@Dave_BugOne Thanks for your message. I'm still hoping they can do the update for M9+. For now, I"ll have to put up with the inconvenience of the source signal randomly transferring at its own.

I am not receiving any response in my queries in this thread. Are the TP-LINK Engineers currently working to update M9+ firmware update. Unfair to provide only update to only M5 devices. Frustrated...

Any news for firmware upgrade 1.6 of M5 coming to M9+ users. It seems only M5 users are given priority for over a year now. We M9+ users have not been able control which mesh & device connects to...

TPLINK, Please have the firmware update (similar to M5) for M9+ available on DECO App. Why is it taking so long?

Good to know this exists. Hoping for the update to come to M9+.

@BrunoNascimento thank you for the information. Hopefully it comes soon to M9 plus users.
