I bought an Acer M3-481. I am running 12.04 64 Bit with an Atheros Wifi Module. My WLAN router to which I'm trying to connect to is a Thomson TWG850 device. It seems that this device crashes every time I connect to it using this PC only.
At the beginning I thought my own wireless module on the notebook would crash. After looking at my mobile phone (android) I realised that the router kicks out all devices conntected to it. So after I shut down Ubuntu I tried with my W7 PC and everything works fine.
Furthermore, each time that happens, Ubuntu asks me for my WLAN Key (WPA). Ubuntu send out a system report for an internal error stating that the "WPA Supplicant hast crashed". I am not sure if this has anything to do with the WPA I am talking about.
Other Forums suggest deactivating N-Modus on Ubuntu or on the Router. This unfortunately doesnt help me. I have been looking in many forums, but theres no real help. A lot of people seem to face the same problem.
I am sorry, very new to ubuntu so if you need anymore info about the system, please tell me how to pull those. Sorry.
