2 days ago my wifi Internet connection disappeared along with all the other wifi networks around me that were available. All that it says now is 'no connections available' with a little red cross next to it. I tried a wired Internet connection but nothing, still the same message in the bottom right corner when I tried to connect to a network, there just aren't any there at all. I have a Sony Vaio, the networks switch is on and there is another laptop and 2/3 other phones connected to the wireless we have and all working fine so it must be my laptop. Anyone have any ideas?
