Sometimes when loading pages in firefox I get a server not found error. If I refresh the page then it loads. This doesn't always happen but it happens enough that it gets annoying. How can this be fixed?

By any chance does it happen only when connected wirelessly? If you connect to the network via a cable is it much more reliable? – DaveParillo Jan 14 '10 at 23:28
I'm not using a wireless connection. I'm directly jacked in. – Phenom Jan 22 '10 at 20:40

This is a very hard one to answer - It can really be a number of issues.

As you said it is "Server not found", I am inclined to believe this could be issues relating to DNS timeouts.

Try changing your machine (or routers) DNS server to Open DNS ( or Google DNS ( /

opendns will also protect you from dns poisoning... – barraponto Jan 15 '10 at 13:13
I noticed with Google DNS pages load faster and I get the error less often, but the error still does occur sometimes. – Phenom Jan 22 '10 at 20:40

The problem could lie anywhere:

  1. Between your computer and your connection to the outside world.
  2. Between your router/cable modem/whatever and your ISP.
  3. Between your ISP and the main trunk.
  4. Between the main trunk and the target site's ISP.
  5. ...

Well you get the picture.

You only have direct control over 1. so double check that the connection is sound. As it appears that the problem is not limited to one or two sites (though you don't say this explicitly) that would tend to rule out 4.

However, as the problem could be either physical or software it's difficult to offer any firm suggestions. See if you can get your ISP to test your connection - there might be an issue there. You could also try rebooting your router - you never know it might clear the problem (at least for a while).
