I have recently had to replace my wirelss modem, due to an electrical storm. The trouble is now the new modem won't recognise that there is an ethernet connection between my computer and the new  wireless modem/router. The cable is physically connected to the modem but the port light is not on. There is nothing wrong with cable as I have PLUGGED in my old non-wireless modem via this cable and it has worked (I am connected to the internet now using this cable and old modem).
I gave tried everything from system restore to a date pre-electrical storm,updating drivers, resetting and manually reconfigering the modem. On a couple of OCCASIONS I have been able to get a signal (the port light is on and I can connect to the internet) only to return to my computer and find that the port light has gone off and there is no longer a connection. I thought that maybe the modem was not compatible with my computer for some reason and so changed the brand (Netgear to D-Link) still no joy. HELP!!!! Quote
