wireless

I have a dual-boot computer with Windows XP on one partition and Ubuntu 10.10 on the other. In Windows XP I can connect to a hidden wireless network (WPA-PSK AES) perfectly, and I was finally able to install the driver for the adapter on Ubuntu (RNX-N180UBE, hardware id RTL8191SU).

It works fine when I first boot the computer and log in, but then after a few minutes the network suddenly stops working completely. If I try to reconnect it, the network manager claims to have connected, but in actuality it's still down.

At some points, I have been able to connect to a public network even while the private network didn't work, but that eventually wouldn't work at all either.
