Need help pairing 1st gen controllers with brain after tethering

several of my students are having trouble with the wireless transition after tethering. It never finishes after removing the tether. We have tried : updating firmware, motors, brains, re-wiring motors and recalibrating the controller, setting to defaults, clearing all programs. Any ideas would be appreciated.

Are the radio modules pushed in all the way? Do the radios pull out easily?

You have to start with both things off, then plug in the tether and turn them back on the unplug the tether, make sure there are radios in both devices

Make sure you are using a hi quality cord to link them and that you don’t have other programs open that are using the ports (do not have VexOS open at the same time as VexCode)
