You may also want to have another computer join the drink AP and see if it can still ping the cRIO, the AP, etc. Do you have lots of wifi APs nearby that may be causing issues?

My team is currently PID testing, so I can't post the log file atm, but from viewing them in the past, all you see are dropped packets when the communication goes down.
No crio cpu spikes, or anything like that.

The dlink stays constant, and we never lose actual wifi connectivity.

We have had a computer pinging it, and when we lose robot code, it will stop receiving a ping for about 1 or 2 pings, then it will receive one, lose one, as the communications go in and out


as for other wifi hotspots, we did a packet sniff, and changed our ap to the channel that was less populated (all the other wifi aps were on channel 11, we went to 1)
