With the motor removed, do you still have a short to the frame?

How is the dlink wired? Is it going to the proper port on the power distro board and through the 12V-5V regulator?

Is the communication intermittant only when the robot is running its motors, or if it is just on, you notice comm dropouts.

Posting your DS logs might help.

Definetly, get the short to frame fixed, because you could potentially be providing 12 volts to other things inadvertly mounted to the frame.

Note, you don't need to worry about resistance or voltage as much as simple continuity. If you have a digital multimeter with continuity mode on it, you can check to see if there is any continuity between the + or negative side of the PD board, and the frame. And you can do all of this without the bot being powered, so you don't need to worry about frying stuff if there are shorts.

You can also do the same thing with the motors you suspect are shorted (checking for continuity between either motor terminal and the motor housing).

Any continuity is an issue and needs to be rectified.
