I have been using one called wifi analyzer open source, and it works nice.

Unfortunately since I watch the rio reset, I don't believe it's because the 2.4 Ghz is overcrowded. It's worth checking however.

It could be grounding or static issue. With the robot OFF measure resistance from the frame to the PDP ground (any ground will do, they are all connected). Then check the frame to a ground on the rio. I usually measure it to the metal shield on the USB port. You should ideally get open circuit, but anything under 1M should be investigated in my opinion.

The grounding/static issue is a good thought that I've neglected to check. All of our electronics are mounted to lexan, but it's worth checking. Maybe we have a stray wire somewhere that wasn't cleaned up/removed. It also reminds me that our lexan electronics board is awfully wobbly. I wonder what the rio can accept vibration load wise? Additionally, you're correct - we have 4 CIMs on PDP12-15.

Not a bad thought, but we've tried several different batteries. However, I don't know how closely I've checked the anderson connector that the battery connects into. We'll have to check that out tomorrow.
