Hi There.
Someone knows why the Freebsd wireless Access Point work so bad on 
Freebsd 5.1??
I try lot of thing but I couldn't make it work fine,  the wireless card 
crash the connection , the speed is very slow whan is working, is 
imposible to use. but same setting , same wireless card, work perfect on 
Freebsd 5.0.
I tried different computer, adapters, settings, wireless card, but 
always is crap on Freebsd 5.1 current or 5.1 realese.
May be I need an Special setup?
