I've just spent the last 4 or so hours troubleshooting my puter... at first I thought it was a virus attack, then thought the satellite modem had failed... in the end I'm pretty confident its the router!
Bypassed it and everything is rock solid. Plugged it back in and can't even get to the admin page in the router... time for a new one. No network drives, wireless or network printer for me till the new one arrives.
