Hey guys I need some help here. When playing Halo online through my PC, I create a game or server using my Cable connection of at least 1g. with a Pent 4 and 1.5ghz. While playing the game my ping shows up at "0" but everyone else who joins my game shows a ping of "200-500". They also have complained of a lot of Lag and choppy game play while my game play is bitchen. Other than changing the settings at my end, ie: resolution, is there any advice you guys can give me ?? Thanks

It might just be your connection...
If your upload speed is:

128kbps - You can only play with 1-2 players max w/o lag
256kbps - 3-6 players max w/o lag
384kbps - 6-8 players max w/o lag
768kbps - 10 players max w/o lag

Anything above 10 players will be unplayable unless you are running a T1 or T3.

Also your gameplay will be "bitchen" because you are the Host, thus you have 0 ms ping, and no lag at all.

Generally with cable internet access, your upload speeds are significantly lower than your download speeds. You may get one mb down, but you'll most likely never see that up. 128kbps upload is more like it for residential service.
