Hi All - I am scratching my head in frustration wondering why my Atheros network adapter won't switch on. I have disassembled the laptop (Samsung RV510-A01) and checked all connections and they seem fine. I have updated drivers and when I decided to uninstall the adapter, after restart Windows (Vista) does recognise the adapter is there...but somehow I can't seem to get the adapter/wireless LAN to switch on. HELP!!!!!!
