WiFi troubles


We are getting down to the wire with a competition this weekend. Our robot works fine with the ethernet cable connecting the Cortex “brain” to the joystick but will not work with WiFi

I have tried
switching out the batteries
different combinations of WiFi keys
re-loading the software
re-syncing the joystick to the brain
checked to see if the WiFi keys work on another robot and they are fine.
verified that the firmware was current

I always turn of the devices before unplugging.
I also unplug the brain before the joystick or laptop.
It has shown all good then the brain light on the robot turns red after a few seconds.

Any help would be greatly appreciated.

Hello BingBang,

I hope all is well.
This is strange. In order to provide you with an efficient response, please confirm if you have the VEXnet Keys 1.0 or 2.0?
I await your confirmation.

Also just to clarify: if you have the Cortex you need to tether it to the Joystick using a USB A-to-A cable, not an ethernet cable.
