 From the attachments:

01:01.0 Network controller [0280]: Broadcom Corporation BCM4306 802.11a Wireless 
LAN Controller [14e4:4321] (rev 03)
        Subsystem: Broadcom Corporation BCM4306 802.11a Wireless LAN Controller 
        Flags: bus master, fast devsel, latency 64, IRQ 2
        Memory at 40004000 (32-bit, non-prefetchable) [size=16K]

Is this really a 5G-only card? Everything I could see about the WRT160N seemed 
to say that the routers are 802.11b/g/n.

In addition, we really needed more BCM43XX confusion. Is a BCM4306 an 802.11b/g 
with a 14e4:4320 chip, or this one?

Broadcom is really easy to hate!
