Hi I'm on XP and have had wireless broadband for ages until yesterday morning it suddenly wouldn't connect. It can detect the network and other networks in the area but cannot connect to the internet. I've done the following things: Turned the router on and off. Pinged my IP, which came back with this: Request timed out four times, Packets sent=4, Received=0, Lost=4 (100% loss) Is something blocking it? Could it be a trojan or virus? I've got both Kaspersky and Adaware, currently scanning, but I'm not an *****, I never download or click on anything dodgy, I only checked my email on friday night before turning it off. I don't know what could have changed overnight. What can I do? Thanks.
