ping..

ITs your internet. Dc and reconnect ur router, try a disk defrag. maybe ur ISP is working in the area. could be any of there.

Well, this is weird subject because it CAN be your internet connection or it CAN be the connection with Crossfire.

My ping was 92 for about 4 months and then went up to 120-150 for two weeks and then after the patch my ping was 72. I used the same server throughout that time. It was NOT my internet connection, it was my connection with Crossfire, and other people seem to be experiencing this problem as well.

As the others stated, try seeing if it is, in fact, your modem and/or router. If not, then just deal with it for now. You can try calling your internet provider and ask them to come out to test your equipment and connection but a fee may be applied to your account.
