Hello All,
I have browsed the forum looking for the same problems but to no avail I could not find one.

The problem I have now is after a bad thunder and lightning storm I no longer have a working wired connection on my Toshiba A300D laptop. I have tried:
1)switching cables
2)switching power off and restarting
3)Looked under device manager under network and could not find LAN symbol, only Atheros wireless network adapter (which still works)
4)scan for hardware changes

All of this has come back negative and I am stil no closer to resolving the issue. On the ethernet port it still lights up in green and orange. I am hoping that I am just missing something simple instead of replacing or adding an external pci.

I would

a. Uninstall the network drivers via Device Manager...then reinstall them.

b. Reset the router by powering it off and then on.

c. Be prepared for the possibility that the NIC is dead. Happened to me with a laptop eons ago, same situation (nearby lightning strike).

Thanks for the tips however I can't even

a) uninstall the network drives because they do not show up

B) tried turning off the router and powering back up

c)How do I find out if the NIC is dead? It has lights on still. I just dont have anything under device manager such as LAN or network adapters except wireless adapter driver.

Since it's a laptop...the only way (I know of) to verify a nonfuctioning device...would be to temporarily install a cardbus NIC and see if that works.
