Every day I lose my connection to the internet. I have a wireless network. The PC's can still see each other and at times one of the PC's can still access the internet and the others cannot. When I try to diagnose the problem I get a message saying "cannot communicate with primary DNS". Sometimes turning off my firewall helps. Can anyone help me with what I may be doing wrong. Thank you.

Is this every day about the same time? Perhaps a neighbour that comes back home and turns on their own wireless network, causing interference?

Try changing the wireless channel to start with...

No it happens at various times of the day. It is not only when the computer "sleeps"

Check for interferences from other WiFi Access Points anyway...

First check on your PC if there are other wireless networks present. Then follow the link I recommended before, select a new channel and update this on your router. Most channels in New Zealand are set to 11 - check what's in your router and follow the article's instructions to select one that doesn't conflict with the current setting, then change it.

There are no other wireless networks showing in my network connections. I changed the channel but no different but it seems like it might be a firewall problem. As soon as I turn off the firewall and automatically assign a new IP address it works. Once the firewall is back on and the pc restarted I am back to the same problem. I run Nortons 360, do I need to change some settings there?

Is this a new install? Perhaps check the Firewall rules to see if the DNS server is not blocked by mistake. Other than this you might have to check all blocked applications and ports...

Quic Broadband

No it is not a new install but the problem has only recently started happening. I thought it was my new router but I reinstalled the old one and have exactly the same problem. I will go through my firewall settings one by one and see if I can find anything. Thanks
