Speed test attached  @Js4utra 

  @Js4utra welcome to the club. I've had issues with every single firmware update I've done to these routers, to the point that they are about to be put out to pasture and replaced with something more reliable. Every time I do an update it completely kills my upload and download speeds for my whole network. If I run the Speedtest on the Deco app it shows the correct speeds up and down for my 2.5Gbps internet I pay for. However anything inside my network running a speed test shows insanely high latency and maybe 1/5 of the speed it should have. Sometimes a simple reboot or reboot of the firmware through the web page fixes it, or in down cases like today I've been screwing it for 2 hours and it's still broken. No one at TP-Link seems to know why it does this, which is why I'm on the verge of moving on to actually reliable equipment.
