Good morning, Sam.  I just disabled encryption on my router and
changed my rc.conf to
ifconfig_wlan0="DHCP ssid virus2"
and as you probably knew, it works flawlessly.

Now I have to ask, what I can do about wep that works on my Sept 20
and earlier kernels and doesn't work on my recent kernels?

Thanks,

ed
