My M9 plus main Deco gets so hot underneath that I cannot touch it anymore.

Hi, welcome to the community.
May I know how long you have had the Deco M9 Plus?
Deco M9 Plus is a flat circular shape, so its CPU module is quite close to the outer shell. And the surface temperature will be slightly higher.
For more details, please refer to Is it normal that my Deco feels warm?
Thank you very much.
Best regards.

I just started to use them.
Since the heat is at the bottom , a wooden surface will get marks after a while.

If the CPU gets that hot, either something is wrong or the CPU is clearly underpowered.
The heat also causes drop-outs, which makes it even worse.

Hi, sorry for the delay.
Can I have the current firmware version of your Deco M9 Plus?
The latest firmware should be 1.8.1. If you're not on this version, please manually update the firmware via web UI:
Deco M9 Plus_1.8.1 with Wi-Fi Access Control and ECO Mode Ready for Test
If it was on the 1.8.1 already, as Deco M9 plus was EOL for a while, and if you just bought this model, it would be better to replace it with another model, such as Deco X50:
