Under Consideration WiFi - Default 20Mhz channel on 2.4Ghz Band
1. Issue: IoT devices Tuya, Espressif, Raspberry etc facing continuous WiFi disconnection due to background noise in 2.4ghz band. By default Deco use 40Mhz width for communication currently makes entire network unstable (connection drop every 1-3 hours), even devices are only max 3-4 meter apart. Also smartphone sometimes switch to 2.4Ghz for some reason link are over 150Mpbs or 200Mbps but real speed are 4-11Mbps.
2. But when same IoT devices connect to 20Mhz width 2.4ghz (wr740n) even Deco network running in background frequent network gone like it's never exist. Ex - Devices Connected for over 4month seamlessly even a single connection drop and over 17meter apart, smartphone link are 72Mbps and [real 58Mbps].
3. Conclusion: People are requesting for manual channel selection in Deco model which not going to fix this issue, Also sometimes Deco switch to 20Mhz rarely which create same situation like wr740n. The issue is not channel it's the channel width.

I believe that leaving 1-star reviews under TP-Link Decos' Amazon products pages will have a better effect than this forum.

@Aura9x2l We need this fixed asap! It seems clear that the users are having problems and need to be able to set up the 20 MHz channel on a 2.4 GHz band. I passed the issues with the network dropping. Now my Tuya and Expressif devices don't even connect! My iAqualink (pool), Generac generator, Sense, WaterGuru, Bond, Resideo, etc, are worthless without an internet connection.
Please implement this solution in your next firmware update.
