@TP-Link I have the same problem with my Bose system. Before getting the Deco X68 router never had an interference issue. Since installing these my sub and surround speakers crackle and pop nonstop.  Were you able to fix your issue?

Sorry for the late response. I never received a direct answer. It would be a simple thing to add this to a beta firmware and test. The interference is 100% caused by my Deco router. I can repeat the problem by simply turning on the 5ghz band. As soon as I do that, I get interference in my speakers. Turn it off and it immediately goes away. 

I wish someone from TP-Link would contact me about adding this most basic of features back to the firmware so I could just change the channel.

 Seems like this type of functionality would be highly beneficial to the end users, especially on these more robust units (X60/68 and up).

I agree.  I even tried using the browser.  I would like to move my channel as well since optimization has no affect.

Isn't channel 10 a 2.4g channel?

A 5G channel should be in a range of 36 to 177.

  @TP-Link Why is it that we cannot utilize channels 149 through 165 on 5 GHz?
