Here is how to disable AT&T's 'DNS Error Assist' service on your account. So my bet is you also don't know that by default AT&T has taken upon itself to forcibly inject it's own DNS server (as the router) with the latest round of firmware and unless you TAKE ACTION TO OPT-OUT, will intercept your DNS queries via new changes in router firmware pushing out the router as DNS server.ĪT&T's VERY HIDDEN 'helper' redirection for DNS that YOU MUST OPT-OUT of is named 'DNS Error Assist' which causes this unwanted behavior.

Now, what REALLY took friggin digging including phone calls to finally find an engineer to let the cat out of the bag is why the '104.239.207.44' address? Where is that coming from? In almost every case, simply preforming a IPCONFIG /RENEW right there and again performing the /ALL, will then correctly show that YOUR DHCP SERVER'S ASSIGNED DNS SERVER is now listed. You will see SPORADIC mis-resolutions of EVERYTHING to that 104.239.207.44 address if their crappy router happens to hear your PC's DHCP request - EVEN IF ANOTHER DHCP SERVER ON THE NETWORK assigns the ultimate address.ĭo an IPCONFIG /ALL on the PC in question, and look carefully only at the DNS SERVER line.and note it is wrongfully THE ATT ROUTER (192.168.1.254 in my case)!.
