Wireless keeps disabling or stays disconnected (Realtek RTL8191SEvB)
- by jindrichm
I have Realtek RTL8191SEvB wireless card on Ubuntu 10.10:
$ lspci -v | grep Network
03:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8191SEvB Wireless LAN Controller (rev 10)
When I load its driver, according to the Network Manager it sometimes blinks with a list of available networks but it keeps disabling itself or it stays disconnected. So, I can't connect to any wi-fi network (which results in frustration).
The driver is loaded:
$ lsmod
Module Size Used by
r8192se_pci 509932 0
Looks normal:
$ sudo lshw -C network
*-network

So, does anyone know where the problem might be?
