My computer has started telling me it can't detect my modem, which is a BT Home Hub. I called the company helpline and we tried altering a few settings but no joy. They said it would either be my ethernet card or network drivers or the hub itself was broken. How do I tell where the problem lies? There are 5 lights on the front of the hub which should be lit, but the last -labelled Data- no longer lights up.
Please help!
