Roborio Comm light is off

[hwu24110]

We've had the problem of the comm light being off since yesterday. Yesterday, the robot was working fine and completely operational. We were using the DAP-1522 radio since it was already configured and I just needed to get the robot complete. I decided to swap it out with the OM5P-AN radio to see if I could get it to work. I managed to get it configured, but the robot was no longer connecting. I noted the comm light was off so I experimented and swapped it out for the same DAP-1522 radio and found the comm light was still off and I still couldn't connect.

Today I reimaged the roborio and installed Java and got the robot functional again. I could connect to it via wifi with the DAP-1522 radio. I then swapped out a Talon SR with a Victor SP to test it and it still connected fine. I swapped the Victor SP with the old Talon SR and then the comm light was off and I couldn't connect. I didn't touch any of the wires except the wires leading from the motor controller to the PDP and the PWM. I tried reimaging and downloading java on the roborio, I momentarily got a red comm light, then it went off. I tried the same process again and then it wouldn't come on.

I've checked the firmware version for the roborio and found it to be 3.0.0f0. As of right now, I cannot connect to it via USB nor build code to it. I'm not with the robot right now, but I can check tomorrow.
