Wireless problem on UNR after update

[sharkyZA]

Hi Celtichboy

No, using ath_pci that runs standard on UNR 9.04. After fiddling with madwifi last time, it also only working for a day or two, I reinstalled and only uncommented the blacklist thingie to get wireless working.
Now after many days of wireless happiness things have gone south again, without warning and preperation...

Thoought this might shed some light: (to someone who has a little more insight than I)

Hi.

I'm not an expert in neither Linux nor Ubuntu (yet ) but I have read somewhere about Wi-Fi issues on the AA1 and the trick was to flash the Bios to a newer version. I myself run UNR on a Bios version 3309 and my Wi-Fi works great out of the box. When I flashed my Bios I followed the guide on macles blogspot.

I have flashed the BIOS recently with 3309 to get the fan mod to work with lower settings, unfortunately my wireless still goes out the window every day or two. But I'm glad to note that your solution will work with a fresh install. I'm not very eager to re-install though. It took a lot of tweaking to get everything setup like I want and a lot of bandwidth to download all the extra stuff that is not in the distro.

What is happening here since I last posted: The wireless packs up. Then I run

sudo modprobe -r ath5k acer_wmi 
sudo modprobe ath5k

Read that someone else does this, and voila! Wireless running again. Undetermined period goes by, wireless packs up again... we enter the modprobe commands and happiness returns.

I don't know if the wireless packing up is based on elapsed time, or data throughput or other rather special autoset parameters, but it is slightly annoying. But at least, being able to 'reset' it is a bit less annoying than not being able to use it at all.
