Model: Deco XE75  
Hardware Version: V1
Firmware Version: 1.1.8 Build 20221121 Rel. 36280

I have problems listening to a G NEST AUDIO in the kitchen when using Spotity(connect). The music/radio stops from time to time...
My Deco xe75 (used in AP mode) chooses channel 12 on 2.4ghz and curiously channel 11 is the strongest of the channels used by neighbours. But well, we already know that tplink has the intelligence to choose the channel...so there must be a reason for this.
What I find incredible is that it connects with 40mhz width. In 5ghz band I changed it to 80mhz (from 160 by default) and it improved the stability. Because in building blocks there are a lot of channels used and 160mhz seems to me to pick up too many channels. For this reason I bought the xe75 to use 160mhz in the 6ghz band.

My featured request is : Can you give us the option to set the 2,4ghz band to 20MHZ?
I live in a environment that there is no space in 2,4ghz to put 40mhz.


Thanks in advance.

Apple also recommends using 20MHz for the 2.4GHz band.

 

  • Set to 20MHz for the 2.4GHz band
  • Set to Auto or all widths for 5GHz and 6GHz bands

 

Channel width specifies how large of a “pipe” is available to transfer data. Wider channels are faster but more susceptible to interference and more likely to interfere with other devices.

 

  • 20MHz for the 2.4GHz band helps to avoid performance and reliability issues, especially near other Wi-Fi networks and 2.4GHz devices, including Bluetooth devices.
  • Auto or all channel widths for 5GHz and 6GHz bands ensures the best performance and compatibility with all devices. Wireless interference is less of a concern in these bands.

I hope TP-Link gives us the option to choose within the next firmware updates...

I agree. They should let us choose 20 MHz.

 

Increasing WiFi channel width more than 20 MHz when using 2.4 GHz is often not worth it because it can lead to increased interference with other devices using the same spectrum.

 

This is because 2.4 GHz is a shared spectrum that is also used by other devices such as Bluetooth, microwaves, and other WiFi networks.

 

When you increase the channel width, you are effectively increasing the amount of spectrum that your network is using, which can lead to more interference and a decrease in overall network performance.

 

Additionally, some devices may not support channel widths greater than 20 MHz, which can also limit the benefits of increasing the channel width.
