Sorry - in addition to that, heres the outputs you requested in case I'm 
completely wrong:

from lshw -C network:
       description: Ethernet interface
       product: BCM4401-B0 100Base-TX
       vendor: Broadcom Corporation
       physical id: 9
       bus info: pci at 02:09.0
       logical name: eth1
       version: 02
       serial: 00:1a:a0:17:77:36
       size: 100MB/s
       capacity: 100MB/s
       width: 32 bits
       clock: 33MHz
       capabilities: bus_master cap_list ethernet physical mii 10bt 10bt-fd 
100bt 100bt-fd autonegotiation
       configuration: autonegotiation=on broadcast=yes driver=b44 
driverversion=1.01 duplex=full ip= latency=64 link=yes 
multicast=yes port=twisted pair speed=100MB/s
       resources: iomemory:dfcfe000-dfcfffff irq:20

from sudo iwconfig	

lo        no wireless extensions.

eth1      no wireless extensions.

(and therefore no iwlist)

Thanks chris,
