The issue is I have to constantly switch between the two wireless networks on campus - very annoying. The connection will still be there, but it will stop connecting to the servers. This is better than before, when I couldn't even connect to the internet. I also cannot connect via ethernet now and the option 'Auto Ethernet' is not available in the network menu.

I am running 12.10 on a Toshiba satellite C855. I already installed the correct driver for my realtek card, but this particular issue started when I updated my kernel to get rid of the apport error. The kernel is 3.8.1-030801-generic (which is not an ubuntu kernel... even though the link I got it from was an ubuntu website). Here are the instructions I followed:

Everything else is working fine. As far as I can tell it's only the wirelss/wired issue that is effecting my usage. Would this issue be solved by changing kernel to an ubuntu kernel? And if so, how would I do that?
