@mocelet Yes, you can disble band, see my screenshot above. It runs ok. For me is a bigger problem the channel selection issue.

@AshokSaini In the same place as always, on the right side, you can see 2'4 or select 5:

@adios Ok, thanks, that's better! I thought they had unified network bands for the Smart Connect feature. That's a good addition by the way.

@AshokSaini yes, after update im losing signal C6 - Archer T4U wifi card on 5ghz , want back to old firmware but can't

@adios 2.4Ghz is now totally unstable and unavailable. After a while cannot be reached and this has totally disrupted my Alexz network. And it is impossible to go back to a previous version of the FW. I am furious. Sent a message about to support and as usual no reply

@Johnblack have TP-Link support replied to your issue?

@evanslee Yes, by email from TPLInk Spain (I sent the online form too). They are going to "investigate" it.

Going to install right now.

THe problem is more complex. According to TP-link only one One-mesh device (in my case RE300) can be connected to the router. I have two of them and both are connected to the router as One-Mesh. My Router is Archer c6 FW version 1.3.3 Build 20200422 rel.80280(4555).  DECO E4 for mesh networks: only one network can be defined with them: no frequency selectable. And with Alexa? If DECO network should be used all ALexa devices must be reconfigured!! ANd there is much more and I suspect that the local TP-link is never come across these problems.... I feel very frustrated!
