Comment 26 for bug 945379

When I run

sudo lspci -v -s 02:00.0 |egrep -v 'Serial Number'

I get the following;

02:00.0 Ethernet controller: Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) (rev 01)
 Subsystem: Askey Computer Corp. WLL3141 (Toshiba PA3613U-1MPC) 802.11bg Wireless Mini PCIe Card

Don't know if this will help.
