Exclamation cRIO random connection failure
Our team uses a cRIO from last year, which should be the same as they have this year. Our software and firmwares are all updated to the latest version. Today, we flashed the cRIO because our laptops were not connecting to it last night, and it connected once and deployed code just fine. But we turned the robot off and when we deployed code the second time, it no longer connects. Same thing happened last night: works some of the time after we power cycle everything but mostly refuses to connect. How would we fix this?

Our configurations:
Laptop IP: 10.30.70.6
Wireless Router IP: 10.30.70.4 (gateway)
Robot Wifi IP: 10.30.70.1
cRIO IP: 10.30.70.2

Setup:
Laptop-(eth)->Router-(wifi)->Robot Wifi-->cRIO

Testing results:
ping 10.30.70.6: pinging localhost works
ping 10.30.70.4: connects to router fine
ping 10.30.70.1 or 2: request timed out

Driver Station Output: "No Robot Communication"
