Hey Juan,
I'd expect to be some ripple if you are drawing near the max continuous current (1.5A VRM User's Guide).
I didn't really understand this...

We had an issue with one of the VRMs on our test robot last week where the radio would intermittently drop the driver station, but maintain communication with our debug PC. We're using LabVIEW on our robots this year.

...so I grabbed my mecanum kit bot which uses a DAP1522(VRM1 - 20A fused) and M1011 Camera (powered from VRM2 - WAGO20A snapaction) and drove it around for a while. Ran a full battery down to the point where DS was in constant "Voltage Brownout" meanwhile watching the Axis Camera on the laptop running the DS. I didn't seem to lose camera or the router the entire time. Which seems like a good test of the power supply of the router and camera (each a VRM). Also ping times to the RIO seemed ok so I'm not sure this if the VRM has anything to due with your disconnects.
Plus Beta teams spent a lot of time beating up that aspect of the robot.
Can you explain the original problem a bit more?
