Try running the robot with a wired network connection and see if anything changes. If you have a way to scan for wireless networks (e.g. inSSIDer), see if your robot has chosen a channel already occupied by another access point.

I spent a little time last night helping a local team experiencing "glitchy" robot control. The Charts tab on the Driver Station showed lots of clusters of lost packets. It got better when the D-Link DAP was moved out from underneath a motor at the bottom of the robot, but the problem didn't clear up completely. We sort of correlated it with the direction the robot was facing, with packets disappearing more often when the radio was on the other side of the robot from the Classmate they were using for the Driver Station. Replacing the Classmate with my Gateway laptop resulted in nice, smooth control and very good communication. Putting the Classmate back brought back the problem.
