This is the log of the laptop.  As mentioned below, the target log was
empty.

How do they look?  I don't know what "CHANNEL" is.

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.
