My Dell won't connect to any wifi networks this morning, nor will it make a connection to the BT Hub3 by Ethernet. I have a built in Intel N adapter, which I tried all the usual steps with before disabling it and trying a BT N wifi dongle; no connection there either. The Hub is connected with an excellent signal but the laptop won't recognise it. All my other computers connect as usual so it's not a router or Infinity question. So I disabled my firewall and set IE9 to the lowest security setting - nada.
This is definitely an isolated problem on the computer and not the network. Just wondering what else I can try. The only thing I can think of is a System Recovery to yesterday, when everything was fine. Strangely, IPconfig reports all the correct addresses at ethernet and wireless, even though there's no connection.
