Hi everyone,

I have 3pack Deco E4 (US) Ver. 4.0, and I'm running into an issue with the 5 GHz WiFi network. Some devices simply cannot see the 5 GHz SSID at all.

After digging deeper, I found that the problem is related to the channel width, which is currently set to 80 MHz. For compatibility reasons, I need to manually change it to 20 MHz, since several of my devices don’t detect 5 GHz networks when the channel width is too wide.

My entire infrastructure uses Ethernet Backhaul in router mode.

I already tried modifying the channel width through both the Deco app and the web interface, but neither option provides a way to change it manually.

Does anyone know if it's possible to adjust the 5 GHz channel width on this model, or if there's any firmware update/workaround that allows manual configuration?

Thanks in advance!
