I tried to read the man pages for the wi, but perhaps it is just a little outdated or wrong because: my cmd is wicontrol -p 0 -C 1 -q your_ssid but: -i iface -p port_type Set the port type for a specified interface. The legal values for port_type are 1 (BSS mode) and 3 (ad-hoc) mode. In ad-hoc mode, the station can communicate directly with any other sta- tions within direct radio range (provided that they are also operating in ad-hoc mode). In BSS mode, hosts must associate with a service set controlled by an access point, which relays traffic between end stations. The default setting is 3 (ad-hoc mode). so -p 0 is not a valid choice :-) !!!!! -i iface -C Display the cached signal strength information maintained by the wi(4) driver. The driver retains information about signal strength and noise level for packets received from different hosts. The signal strength and noise level values are displayed in units of dBms. The signal quality values is produced by sub- tracting the noise level from the signal strength (i.e. less noise and better signal yields better signal quality). This is a display option , but I use it to set :-) 2) I have two xircom wl card so I can try to use 2 laptop simultaneously to see what happens :-) Best Regards, Gianmarco Giovannelli , "Unix expert since yesterday" http://www.gufi.org/~gmarco To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
