If the Deco x55 system finds 2.4ghz channel 1, 6 or 11 not in use by any neigboring wifi system, the Deco system will select one of these non-overlapping optimal channels.  HOWVER, if ANY neighboring system is using channels 1, 6 or 11, the Deco system will select an wifi channel that is not one of the non-overlapping channels, i.e. not 1, 6 or 11.  This means that nearly ALWAYS, the Deco system relinquishes the best 2.4ghz channels to neighbors.  

This is not acceptable.

There needs to be a way to select the 2.4ghz wifi channel to use in the Deco app.  Let the neighbors' system jump to a non-optimal 2.4ghz channel.  I cannot understand why Deco developers will not provide Deco customers the means to manullay select the 2.4ghz channel to use.  Perhaps an advanced setting, with the normal non-advanced default to be auto select.

Whenever I am lucky enough to boot up my deco x55 system and there is a window of uncontested availability on channels 1, 6 or 11, the Deco x55 system will select one of those channels.  My system performs very well until, perhaps days or weeks later when I need to reboot the system or  there is a power glitch and the Decos are ofline for a moment, without fail neighboring wifi systems will grab whatever optimal channel the decos had been using.  Then sadly, as the Deco system completes its reboot, the Decos will revert to using one of the overlapping 2.4ghz wifi channels, i.e. NOT channels 1, 6 or 11 since the neighbors' systems are wisely now using them.

I say let somebody else's wifi system use a non-optimal channel.  I prefer to use channels 1, 6 or 11 -- my wifi system performance is MUCH better on these channels and if/when I am lucky enough to have my Decos select one of these channels, invariably the neighboring wifi systems switch to other channels leaving me with optimal performance.

I have 6 decos and neighbors on all sides so many of my Decos see neigboring wifi systems of various channels on all sides, but those systems are at the fringe of my system's rang.  Therefore, within my property between my 2.4ghz devices, performance is better on channels 1,6 or 11 regardless of what the neighboring systems are doing

Mesh system providers other than TP-Link provide this option for their customers, trusting that their customers have the ability and intelligence to be able to use such an option  effectively. 

Please, please TP-Link, listen to your customers and give us the option for manually selecting the 2.4ghz wifi channel the Deco X55 will use.

Surely TP-Link has the same faith in TP-Link customers' abilities that other manufactures have in their own customers.

Thank you.
