@David-TP  Hi David thank you for the reply.

I have not tested with an Ethernet connection speed as surprisingly I don't actually own a device I can hardwire and run a speed test on *waves fist at these modern laptops with no ethernet ports*

The mobile device I was using for the speed test was an iPhone 12 Pro Model number MGMX3B/A

When I check the wireless transfer speed (following the link suggested) the tx rate can go from 720Mbps to 916Mbps which I guess indicates the router is cable of higher transfer speeds.

QOS has always been disabled. I can achieve higher speed on other devices now that I've done a more thorough test, but I'm just puzzled that my main mobile device was getting a higher download and upload sat next to the router with the m5 deco compared to what it gets now with the x50.

Hi, Thank you very much for the feedback.

Have you tested the Ethernet connection speed from the main Deco X50?

 

Can I have the model numbers of the mobile devices that are used for the speedtest?

-Please also refer to this link to check the current wireless link speed on these devices- How to check the associated/link speed on a wireless client.

- And make sure the QOS has been disabled or set to 1000Mbps-download/upload.

Wait for your reply and best regards.
