I have a one year old laptop which constantly shows media disconnected. I have uninstalled the Atheros AR5B93 Wireless Network Adapter which then of course reinstalls on reboot. There is a button for disabling the network which I have pressed and it flashes orange once every 4 seconds. I believe this means on, but haven't been able to find out for certain. ipconfig/all shows the media as disconnected. How do I connect it?
