Most importantly, patch the driver station into this separate router with a wired connection, and disable the wireless on the driver station computer.
Make sure the radio on the robot is switched over to bridge mode, and that you are getting good and consistent Ping times.
When we do important demos, the separate AP is the setup we like to use. When possible, we avoid switching the robot radio over to AP.

This is exactly what we found with the robot radio at the Maker Faire in Detroit. There were numerous other robot radios running, plus a bunch of what looked like cell phone hotspots.
