Bridge resetting

On our prototype bot, we have the strangest bug. The robot runs fine when tethered, and it stays connected through the router as long as I don't turn on the motors. But as soon as I run the motors, we loose robot connection and then it comes back a half second later. Has anyone ever had a resetting router? Any ideas how to fix it? I'd be happy to provide any other information you think might be useful.

ADDITIONAL INFO:

- When we built this we didn't have the power converter, so our bridge is connected directly to the 5V plug meant for the camera. Could that be it?

- I made a video of the problem: https://www.youtube.com/watch?v=8aiRn_k7N_Y (you can see the drivers station and hear the motors).

- I tested the plug that goes into the bridge with a multimeter (when it's out of the bridge), and even when I'm jamming the motors it doesn't vary from 5.08V

- The power light on the bridge turns off when the connection drops

- There are no chain runs on the robot, so the gearboxes are not taking any load

- Battery voltage reads 12.5V on a multimeter, I charged it very recently.

Thanks,

- Alex
