I was wondering if anyone else was having issues with DNS and their AT&T service? This morning all devices in my house stopped being able to browse the internet. Cell phones on Wi-Fi said there was an issue with the internet on the profile. PCs would try to load a webpage, but all we get is for example looking up microsoft.com and then the site cannot be reached. I contacted AT&T support and they are blaming it on the residential gateway. I am not confident that this is the answer. I changed my DNS settings to use Google's public DNS servers and have had no problems on the devices that were changed over while the devices still using AT&T DNS servers cannot connect. Unless the DNS resides within the gateway, I am not sure a new gateway will fix the issue.
