This time when I installed some AVG anti virus upgrade. I'm sure there must be something simple I'm missing.
It looks like until I find the mystery fix my only internet access will have to be upstairs on the PC with it going stright into the modem, missing out the router althogether.
I might be better just getting a very long wire and trailing it down the stairs to the living room.
So I'll keep on guessing and hope I find the way back to my lappy (which keeps saying - Firefox can not find server at search.avg.com).
