wireless network disconnects randomly.
Dear forum,
I'm using slackware 12.1
kernel 6.24.5
wireless usb card: level1 WNC-0305USB.
My network (internet) works fine, but after random (or pseudo-random) time interval it disconnects.
I upgraded to kernel 2.6.26, but the problem stays.
The wireless network works fine under windows XP in the same computer.
any one can help me on this one?
