Linksys WRT54G router blocks one site

I'm pretty sure it's the router as when I bypass it and plug straight into the cable modem, the site is available. Also, I can't get to it from my wireless laptop either. I've looked at the admin panel and there seems to be no restrictions that I could see. Any suggestions would be greatly welcomed. TIA

 

Oops, forgot the error message.

Connection Interrupted

The connection to the server was reset while the page was loading.
The network link was interrupted while negotiating a connection. Please try again.

 

• Update: flushed my DNS cache, did a SW factory reset and then did the HW reset while checking the site each time, no go. lbmest pointed me to a possible solution here (post #13)

but I'm not too sure of what I'm looking at so I'll post some screenies. This is driving me nuts!

 

If your DNS Server had been pointed to 24.202.98.35 (the router IP address) that would have matched the poster's situation. It doesn't so there is nothing to change.
Sorry augie but it was just a possible fix.

 

Hehe, hey it was a good try and I appreciate it. What with people losing connectivity to windows.com or google etc., that's pretty serious. I'll update firmware next as that's about all that's left to try ATM, besides a clean install and even then who knows.:eek
