Did you mean you could play normally on one machine and not on the other, or are you having that problem regardless of the machine?
Problems with ping could have several reason, first thing to do is to isolate the problem before trying to solve it, instead of trying a dozen of random solution.
First checking for sure is to know if the problem is on your computer or on the SE server. This can be easily done by using different computers and/or different network.
So, try first connecting the game using your default internet. If its no good, try routing your cellphone internet and see if it change something. If you have another computer with the game installed, or another friend thats playing, you can see if you can replicate the problem.
Needless to say, if you can isolate the problem to your computer, you surely can do something to fix it. If regardless of computer or network the problem persist, then its a server problem and there is nothing to do aside waiting.
