Hello, I am running a desktop system with XP (SP2) as an OS. I use Avast anti virus, Sunbelt Kerio Firewall and Spybot search and destroy. I connect to the internet via a belkin router / modem combination. (A Belkin ADSL2 + Modem with Wireless G router). I am hard wired to this. My house mate also connects to the internet using this router. He connects wirelessly. He finds that he is able to connect for about 20 minutes to (sometimes) an hour and then the connection fails. He currently puts this down to over heating. He tries a reboot - this occasionally works, but not always. Otherwise it is a case of turning the laptop off and leaving it for several hours. Obviously this is not the best solution. We do not use the network for file sharing / gaming. It is only to provide us both with internet access. Any thoughts or directions to posts that have a similar theme would be a great help. Will.
