[ath9k] AR928X fails to reconnect to WEP/WPA network after suspend/resume

[andrewpmk]

On a Toshiba Portege M800 with an Atheros AR928X using the ath9k driver, running Ubuntu 8.10, the wireless card does not reconnect to a WPA or WEP encrypted network after suspend/resume. Unencrypted networks seem to work fine. This seems similar to the behavior in bug #278190 but I am running kernel version 2.6.27-11 and this does NOT fix the problem.

Relevant line in lspci -nn:

08:00.0 Network controller [0280]: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01)

Workaround (from http://ubuntuforums.org/showthread.php?t=1017306):

Either rmmod ath9k, then modprobe ath9k after suspend/resume, or add the following text to /etc/pm/config.d/00sleep_modules:

SUSPEND_MODULES="ath9k"

Hi andrewpmk,

When running the 2.6.27-11 kernel, per the kernel team's bug policy, can you please attach the following information. Please be sure to attach each file as a separate attachment.

* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

It would also be good to capture and attach your dmesg output before and after you suspend/resume.

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help and feedback.

[andrewpmk (andrewpmk)]

Output of dmesg after the suspend/resume and the failure to connect. What happens is that the network manager tries to connect for a while, then pops up a window asking for the WPA password. If I enter the correct password, this repeats itself. The relevant part of the log is at the end.

Hi andrewpmk,

Wow, sorry for the extremely delayed response here. Can you also try installing the linux-backports-modules-intrepid package and see if it helps at all? It contains and updated compat-wireless stack. If that is still problematic, you may even want to test the latest bleeding edge upstream compat-wireless stack - https://wiki.ubuntu.com/KernelTeam/LinuxWireless . Let us know how it goes. If the issue remains in the upstream stack, we'll want to notify the upstream developers. Thanks.

Need user info.

[Leann Ogasawara (leannogasawara)]

Due to no response I'm going to close this for now. Please feel free to reopen by setting the status back to New if this issue remains in the latest Karmic 9.10 Alpha release - http://cdimage.ubuntu.com/releases/karmic/ . Thanks.

I had the same issue on an Asus PC 1000HE with the same Atheros chip on 9.04, but the workaround gets the success rate of getting wireless up after suspend up to roughly 90% (estimated, not measured).

On 9.10 alpha 4, this is still an issue, though wireless comes up after suspend, but only works for a couple of seconds (say 10), before wireless network hangs for say 30 seconds, and then you get new 10 seconds of working wireless (and so on). This is progress from no networking, but still not usable.

The same workaround using /etc/pm/config.d/somefilename with SUSPEND_MODULES=ath9k solves this problem.

$ lspci -nn | grep AR928

[Håvard Berland (berland)]

Attached output in dmesg.log while network comes on and off in intervals

[Håvard Berland (berland)]

I see that the behaviour after resume is identical to what reported in bugs #414560 and #407981

it can see networks but fails to connect, even with correct passwords and even if a password is not required

as a sidenote, it does on occasion connect, but then the little light that is on the card flashes rapidly and then fails

if there is a log i can attach let me know, im runing ubuntu 9.04 and im not sure of my kernel right now, any information i will provide, if you need to email me to remind me to come back, please do so ;)

if these are not what you asked that other guy for, let me know so I can delete it and not fill this bug with spammm

Ubuntu 9.10 seems to have this issue resolved (though the led connected to the wireless card still blinks randomly for no reason on occasion)

[fristedt (peter-fristedt)]

Sorry, problem persists in Ubuntu 9.1 (AR928X wifi in a Fujitsu ESPRIMO Q5030).

I can confirm this behaviour on a Dell Studio XPS 13 with the same Atheros card:

06:00.0 Network controller [0280]: Atheros Communications Inc. AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01)

THis computer is running Ubuntu 9.10 with all updates:

Hi all,

Since problem persists, please, can you try this two options.

1. Can you please try installing the following package. It contains an updated compat wireless stack which may help.

linux-backports-modules-wireless-karmic-generic

If the issue still remains even after this, I'd encourage you to also try installing the latest compat-wireless stack from upstream -
http://wireless.kernel.org/en/users/Download . This will allow us to escalate this issue to the upstream developers. Please let us know your results

2. Please can you try also with last kernel version, which is located on http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32/?

Thanks to all in advance.
