My internet connection after an hour or so stops working, as if it times out or something, even though up to this point it is fine. If I try to visit a web page after this happens I have to reboot to get it to work again. Oddly, it appears that sites I'm currently on I can still visit, but can't visit a new site. It seems to be a problem with the pc, because my other computers that connect to the same router aren't affected. Firewall (ZA) is correctly set-up, Vista Home Premium.
Any suggestions?

Sounds typically like you have a virus infection, what AntiVirus software are you running...

Is your connection to this computer wired or wireless? Tell us what kind of router you have as well. Sounds like you have your internet settings on that computer set up wrong. Check in your "Network Connections" from your control panel if you have a "Bridged Connection" This is typically one I find on a lot of people's computers. The 1394 Connection and the Ethernet connection become bridged.

No, I can rule out any malware connection, that's the first thing I thought off.
Wired, via ethernet. Also, like i've said the internet works fine, until a random time when I can no longer surf. According to Vista's internet diagnose and repair option, there is a DNS issue (which I believe to be rubbish).

I have rebuilt 2 pc's recently where the dns was botked, which was a direct result of an infection. The only fix is to reinstall the OS.

I've been informed that I could try and reinstall the firewall. I'm also thinking that perhaps some of the pre-installed software on the pc may be conflicting with something somewhere.

Once it goes wrong, type nslookup in a command window. This should tell you which DNS server you're using and you can type domains such as google.com to test its operation. Compare with other PCs on the same network and see if there's a difference.

Here's something you might want to try:
* Goto the Start Menu and look for Network Connections, if its not there, check under Control Panel.
* Double-click your network adapter and hit the Properties button.
* In the list box in the middle of the Properties screen, select "Internet Protocol (TCP/IP)" and hit the Properties button.
* See if the "Obtain DNS server address automatically" option is selected. If it is, you may have a problem and should set your DNS manually.
If you need to get your DNS IP, simply open up the command prompt and input the following command: ipconfig -all
Your DNS should be in there somewhere. Keep in mind to only do this when you can connect to the internet.
Hope that helps. :thumb:
However, a simpler method might be to refresh your NIC settings using the following commands (in the command prompt, and in order): ipconfig -release & ipconfig -renew
