My home network consists of a cable modem (Comcast is ISP) to an SMC router and is all on Ethernet cabling. The 4 computers all run WinXP SP3 and Norton Internet Security 2008. About two weeks ago we first noticed that it is now either impossible (Windows cannot display &.) or extremely slow trying to access the Monster.com site past their initial home page. Other sites, including those that require a log-in, seem to be OK. At Comcasts suggestion, I rebooted the modem & router without success. I also bypassed the router and connected directly to the modem also without success. Of note, a laptop running Vista with McAfee antivirus was OK on this same network. A Mac with OSX did not work (was sloooow!). I took one of my machines (XP SP3 & Norton) to a neighbors running on Comcast cable, plugged it into that network and it was fine. Using my XP machine, the Vista laptop or the Mac laptop on a borrowed neighbors wireless network also all worked fine.
I cannot logically find the common problem. If it is my modem/router, the Vista machine should not work. If it were my XP/Norton settings, why would the Mac also be slow? If it is my XP/Norton, why would they be OK on a wireless connection or another wired network?
Thanks for any ideas.
