Cannot setup PTMP with a 3 C5Xs

I have three C5x units when i setup one as PTMP AP the clients cannot see it.
I need the two C5x PTP station units to talk to the PTMP unit.

The C5x only works as a PTMP client, not as the access point. I’ll agree that the documentation needs improved. The Spec Sheet for the C5x simply states that it works PTP & PTMP through most of it. When you get to the Technical Specifications, under Performance, it does state “Modes: PTP Backhaul; PTMP Client”. This is on page 2 of the Spec Sheet for the C5x.

For the access point, you may want to try one of the A5 series of radios.

Thank you for your quick response Wayne. I am now clear.
