Constantly getting dns errors. I have been on the phone twice trying to get this fixed. It happens on different pages. I have tried rebooting router and modem, and clearing cache and history. It goes away for an hour or two and then its back. I have a hn9000. My router is a linksys wrt54g2. Would upgrading to gen4 help? As it is now data seems to disappear. I am afraid I will always be out and it will cost a fortune. Thanks for the help.
