I have a Toshiba Satellite A105-S4211 whose on-board Ethernet port was connected to the Netgear wireless router. Yesterday, due to heavy thunderstorms/lightening, my netgear routers power adapter stopped working. Laptop was shutdown and the power was not connected either. Still, the on-board ethernet port disappeared from the device manager and I couldn't get it working at all. I did a complete reinstall from the cd which came with laptop and no luck either. Wireless works but my wireless router power adapter dead. My internet modem has only ethernet and my laptop ethernet port is dead.... any suggestions?
