I recently purchased the Deco X90 twin pack and I am experiencing unusually slow Wifi speeds on the main and satellite X90 nodes. I'm using Ting Fiber internet, and have confirmed 750~950Mb/s connected directly to the ONT, or to the 1Gb/s port on main X90 node.
Even when using a Dell 7490 with an AX200 WiFi6 card wih Windows 10 x64, speed tests from any vendor cap at 420Mb/s down, and 80Mb/s up. I confirmed from Windows I am connected at 5Ghz on channel 40, 1361/613 (Mbps) R/T Link speed. which of the two nodes I connect to does not matter, nor does how close I get.
I get similar if identical speeds with 802.11AC devices including two other laptops and a Google Pixel 3XL. I could understand AC speeds being slower, but not this slow.
The X90 units are using the Wifi Backhaul to connect to each other. I got similar speeds when only setting up the first node, too. All default settings as well.
Is this working as expected? Am I missing something? Let me know what other information I could provide. I really like the range and setup of these, I just want to get the speeds I should.
