Can't communicate with cRIO or d-link on power on

[DiscoStarSlayer]

Hello,

Our team has been having this problem the entire season and now we're realizing it's going to be a problem come competition time.

When the robot boots up the WIFI comes on, and we can connect but we are having a strange problem. If we ping the router at 10.22.0.1 and the cRIO at 10.22.0.2 we get no response. If we pull the ethernet cable out of the cRIO the router responds to pings, and if we plug the cable back in we get coms with the cRIO and it stays connected till we cut the power again.

This is fairly consistent, maybe about 5% of the time this problem doesn't happen.

Things we have tried:

Set laptop to static IP 10.22.0.5 + 0.6 + 0.9 with subnets 255.0.0.0 + 255.255.255.0
Reconfigured router using bridge tool and manually
updated firmware on router
Re-flashed crio, tried different team numbers like 10.22.1.2
used a different router, tried a different cRIO

info:
Java
Windows 7
Old cRIO's

I've been debugging this thing for the entire day and I can't figure it out. Any help would be great.
