No wireless for Atheros AR9285

[Morten Juhl Hansen]

Hi there
I have a problem with my HP dv6 2050eo after upgrading from 9.10 to 10.04 and then to 10.10. The network manager doesn't show the available wireless networks in 10.04 and 10.10.
If I boot up in windows or on a live cd with 9.10 (and when I had the 9.10 working) the networks are visible and available.

I have this info from the 10.10 with the ethernet working.

[Robert Roth (evfool)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please answer these questions:

* Is your laptops wireless switch switched on?
* Does your laptop have a keyboard shortcut for enabling/disabling wireless?
* If the answer for the above question is yes, does turning on your hardware wireless switch and toggling the wireless using the keyboard shortcut change anything?

This might help us to find and resolve the problem.

[Paddy Steed (paddy-steed)]

Can you please run `iwlist wlan0 scan`

[Morten Juhl Hansen (morten-juhl-hansen)]

Regarding the wireless switch on the laptop - it is active (blue light) and if I right-click the network manager icon, it says wireless network 'not connected' (something like that - i'm running the danish version) - but if I touch the laptop wireless switch, it turns red and the right-click on network manager icon, says 'deactivated' for the wireless network.
I have no knowledge of a keyboard shortcut switch.

Regarding the iwlist:
morten@morten-laptop:~$ iwlist wlan0 scan
wlan0 No scan results

Thank you for your efforts

Regards
Morten

[Fabio Marconi (fabiomarconi)]

Hello morten
i don't want the cdlive files, i want the not working filesystem files.
run the live cd session, click on places, computer, hard disk icon and browse till requested files, then copy it to the desktop, then attach them here.
Thanks

Hello Fabio

With the rc2 kernel the system won't start up in the GUI - it states something with fail regarding some MMIO registers. I'll attach the Xorg.o.log if it can help.

[Fabio Marconi (fabiomarconi)]

Hello Morten
Can you switch to a console (ctrl+alt+F1) login and type
sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old
elsewhere run a live cd and rename the file /etc/X11/xorg.conf to xorg.conf.old
save and reboot

Hi again Fabio

Still it won't start up the GUI. But instead in the commandline like logon. After logon i have tried to submit the 'startx' command, but this doesn't do anything. Then i tried with a new reboot - didn't help. I have attached the Xorg.0.log.

Hello Fabio

I have just tried with the Ubuntu 11.04 alpha 1 version - booting from a usb stick and then 'try Ubuntu'. The system still won't present the available wireless networks :-(

that ship the 2.6.37.9 kernel

[madbiologist (me-again)]

The 2.6.38-rc6 kernel contains a possible fix for this problem. A PPA of this kernel should soon be available at http://kernel.ubuntu.com/~kernel-ppa/mainline/
This kernel will also soon make it's way into the upcoming Ubuntu 11.04 "Natty Narwhal", hopefully before alpha 3 on March 3rd.

[Morten Juhl Hansen (morten-juhl-hansen)]

Sorry to say, but the 2.6.38-rc6 didn't do the trick for me. Just using it with the 10.10 ubuntu resolved in a commandline logon screen. Then I tried the natty from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38-rc6-natty/ in a live session using a usb stick, but after boot up there was still no available wireless networks presented. If you're interested in some logs, please let me know.

this is also a problem in natty... no driwer for ath9k wifi

[raggar (mbaart)]

On a fresh natty 64 bit installation.
Wireless connects, but drops constantly in the first 15 minutes. After that it's stable. But when disconnected, same problem.

on the other hand, if it works fine if I skip the scanning and bring it up by hand... :

Once it is connected, iwlist scan works, finding my network, and a few others in the area.
This is fresh install of natty. This is a regression as the same card worked fine under 10.10.

should this be same bug, or separate?

Hi

Just a short update to this.
I have upgraded to 11.04, but that had no effect on the wireless - it's still not visible in networkmanager.

There is the following info from the 11.04 system:
morten@morten-ubuntu:~$ sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | grep ound; dmesg | grep irmware ; dmesg | grep ipw; dmesg | grep eth; dmesg | grep ath; dmesg | grep b43; dmesg | grep witch; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

[Seth Forshee (sforshee)]

The upstream bug is reporting a problem when using AR9285 as an access point. In the reports here the wireless is in either ad-hoc or managed mode, so the upstream bug really isn't the same as the issue reported here. Removing the upstream bug tracker.

Note that if you are trying to connect to an access point you should be using managed mode rather than ad-hoc.

Please test the 2.6.38.8 mainline build to see if the problem persists there. If it doesn't we can look into a bisection to try and track down the commit that introduced the problem. The 2.6.38.8 mainline build is available at:

  http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.38.8-natty/

Thanks!
