I am using wireless card rtl8192se. The official site of realtek provided a driver that supports kernel up to 3.2.x but recently i upgraded to 13.04 so i cannot use it.
Initially the driver in the kernel works find but after a while it start disconnecting after a few minutes.
The signal strength shown in the panel drops from 4/5 to 2 yet if I click open the menu, the strength remains. In the same time, network slows down drastically (from 100+kb/s to 100b/s). Only if i disconnect and reconnect will it start to work. but after a few minutes, it appears again.
This is not a new problem, but I cannot find a solution to that, especially with kernel 3.8.x
