Wireless Packet Drop during competition

[boz336]

Wondering what could cause wireless packet drops during competition.
On a couple occasions we lost comms for about 30 seconds.
We talked to the FRC technical volunteers who did their best to help us diagnose, but we're not entirely sure and we have another competition next week. For reference we're using the new Robo Rio and a brand new DLink.

Their suggestions were:
1) Our mecanum drive system is drawing down the battery voltage to below the brown-out level. But this one was de-bunked after we went into the log file and looked at the voltage levels and confirmed we were above brown out.

2) Some "other" event caused the issue. Two theories were A) Wiring connection came loose (ethernet, or power) and B) our Dlink was not oriented correctly.

We re-secured our cabling, but had already duct taped all connections in place and they don't appear to move when the robot is moving around.
Our D-link isn't near any motors or other sources of EMI. Can the orientation of the D-Link make a huge difference? Vertical vs. Horizontal vs some random angle?

Thanks for suggestions!
