for the password) overnight. I have found information scattered throughout forum posts but have not seen any that seem to have better info than what's in this bug report and that seems less than complete. Questions I have: Is 10.04 subject to the Intel firmware problem (or should I be looking elsewhere for a solution to my problem.) Is the syntax I'm using to disable N correct? Is that option not supported by the module in 10.04?
