Some websites inaccessible via wireless network

Hi

Yesterday, I suddenly found that I was unable to access certain websites through my home wireless network. I don't always access these sites very frequently, but I did access one the day before without any problems. 2 examples of sites I've been unable to access are click here and click here, but some other sites (including this one) seem to be permanently loading. My status bar here currently reads "Waiting for view.atdmt.com...". When the site is entirely inaccessible, my browser tries to open the page for minutes without making any progress, then I get a message saying:

"The connection was reset - The connection to the server was reset while the page was loading. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web."

I'm running WinXP SP2, with a Netgear DG834G router, and using Firefox as my browser. I've tried using IE (*spit*), but have the same problems. I've got McAfee installed, but I don't think that's the problem, as I've found that I'm able to access these sites perfectly well if I use another unsecured wireless network I detected in the area. (Yeah, I know, but it was just for the purposes of diagnosis!)

I've switched PC and router off and on again plenty of times, I've deleted cookies and temporary internet files, but nothing seems to work. Any ideas?

Further update:

I've run a tracert for the Halifax site, and got the following:

try changing the 'MTU' setting in the routr to 1432

Have spoken to Orange (my ISP) about this and it is a known issue - outage is being blamed. Changing the MTU makes no difference. They have escalated my problem to level 2 tech support who should sort out within 24 hours

Setecio, I've tried reducing the MTU setting, but no joy there either.

I'll get in touch with my ISP tomorrow and see what response I get.

  User-1233348 12:05 27 Jan 2008

IPBoy - who is your ISP? Just wondered whether the problem is specific to Orange or is it affecting other ISPs. Some of the sites I can't get include click here and click here

  User-1233348 15:00 27 Jan 2008

Just to let you know Orange have resolved outstanding issues - all sites now accesible

  IPBoy 21:22 27 Jan 2008

Problem now resolved. Spoke to my ISP (AOL), who were surprisingly helpful, and solved the problem in a couple of minutes.

The problem was, as Setecio suggested, MTU based. I don't know why my previous attempt to solve it by reducing my MTU didn't work (I tried that before I even posted here), but everything seems fine now.
