Model: Deco M9 Plus  
Hardware Version: V2
Firmware Version: Deco M9 Plus(US)_V2_1.5.5_210519

Since last update my download speed reduced a lot. I have 125 mbts and now with the Deco M9 Plus(US)_V2_1.5.5_210519 update it goes down to 2.

 

Will try downgrading my deco . updating soon

@TP-Link so it wasn't a problem with the deco, it was with the modem. I only changed the Ethernet port from 1 to 2 in the modem and that's it. Problem solved. Thx

After the firmware update, please reboot both Deco M9 Plus nodes by powering them off then on to confirm if the speed will be back to normal.

 

If it is not, please follow the guide here to check the settings on the network, especially the QoS settings:

@TP-Link Same here. Reverted back to 1.5.3. 

 

 Stability and signal source with 1.5.5 very poor...

@Seb80 Hi!

 

Are you using the firmaware 1.5.3(EU) on the US version?

 

It's working well? safe to use?
