bridge/cRio communications sporadic

[nathanww]

I thought I'd seek input here on this rather intriguing problem:

When programming a prototypes system today, I discovered an issue with the wireless connection. What would happen was that when the electronics board was powered down and restarted, the wireless connection would only come back up about 50% of the time. On further investigation, this proved to be due to a malfunction in the link between the bridge and the cRio--ICMP pings sent to the cRio when the communication was down would just never get there, even though we could successfully ping the bridge.Changing out the cable did not affect the problem, and the robot runs fine tethered, which suggests to me that the problem lies with the bridge itself. After killing and reinstating power several times, the problem is resolved until the board is powered down again, after which it may or may not work.

Has anyone else had this issue or know of any solutions/workarounds? Our router and bridge settings are the same as we've been using to control our 2009 robot, and all our software is up-to-date.
