Russell,

Here is the output of iwconfig:

robin at moose:~$ iwconfig eth1
eth1      IEEE 802.11b/g  ESSID:"KP4983"  Nickname:"Broadcom 4311"
         Mode:Managed  Frequency=2.437 GHz  Access Point: 
00:15:E9:69:36:FF           Bit Rate=24 Mb/s   Tx-Power=18 dBm           
RTS thr:off   Fragment thr:off
         Link Quality=88/100  Signal level=-46 dBm  Noise level=-69 dBm
         Rx invalid nwid:0  Rx invalid crypt:6  Rx invalid frag:0
         Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Noise level seems to be a bit higher than the signal level...do I read 
that right?
