    Unidentified network – no valid ip config – can’t get it to work!

    Hi. I disconnected the ethernet cable from my router to temporarily kill internet access, but when I reconnected the cable it no longer worked. The network now shows up as “unidentified” and the troubleshooter says “Ethernet does not have a valid IP configuration”.

    I’ve checked all the network/adapter settings and can’t see anything wrong. I tried a new cable in case that was the problem but that didn’t resolve it. I’d read somewhere that the n/w adapter on the motherboard might have become faulty, so I’ve put in a new pci ethernet adapter. That’s showing exactly the same problem – unidentified and no valid IP.

    I’ve done everything I can think of but with no luck. Can anyone suggest anything? Thanks

    ps: I can connect ok using a usb wi-fi adapter ( I just prefer to use ethernet).
