Hi and sorry my English.
If wl500w not supported, you can control it with cron daemon and wl command (wl radio on / wl radio off). You need create two script for enable/disable wlan function.
/opt/wldisable
/opt/wlenableCode:#!/bin/sh wl radio off
and need configure cron daemon for enable/disable time. See it macsat.com.Code:#!/bin/sh wl radio on
Bye, George
