As mentioned below, the target log was empty.

I don't know what "CHANNEL" is. > > Also, if you are using dhcp, look at /etc/dhcpd.conf in the target machine. Its not that sort of thing, It is a Vigor 2910G router. Its DCHP is working and it has a log I can watch. Remember that my problem is on a dual boot laptop. I run Wireshark in each partition, watching the WLAN. I try the same connection in the WinXP partition as in the FC7 partition. WinXP: Wireshark and Vigor show plenty of activity; quick connection. FC7: Wireshark and Vigor show exactly zero activity; no connection. I note that the blue wLan light on the laptop comes on in both cases. Thanks for any help you can provided. Mike.
