Lagging in games, Network utilization is 1%. High Latency..what gives?

I've had this problem for awhile now. Whenever I join a game (COD: Black Ops, Left for Dead 2, BattleField: Bad Company 2, whatever), about 85% of the time my Latency is above 300ms. Sometimes it drops back down; only to shoot back up. This makes games absolutely unplayable.
