My pc has been connected to the internet through a wifi(802.11g) network now for 3 months and iv had no problems up til today. I was chattin on msn messenger and it suddenly lost its connection to the network and cant reconnect since. The windows wireless network tool says the network has a full signal but a utility i got with the wireless adapter card shows the signal jumping from no signal to full. i hav another pc downstairs which uses a ethernet connection and it works fine so its not a problem with the ISP. the WiFi connection is open and my house is a long way from other buildings so nobody could be leaching off my network. I havn't moved the router or got any new equipment lately that could be causing interference either. Any one have any idea whats wrong?
