It would be helpful to see the output of the commands:
Code:
dmesg | tail -25
dmesg | grep -e wlan -e ndis
immediately after you get disconnected. With any luck, that will provide some useful clues as to what exactly is going wrong.
I also wonder if you'd now have better connection stability using wicd instead of NetworkManager. You probably won't because I suspect the issue has to do with the driver itself rather than the connection manager, but it would be worth a try.
Sorry, I haven't been busy with midterms so I wasn't able to try those commands after the wifi disconnected.
So after installing 11.04, if I disable the security settings on my router, I can connect just fine. No more disconnection problems.
Here is the original output of lshw -C Network before connecting:

The only difference I see is that I managed to get an IP address =/
Could a problem be that my wireless card is also N (or Draft N not sure) yet this driver is only using the G band for some reason?
EDIT: Not sure if this information will help, but I've also tried connecting to my campus' Wi-Fi. It doesn't seem to connect to secured networks
