I'm having this problem too, as is my boyfriend. The game was working just fine for both of us until two days ago (20th September). My boyfriend managed to log in twice, but he was incapable of moving.
We are in university accomodation, and all of the new students moved in at the weekend, who are connecting to the university network.
For good connections, column 1 and 3 have values around 500 kb/sec (outgoing/incoming), column 2 has values around 20 kb/sec (transfer rate). If the values in these columns is less than what is expected you may have filtering or blocked ports either on your personal network or from your ISP.
post the results of the nettest and traceroutes. and the rest of the imformation. Can not say what might be the problem with out data.
internet is constantly changing, route have problems equipment and software get changed , weather and other factors knock paths off line or degrade them.
ISP constantly changes thier traffic manaegment setup.
firewalls and antivirus may reflag patched software as a possible threat and block.
