yesterday I let the update manager install a whole bunch of updates for my 10.04 install on my MSI Notebook ER710. My wireless was just working peachy until then (with the madwifi drivers), but after the update, no more... I checked the madwifi, tried a new make, but nothing worked.

So, after reading somewhere that 10.10 had less issues with wireless I decided to upgrade to 10.10 in the hope that that would solve my problem.

Well, partly it did, as in, according to my system I've got a wireless again and this morning even, it was able to see wireless networks! Unfortunately I couldn't connect to mine, although the key was correct. At some point I lost the ability to see wireless networks again. I tried wicd too, but no luck their either. It recognizes my card but can't see any networks.

Any help would be appreciated, here is all the info: (PS I posted a similar question here once, but then I'd just forgotten the on/off switch of the wireless, no such luck this time, it's on)

You need to blacklist the ath5k and activate the madwifi drivers.

I already tried the madwifi route again, but no luck, but this link has some extra information. I'll give it another shot and let you know. Cheers! – Peter Dec 17 '10 at 11:21
And there we are! I followed those much more detailed instructions then the ones I had and it work! Wohoo! Thanks a million Bubu! – Peter Dec 17 '10 at 12:17
