I'm running Mint 12 64 bit and my WiFi chipset is an Intel Centrino Advanced-N 6205.
My WiFi connection at home works fine. Here I am connecting to a wireless G router with WPA2 PSK security.
On campus, however, is another story. There are two networks available there - one an old G network with a WEP key, and another new one which has N connectivity and uses 802.1x PEAP security with a user name and password. Both of these networks are horribly unreliable for me - the connection only works for a few minutes before either websites refuse to load while the system claims it is still connected or it disconnects outright. These connections were stable on Windows.
At first I thought the connections might be dropping because I have the TLP power management package installed and configured to save power on the WiFi chip, but I tried disabling this and it made no difference. Also, this wouldn't explain why the connection is stable at home. I imagine this isn't a driver issue either, for the same reason.
I googled around a bit and found some suggestions to try WiCD instead of the gnome network manager but I somehow managed to make gnome-shell dissapear when trying to do this and only Gnome classic and MATE were available at the login screen (fixed now) - is this worth trying and what would be the right way to do it?
