What is causing my laggy online play?

I am playing this game, Popkart, and I keep getting disconnects and just overall slow online speeds. It is causing some in game problems as well as the disconnects. I don't run any other program than this application when I play it. Do you guys reccomend any possible solutions? Two weeks ago, I was playing the exact same game fine, with no disconnects whatsoever, so this problem is very puzzling to me...oh yeah should I try the ol' unplug router and modem and plug it back in? I remember I did that once and it didn't turn out so well last year. My router actually just stopped working after I tried that in 2006 and had to replace it.. anyway advice and replies would be appreciated...

 

Isn't that a Chinese game? I don't want to seem racist or anything, but online Chinese and Korean games almost always have horrible networking problems... outside of China and Korea, at least. :/

 

believe me...
they don't have a "horrible" networking problems. everyone uses faster internet at korea than us, way faster since everyone there is like internet game players .i dunno about chinese.

okay to the topic...
plugging the router and modem back in shouldn;t breake your router: i did that tons of times but still live. it is the first way to solve the network problem
second is the router settings: check on the port forward settings, built in firewall, and enable the dmz (enable dmz only during game play since it is little unsecure against viruses)
finally, if you have firewall running.. disable it or quit it completely.
try those three...

 

To nunka: Nah, I was playing this game in China and it was lag free in most places and I wasn't experiencing any lag with this game couple weeks ago..
Thanks for the advice someone, i will try them out later..
