Hello,

I'm experiencing an issue with my Deco BE25 v1.0 mesh network where the 2.4 GHz wireless settings are not being maintained after saving.

Setup:

• 3x Deco BE25 v1.0 (firmware 1.1.7 Build 20260114 Rel. 14971)
• 1x Deco BE22 v1.0 (firmware 1.1.1 Build 20251024 Rel. 6853)
• All units connected via wired backhaul
• Wired backhaul mode set to "Best Performance"
• MLO disabled

Issue: When I manually set the 2.4 GHz channel to 11 and bandwidth to 20 MHz, the router does not maintain these settings. Specifically:

• The channel automatically changes from 11 → 9 → 6 on its own, ignoring the manual selection
• The bandwidth reverts from 20 MHz back to Auto (40 MHz) automatically
• The Deco app shows the correct settings saved, but the actual broadcast channel keeps changing

Why this matters: I have many IoT devices (Tuya smart plugs, switches, and other 2.4 GHz only devices) that keep disconnecting frequently. Fixing the channel and bandwidth to 20 MHz is essential for IoT stability.

Expected behavior: Manual channel and bandwidth settings should be respected and maintained until changed by the user.

Please advise if there is a fix or if this will be addressed in a future firmware update.

Thank you.
