Set bandwidth to 20 MHz selection for 2.4 GHz in Deco mesh
Hi,
I'm trying to force 20 MHz bandwidth on 2.4 GHz, but the option is not available in my Deco mesh setup.
My network setup is:
- 2 x Deco X95
- 3 x Deco X55
- 2 x Deco X50-Outdoor
All nodes are using Ethernet backhaul and the system is in bridge mode. The main Deco is the X95, since it is the most powerful node.
All firmware versions are the latest available as of 4/12/2026:
- Deco X95: 1.2.5 Build 20240903
- Deco X55: 1.8.0 Build 25102213
- Deco X50-Outdoor: 1.3.1 Build 20251030
It looks like the X55 and X50-Outdoor firmware branches support bandwidth selection, but the X95 does not expose this option in my mesh.
I want this because I have seen 20 MHz make a huge difference for IoT stability. My Creality K2 printer had repeated Wi-Fi issues on a separate BE230 router, but once I set that network to 20 MHz only, it became rock solid. I'd like to do the same here so I can keep broad mesh coverage for my IoT devices while improving compatibility.
My questions are:
- Is there an X95 beta firmware that enables 2.4 GHz bandwidth selection?
- If I switch the main Deco to X55, will I be able to select bandwidth for the whole mesh, including the X95 nodes?
