problem with mico controler

Hey anybody i need some help i have tried to hook up the vexnet wirelessly and it is not working i have used the new firmware and followed the insturction any thing that i might be missing?

I would suggest upgrading the master code to version 8.
Then attach the modules to the robot and the transmitter.
Power everything up and see it the pair correctly. If that
doesn’t work please call vexlabs so they can make sure everything
is 100%.

Read the instructions carefully,

Plug in the 9V battery
Check for the correct pair of TX and RX, the VexNET LED should turn green.
Sequence is important, don’t start the robot in Driver mode if you have autonomous

What programming IDE (robotC, easyC or mplab) are you using ?
