Interesting! After all the updates and diags I disabled my Windows Firewall (which did have GW2 allowed) and installed Zone Alarm (free) instead. Suddenly I have my connection back.
Mysterious.
This same problem happened to me starting between 4 and 5pm EST 11/12/12 after many hours of playing up to that point. I’m able to load the client, log in, select my character, and get maybe 10 seconds (if I’m lucky) of actual connection before everything drops. I have to force an exit of GW2 before my internet will come back.
