A couple of years ago I had Uverse and had a lot of issues connecting to VASSAL. I don't remember ever solving the issues I had, and when I switched to cable everything worked fine.
Problem is I just moved into my new home, and the cable connection isn't reliable, so we might have to switch back to Uverse....
Does anyone currently have AT&T and play on VASSAL regularly? Hoping the issues I was having have been resolved.
Here's a thread on it but it died last year:
