CAB1L problem

I would turn off the trainmaster base and the Cab2 so that only the Legacy base and Cab1L are on.

Secondly, use channel 9 on the legacy base. There are too many other devices in the lower channel range of Wi-Fi. It could be some strange interference issue.

Other than that, it sounds like you are doing the process correctly. Hold set, press the number of the channel, wait for the beep(s) It's a hold set, press and release the channel number. Don't release set until the beep(s)

What rev/version is on your Legacy base?  The Cab1L will only communicate with bases that have  V1.3 or higher.

I've used the CAB1-L here and at the club.  We have three or four people with the CAB1-L, they all talk to the Legacy base just fine.  FWIW, we do use Channel 9, seems to work better with WiFi around.

Thanks to all who replied. It seems that Ron "hit the nail on the head".  Lionel had sent the up-grade modules to me a long time ago, but I never knew exactly what I had.  I looked again and found that they were to up-grade to V1.3.  I took me a few minutes to find what to do in order to up-grade and another few minutes to actually up-grade.  But, when finished, my CAB1L started talking to the base just fine.
