Changed out X60's to X90's but performance did not improve
I had a network of 6 Deco X60's. My Fiber connection is 1Gb/s symmetrical. I was not happy with the performance and reach of the X60's, so I decided to replace the Main Deco (connected to the router) to a X90 and another X60 in a room with bad performance with an X90 as well.
This was an expensive upgrade. To my negative surprise, the performance has not or hardly improved improved; in the room where I had my worst performance I'm only getting 180Mbs / 50mbs. Even in my home office, where I have a wired connection from my main Dexc X90 to the X60 in my office I'm just about getting 500/500.
If I stand almost next to my new Main X90, I'm getting 350/333 mbs.
I have some other issues as well after my upgrade; a number of devices, including all iPhones, now show up as "unknown" in my Deco App. Further, previoulsy I could test the connection speed from the main Deco into the internet (under "more" in the App). That is now also gone.
In short, I've spent 420 Euros but seem to be worse off.... Any suggestions? (I've also tried to get in touch with TP-Link Customer service on chat but that seems to be impossible.
