Hi all,
I am having a problem with a specific web site that I cannot get to via
Firefox, IE, or Opera on XP and Vista. None of my three computers on my
network can open this one site and I instantly get a Address not found,
Firefox cannot find the server... message. If I plug my cable directly to
my main computer (not through the router) Firefox will find the site
without a problem. So, I assume this is a router problem but I cannot find
any settings that would do this. Any help would be appreciated.

What do you mean by cable, is it the wired connection or your ISP through a
Cable Network.
It may be a firewall thing or the site itself is blocking dynamically
generate IP addresses from your ISP netblock range, it's s possibility,
however, if you can access that site with your main computer without a
wi-fi connection it may be something else. Some anti-virus and anti-spyware
software can do that if you have it installed on other machines but not on
the main machine, but the site has to be known and registered in their
database. The procedure is usually to give you a warning but some can treat
the site as non existing which is a bad idea.
From experience, some sites do block IP address ranges at server level, we
had it on our server and found out that we were blocking thousands of UK
users using the same C netblock from Orange. That happened because one or
two spammers abused the system, their IP addresses got registered in the
spam database, but because they used dynamic IP addresses, the spam
database included any IP from their Orange ISP C netblock, hence anyone got
allocated one IP from that C block got blocked.

| And that of course included innocent users who are in the majority, it just
so happened they used the same C block. |

Thanks, Festprint.
That's a lot of information so it's hard to know where to start looking.
Yes, I mean my internet/tv cable service.
The blocked address is hit and miss. It will be unavailable for a day or
two, then be fine. I assumed it was the D-Link router since the problem
does not occur when I plug the internet cable directly into my main
computer. Also, all my wi-fi computers on the router have the same problem
at the same time.
So, still on the trail .... I wonder if changing to a different router
brand would help?
