[SOLVED] Computer crashes after connecting to wifi

Postby kdamica on Wed Mar 06, 2013 1:17 am

Hi all,

I've been using mint on my laptop for more than a year now, but a few months ago my wireless completely stopped working. It would get through the authentication and and hang while obtaining IP address. I ended up taking out NM and installing wicd, which I found out crashes my laptop after it hogs up all the memory. This was not an unheard-of problem, and the solution was to install wicd-curses, which I did. Curses will open, but for a while wouldn't connect, hanging while obtaining IP address like NM. Then I gave up for a while and just used a wired connection. But recently, I tried connecting again and it did, but the computer crashed to a bunch of text after maybe 30 seconds. It does this every time now. I don't understand what any of the crash text means, but the word 'panic' is used. A little more info: I have always been able to connect to unsecured wifi connections, but the computer would always crash after a few minutes similarly to what it does now.

I'm using a Toshiba Satellite C655-S5068, which has an Atheros card in it. I've tried uninstalling and reinstalling ath9k, and various other things I've found in forums, but nothing's worked.

Any help or suggestions would be awesome.

Thanks.

I finally checked in the ath9k bugs list and saw that there were some others having this problem. The bug was fixed in a recent push. Upgrading to Nadia got me to a working version. All is well.
