I'm getting ping spikes while playing DG.  I've noticed this a lotr during gameplay.  I'll be humming along at a great clip, pings at 100 or less to other players, like it was listed in the lobby, and then wham, the games stutters, and my ping to everyone else jumps to 1000 or more, then back to normal for a bit.

I've noticed this in DG alone, CoD4 doesn't exhibit this behaviour, nor does Supreme Commander, Company of Heroes, or the Half-Life series.  I have tried 4 different routers, WRV54G, DI-524, an older Belkin wired model, and a a TrendNet TEW-432BRP.  The reason I have them is for AP use.  I've connected directly to the cable modem, and experience the same behaviour.

I have no issues connecting to other players, in this regard, I am all set.  It seems odd to me.  I am currently on the phone with my ISP, WOW!, to see if there is an issue there, but I imagine they'll say everything is fine, go away.

I don't imagine there is an answer that addresses this direct issue(one can hope though), but I wanted to ask it anyway.
