I was playing BF2 and noticed some network lags that occurred at intervals. I have checked the network card and it normally runs at 3.160kps. Periodically, it will plummet to 1.5 kps. I checked the Vista Resource monitor and didn't see anything unusual except an instance of IExplorer on an address named saruman which I did not recognize (could be DNS).

It's a wireless connection to a Westell 327W with an RAlink Rt61 Turbo card.

Any ideas?
