major ping fluctuations in swat 4

[elitebear4]

alright, well let me lay out some basic info about my internet connection. i recently changed isps and so far have a network that is atm, unprotected. when doing basic things, such as web browsing or using AIM, everything seems normal and my modem lights dont blink much. everything is fine. however, when i play swat 4 online, my modem starts blinking furiously and my ping is in the 300's. my modem acts like its gonna explode. what the hell is going on

Games aren't very bandwidth intensive but packet intensive. This means that modems will blink more furious then normal since most respond to frames or packets to show utilization.

This 300 ping, is this across many servers?

yeah

check for spyware, get encryption, RIGHT NOW. you should never have an open network. NOT A GOOD IDEA AT ALL.
What connection are you on ? Dial up or DSL/Cable?
