Hello, Is there any update about this? Could you please advice if is there an open issue with the TPLink Developers to solve this?

Thanks

Sadly, useful features like this get dropped when a vendor decides to "dumb down" their product line.  Glad I caught this thread BEFORE buying the Deco mesh solution. I absolutely need multiple SSIDs ideally with separate VLANs and the ability to control SSIDs by 2.4/5Ghz. If TP-LINK (understandably) wants to keep an easy-to-use interface, then hide these settings behind an advanced mode.

And of course, I noticed that (like most companies), TP-LINK sadly does not read or participate in the community discussions.  #placebo

I have the same issues with HEOS wireless speakers. They have lots of playback issues if one pair of speakers is connected to the Deco M5 and one or multiple speakers are either on the 2.5 GHz or 5GHz network.

I can fix this temporarily by forcing the HEOS speakers to go to the 5GHz WiFi network by disabling the 2.4 GHz network in my Deco app. But this is a not very good solution since it constantly happens that one or a few of my HEOS speakers end up on the wrong network and sound is then interrupted.

I would like to have used the Guest network for connecting my IoT devices or my HEOS speakers, but the guest network is separated from my main network so I cannot use the Guest network to have this solution in place, it would require me to manually switch from standard WiFi to the Guest WiFi if I want to control my music what is also not a solution that I want to have in place.

Looks like I need to abandon the use of the TP-Link Deco M5 to solve my issues :(.

Update from 19.07.2022, yes the Deco M5 Firmware saved my Deco M5, I can now configure what WiFi band is used by any individual device. Very cool update indeed :):)

Yes cool thank you very much, I was so frustrated because my HEOS wireless speakers constantly connected to either the 2.4 and 5 GHz band and this ruins the sound totally, I desperately ordered the Xiaomi AX3000 Mesh system that allows for having two SSIDs set up for the separate bands.

I now read your suggestion and reconfigured my M5, it can stay. Since I do not have any WiFi 6 devices I will return the Xiaomi AX3000 unopened for a refund.

Thanks again for letting me know about this really cool feature that came with the 1.6.0 firmware for the Deco M5 :).
