I have been losing connection for some time now. Rebooting seems to bring it back most times(sometimes a couple reboots-power cycling modem dose not). I have RoadRunner Central NY as myISP(they are of no help-"everything looks fine on our end"). I have a direct connection to modem(Motorola SURFboard SB5101). I have WinXP Pro SP2(with all updates), browers is IE 6(with all updates). Running Windows Firewall and I have Fix-It Utilities running it's virus protection program(TrendMicro engine). I can go for a time without losing connection and then there are times where it will drop right away. I sometimes receive DNS server not found error. My LAN is a Broardcom NetLink Gigabit Ethernet(onboard and with the latest drivers) I have run HiJack This and the log is:

I hope someone can help on this problem, Greg T

P.S. I have run diagnostics on the LAN and it shows no problems.
P.S.S. I have also installed a PCI NIC card with the same connection problems. Thanks in advance for any help, Greg T

Greg T,
I know this might be a stupid question but have you cleared the browsing history, Temporary Internet Files, and Cookies. Also you might have a memory leak this is when a program uses memory and when its doen don't return it to freed memory. Hit atl+crtl+del then choose task manage and then processes then if you click CPU or mem usage it will show you the amount each app on your computer is using this can run and update as you use your computer let it run while you surf the internet and see if anything uses a ton of resources.
