Very bad news for such a big company and brand.

@SpirosX 

Yes, since the Deco app itself confirms that the default channel is causing interference

I can see that i have other wifi networks on the same channel but with lower power/signal. 

Not having the option to change the wifi channel at least on 2.4ghz band is a very bad thing for such a model.

We really do NEED this as an option.

This isn't a want.

My Deco's choose channel 6 even though every time we run the microwave it kills all 3 units signal.

It can't be that hard to put an override in the firmware so we can at least pick a channel that won't get walked all over by somethign else periodically.

I can suggest workaround specific for your situation, and if it works - why not to use it for now?

Deco mesh can be forced to rescan WiFi environment and select channel in following cases: when running Network Optimization in Deco app if that option is available, and when rebooting all Deco units.

You'll see Network Optimization under More in Deco app if your app has it.

You'll have "Reboot All" if you touch Globe on the main deco screen and then touch tree dots symbol at the top right corner.

The workaround: start empty microwave at its longest duration, 10-15 minutes is possible. While microwave is running, through Deco app do "Network Optimization" or "Reboot All." During that activity, Deco will scan environment and if it decides channel 6 has too much interference it'll choose different channel.

As an example, my Deco mesh currently runs WiFi 2.4GHz on channel 8. I also used to see it pick channel 4.

@Alexandre. 

While I do appreciate the "workaround",  this has been an issue brought  to TP-Link, over 2 years ago, and it's been requested multiple times as well.

What happens when my power flashes and the Deco's reboot without the microwave going, we're back to square one.

Please, please, please, suggest this to the dev team and get it implemented so we can save our channel.  I trust my own network scanning and manual setup over an "auto" config anyday.
