It certainly appears that there is a sytemic problem. But the data support team is unaware of it. I spent 2.5 hours with them last night. Escalated 4 times to a senior tech. He was unable to figure out the problem. I am a 2 year user without any past problems connecting. For the last week the PC Client software has been able to make the connection for maybe an hour a day. I continually get the "server not found error" occassionally, I get an "invalid sign on" I've installed and reinstalled both the PC and wireless device clients twice.

Tech had me email him an error log but he implied it's on my side of the connection. Given that I was able to log in for an hour or so after I got off the phone with him...I don't think so. 

Anyone from AT&T monitoring this forum?
