!It's not clear whether the connection is 'dropped' at all if it still
!says 'associated' - does it always still report being associated when
!this occurs?
!
!Does anything in /var/log/messages indicate interface wi0 being brought
!DOWN and UP when this happens?  Are you running any scripts or programs
!that might do any other configuration of wi0?
!
!Is 192.168.1.102 a static address, or assigned to you by DHCP?
!
!You've given us few clues about your setup, it's unclear whether you
!control the access point you're connecting to (regarding what people
!have suggested about choosing another channel than 1)
!
!What do 'grep wi0 /etc/rc.conf' and 'dmesg | grep wi0' have to say?

!Sounds similar on the face of it .. was that resolved, Gary? 

Yes, now that he notes that the "inet" line is "completely missing!",
it is the *exact* same problem.

And, no, it is not yet resolved.
The last time I had the client's notebook connected to our AP,
it was exhibiting the same problem.
Connected to the wired Ethernet port on device fxp0,
it behaved perfectly.
