I have Ubuntu 12.10 on my laptop. For some reason - I don't exactly know which one - my wifi module doesn't work. So, I bought an external wifi module ASUS USB-N13.
I've installed all required drivers, but I still have to run this command on every system startup to make this adapter work:
sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
If I don't run this command in the network utility at the top of the desktop I see that wifi is disabled by hardware switch. So, I run this command to make adapter work.
And here's the question: after some time(may be 5-10 mins) connection is lost. I still can see all wifi networks enabled, but when I try to connect back to my home network password window appeared. When I enter my password windows disappears and in a minute it appears again. The password I'm enter is surely right. So, I have to unplug usb adapter and plug it again and after it wifi start works in normal mode for 5 or 10 mins and after it everything is back. Any ideas how I could solve my problem?
Thanks in advance.
