Bug Description

Similar to bug : https://bugs.launchpad.net/ubuntu/+source/linux/+bug/984552

Saw the following in the logs :

Aug 13 17:22:52 Galois kernel: [32696.796323] iwlwifi 0000:02:00.0: restoring config space at offset 0x1 (was 0x100006, writing 0x100406)

When I first wake the computer, or boot the computer, wireless attempts to connect about 15-20 times before finally connecting.

Once connected, speed and latency vary randomly, but mostly on the slow/high side respectively.

When I test my connection speed with a site like speedtest.net, I'll usually get full speed for about 1/2 a sec , then it goes to zero for awhile, then comes back on at full speed a second later or so.

With windows, connected to the same router, none of these problems occur.

AP : Netgear WNDR3800, firmware version 1.0.0.38 (latest).

Connection type : 2.4Ghz 802.11n (I tryed changing to 802.11g and this didn't fix it).

No other devices have the issue with the AP, including Android, Mac, and this machine on Windows.

The distance to the AP is 3 feet, with no obstructions. Changing the distance does not seem to affect the problem.

I don't know if the issue occurs with other APs. I'll be taking this laptop to school soon, I'll update when I attempt to connect to another AP.

I don't know if this is a regression, this laptop is a brand new warranty replacement, so I haven't ever had this model of wireless card before.

The compat-wireless did provide a provide a WORKAROUND or solution following https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-wireless_in_Ubuntu!

So the compat-wireless workaround seemed to fix the issue, do you need anything else?

Israel Vaughn, glad to hear compat-wireless works. If this works for you as a solution, could you please mark this as Status Invalid?

Revision history for this message

Von (daaxix) wrote on 2012-10-09:

Actually, it is still here. I noticed something different today, perhaps the compat-wireless workaround was conflated.

Ping times are fine, when AC (mains) power is plugged in. When I'm on battery is when the ping times go up to 500+ms.

I'm usually plugged in, so I perhaps thought that the compat-wireless fixed it.

sudo iwconfig wlan0 power off

actually fixed it. Is this a regression?

Israel Vaughn, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.7-rc8

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

This is definetly a regression, using debian 7 with kernel 3.2 the problem isn't present.
