we have 2 computers connected to a Netgear 834GT router. ( used to use a Draytek 2600, had some problem ) Both machines have XP SP3, all updates ok. They both have AVG 9, again all updates ok. Sometimes when opening IE it doesn't connect at all, not even to the IP of the router. Just says try to connect to..... Other times it opens fine and but you try and open a new tab it will not connect the new tab but using the original tab is still ok. I have tried opening IE with add ons disabled, no difference. I have repaired the winsock, tried turning off the XP firewall, all no difference. If it doesn't connect all I can do is close IE completely and wait a few minues, then it will probably open ok. Any ideas, I really don't know what to try next. Happens on both machines, identical problem.
