I have a dual-boot of Windows 7 and Ubuntu 11.10 on my MSI X350.

During the installation process and some time after the wireless worked just fine and I used the internet connection to install updates and everything.

(I think) because of the distance to the router I sometimes had to reconnect manually (click on the wireless button in the syslink and then click on my wifi network), but that was ok.

The problem is that one time I could not reconnect so I shut the wifi off and on again to try another reconnect, but since then I wasn't able to reconnect to the wifi and now I cannot even switch on the wifi anymore (it seems permanently disabled or something). Under Win7 however, everything works fine (wifi connection and internet, as before).

tl;dr : My wifi used to work under Win7 and Ub11.10 and then stopped working under Ub11.10.

Info/Hardware(hopefully it's readable, because I had to save the logs and open them again under Win7 and the formation was lost):

Ok, I resolved the problem myself.
My wifi is switched off after boot up and I just didn't switch it on. No wonder I didn't get a connection.
Thanks for your time.
