Toshiba Satellite M40. Problem: Wi-Fi button has to be set on/off each time to activate wireless network connection. I never had this problem until this morning, what could cause this problem? My laptop is one and half yr old, normally i just leave the Wi-Fi button to on. But now each time when i shut down/restart, even though the Wi-Fi button is on, there is no light and i can't connect to Wi-Fi unless i switch it off/on. Anyone faced this problem before?
