Lightning Strike and electrical power surge

  1. Jun 14, 2008 #1
    Recently, lightning hit near my home (as best as I could tell, not my home directly) and caused considerable damage to my home computer. I have a wireless network with 2 desktops.....one direct wired using ethernet cable and the other using a NIC card. When the lightning struck, my wired computer lost the modem, the router, and that was it! My wireless computer lost the NIC card (it was blasted into many pieces inside the tower) and my surround sound speaker system. Both CPUs seem fine.......and really all other components in the house are fine. I'm thinking the CATV line got struck and surged into the modem and router. BUT WHY DID THE WIRELESS CONNECTED COMPUTER HAVE DAMAGE, ESPECIALLY THE NIC CARD BEING BLASTED APART? Just wondering what was going there? Any insight would be greatly appreciated!

    The computer's internet connection was wireless, right? I mean, was it plugged in to the power source in the wall?

    Both computers (gateway and remote) were plugged into surge protection power strips.

    Sorry for digging it up. I would also like to know the answer to this one.

    After several conversations with numerous electricians and academic professionals, I've yet to ascertain a definitive answer as to the occurrence of the electrical surge!

    Hi CM

    You were using NIC to connect the two computers. If there was no damage to the motherboards, then that would mean that the problem happened with the internet cable carrying the signals.
