Incompatibility with Samsung Galaxy Tab S7 - Very slow Wifi performance
Hi team,
My internet connection is 1Gpbs and i use a Deco X20 has my main router, replacing the operator's one.
The Deco itself does the speedtest and it gives between 800-900Mpbs.
My devices (that are all non-WiFi6) normally have a speed around 400Mbps (iOS, Android, Windows).
I just bought a new Samsung Galaxy Tab S7 with WiFi6. To my surprise, the WiFi performance is very bad with the X20, not going above 60Mbps. I tried, formatting it, re-adding the WiFi network, disable QoS on the X20, always with the same result, 60Mbps. I can't enable/disable uPNP because it's not available on the firmware (by the way the X20 is much worse than the M5).
I tested the Tab on the operator's router and the speeds reach 400Mbps (It's not WiFi6), so this means there is something wrong with the Deco X20 -> Tab S7 connection.
The Tab S7 is the SM-T870 and has Android 11.
Can you please help?
