My ipw(4) stucks at 100dBm as well. I think is is some kind of Intel
issue. Whereas "tcpdump -y IEEE802_11_RADIO -n -i ipw0" shows a more
correct signal strength:
22:45:25.639195 802.11: data: truncated-ip - 186 bytes missing!192.168.0.1.1900 > 239.255.255.250.1900:  udp 252, <radiotap v0, chan 1, 11b, signal 17dB>

BTW this is the AP somewhere across the street.
