FreeBSD Client won't associate with WAP

[Dan Hassler]

I must have missed something very simple.
Have FreeBSD 4.8 client with Linksys card. Intersil Prism 2.5 - not the 
WMP11 with the Broadcom chip.
dmesg.boot shows wi0.
ifconfig wi0 shows everything fine but no signal
wicontrol -L lists my AP as available.
AP shows client error if I deny access to client's MAC but does not show 
a connect or any errors if I allow the client MAC.
Running in infrastructure (BSS) mode. Authmode shared. WEP enabled.

Is there a specific command to instruct a client to associate with an 
available AP?

Thanks,

DH
