I am losing my internet connection every 10 or 15 minutes and when I run the troubleshooter, the error I get is "The DNS server isn't responding". It is down for 2 or 3 minutes and then comes back up again.
I have reset the router (Dlink DIR-655) but it doesn't help for long, if at all. I have tried the flushdns/registerdns, etc ipconfig commands, but nothing is helping. I have Windows 7 Home Premium 64 bit. Any help is greatly appreciated!
