    ok I came home from work and found that the network card of 2 computers connected to the router will not work all get is limited connectivity, The router will not detect the modem connected on internet port. Tried connecting the modem to my network card same issue limited connectivity. Connected the modem to a xbox 360 and it worked fine. from a spare computer transferrd a network card and was able to connect directly to the modem. Is it possible for the router to damage the network cards

    If you had lightning, or something failed in the router, it might be possible to get damage on downstream network cards. In your scenario, it rather sounds like, if it was lightning, it got picked up by one of the network cables between the router and the PCs, which took out the LAN switch on the router and the 2 network cards.

    In network cards, one of the wires is grounded to the PC's ground, which provides an electrical path for lightning to ground. (I have lost a number of serial ports in this way).

    If you don't have/had lightning, a hardware failure in the router could probably have caused it.
