There have been 4-5 AT&T techs that have come in to address the problem, and have so far determined that the problem is between the main office and our home.

That being said, the level of service is simply unacceptable, and isn't getting any better.


This looks to be exactly the same problem I've been having, too.

Lots of timeouts.

It's ridiculous.
