I can offer things to verify and check.
I assume you have applied LabVIEW Update 2, and imaged the cRIO with v7. If in doubt there are ways to verify the versions of each.

Verify your LabVIEW project is using the correct IP address for the cRIO target (10.18.83.2). The IP address is displayed in the LabVIEW Project Explorer window as: RT CompactRIO Target (10.18.83.02). If it is not correct you can fix it with a right click to get Properties.


Verify your communications:
I wasn't sure what you meant by the cRIO is connected to the router, since it shouldn't be physically connected to it, but only in contact via wireless.
Do the Driver Station and cRIO communicate and run properly with the default code?
i.e., does Enabling the Driver Station give you a solid status light on the cRIO's Digital Sidecar? And does Disabling the DS make the Digital Sidecar status light blink?
This should confirm that your comm wiring is correct, except for the PC and that should be plugged into the Driver Station ETH2 port.


Check your PC:
Verify the PC's IP address (10.18.83.6), Subnet mask(255.0.0.0), and Default gateway(10.18.83.4) are as they should be.
Disable any PC firewall.
Disable any wireless network card.
Test communications to the cRIO by:
-- Start -> Run
-- then type cmd and OK
-- then in the window that pops-up type: ping 10.18.83.2
If you get a message "Request timed out." then your PC truely cannot see the cRIO.
