okay by accident i discovered NAS finally gave me some options
the NAS included in the WL500g serie keep its mouth shut..
to mention, NAS commands seem to differ a lot from version to version
Code:
# nas
Usage: nas [options]
-l LAN interface name
-i Wireless interface name
-k Shared secret
-m 0:Radius, 1:WPA, 2:WPA-PSK, default:Radius
-g WPA GTK rotation interval
-h RADIUS server IP address
-p RADIUS server UDP port
-s Service Set Identity
-w Cryptographic algorithm
The -l <lan> option must be present first and then followed by -i <wl> ... options for each wireless interface
