Any updates on this for the PX50 also? I have some devices that couldn't see the netword when the PX50 was on channel 12 but it appeared once the channel was dropped to 6 but it's luck of the draw with the optimize feature in the app.

Just to let support know, I decided to return my AXE5400 mesh system today due to the lack of this very basic feature. The system was far worse performing than my cheap 5 year old Orbi and I can't wait for firmware updates that "may" implement the feature.

I just bought XE75 recently to replace my existin Unifi router and Access Point with the hope to improve the wifi speed. Unfortunately, I was very disappointed. I spent A$600 hoping to improve my wifi network but ended up the worse than ever.

The same problem that everyone here is facing, I cannot assign specific wifi channels on 2.4Ghz and 5Ghz as I could on my unifi access point.

The XE75 wifi is very unstable, I keep getting disconnected while on Teams meetings, when connected to XE75 wifi but not on Unifi.

The reason I need to manually select the channel is because I have a Samsung phone and some models have trouble with lower 5GHz channels.

Since my router picked 36 and my phone doesn't see it, I am screwed. :-(

I'm guessing adding to this topic is like beating a dead horse, but I'll throw in a reply anyway. 
 

My neighbors are using channels 6 and 11. For some reason, my 3 node M5 network settled on channel 8 and said things were 'perfect' no matter how

many times I optimized the network. Things were far from perfect. 
 

My 'fix' which I only recently thought of has been this:

Fire up two decommissioned access points (old D-Link and a Netgear, key thing is being able to set a channel / imagine that). Put one on channel 11, another on channel 6. Set both AP's right next to the main deco. Leave them on for a minute, run network optimization and suddenly there is interference. Network optimization chooses channel 2, and my 2.4 GHz network is fine again. Until a reboot happens and it goes to a conflicting channel. 
 

Why Deco won't pick channel 1 is beyond me. Channel 2 has a slight overlap with 6, but not terrible. 
 

Should I have to do this? In 2023, no. Does it work? Mostly. It is an inconvenience, and an unnecessary inconvenience. 
 

Strongly considering a rip and replace due to this and a few other lingering issues. I've dealt with this and other issues for 3 years now. Hard to think something so seemingly simple can't be easily accommodated. 

  @David-TP I dont understant, on webportal is prepared to change channel...

When we refresh the page the channel is a selection box

Please allow us to change the channel and the bandwidth on 2.4Ghz.
