Why does my internet cut out? The wireless network completely cuts out and flashes up error 324. I can't connect to any networks and the icon states 'not connected - firewalled'. It does this randomly when I'm using the net and is particularly bad late afternoon and every evening. It was doing it occassionally before but it is constant lately. It's driving me mad as I'm always half way through something when it happens so it is not that the the computer is left idle. I have to switch the computer and wireless off to restart, and sometimes it takes 2 or 3 restarts to kick in. Please help if you can!
