The AT&T DNS Servers in Miami, Florida were down this evening. When you call their tech support phone number: 1-888-321-2375, they don't even answer. Here is my solution to get your DSL service back up and running.
1. Go to https://www.opendns.com/start
2. Go to your router at http://192.168.1.254 (2Wire)
(Your setting may vary depending on the router that you have)
3. Use the OpenDNS server settings.
I tried this and it worked!
Do you think I can get a credit on my bill?
