View Full Version : UNR Jaunty, AspireOne ath5k is disconnected.

May 1st, 2009, 02:42 PM

I have installed Jaunty UNR on my AspireOne 110-Aw and everything was fine. But today I couldn't make a wireless connection (or find one), I don't know why.

So after some searching on the internet I installed linux-backports-modules-jaunty, blacklisted ath_pci, ath_hal and acer_wmi in /etc/modprobes.d/blacklist.conf, added ath5k to /etc/modules, checked if ath5k was blacklisted anywhere in /etc/modules.d/, ran 'modprobe -r ath5k acer_wmi ath_pci ath_hal' and then 'modprobe ath5k' (and a reboot).

This in order to get the (much advised) ath5k wifi drivers/module.

They seem to be loaded, according to nm-tool, and the wifi LED does burn at least on start-up but ath5k is disconnected. I'm not sure what to do next, couldn't find anything on teh internetz sofar.

Included some terminal outputs which I hope are useful :)

nm-tool output:

For the interested... turning power off for a while did seem to work in my case.

yeah I have the same symptoms, tried dmesg and got the same result as you, I am using the Acer Aspire One ZG5. The ath5k drivers are really choppy, sometimes it works, sometimes it dosn't this is quite annoying since the main purpose of a netbook is to go on the net!

PS the buy report is here if anyone needs it https://bugs.launchpad.net/ubuntu/+source/linux/+bug/269253

I had the exact same probelm with Acer AspireOne A110. Removed UNR shortly after discovering the bug.

EDIT: Oh, just found a workaround for it:

I have the same issue on a Toshiba Satelite A215. But it got worse after I switch from the 'stock' 5400rp disk to a larger 7200rpm.m
Now the area of the disk seems to be getting warmer, and the WiFi is worse!
