Model: Deco M4  
Hardware Version: V2
Firmware Version: 1.5.8 Build 20230619

I was using Archer AX20 as wifi router that is able to have 300 Mbps.

Recently I change to Deco M4 with the same environment and cable but found out the speed is always less than 100 Mbps. I connect to laptop with ethernet cable has the same result.

Why is it? As I understand M4 shouldn't have this limitation

 

QoS is disabled

 

Attached is the router setting (sorry not English, didn't find where to change language)

  Turns out it is ISP issue. Can close this one, thanks.

Check QoS settings! There's a maximum bandwidth setting there, and it caps speeds to something below it per device. I think mine was set to something like 75M by default, and I didn't notice it on my 4G connection, but when I switched to a 250/250M fiber I did and was just about to contact my ISP, but then I searched and found said setting. I set the value to 250M and that fixed it!
