回复：没说什么无线网卡

Thanks. Seems it is not. The info is here:

Network controller: Broadcom Corporation BCM94311MCG wlan mini-PCI(rev01)
Ethernet controller: Broadcom Corporation BCM4401-B0 100Base-TX (rev02)

BTW, I really don't anything abotu linux, otherwise, i needn't bother to ask here. I did Google, haven't got anything useful/understandable to me.

Any help, thanks!
