Incompatibility with Samsung Galaxy Tab S7 - Very slow Wifi performance
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
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?
I'm connected in the 5Ghz frequency. The connection on the Tab show up 1.2Gbps. But the test speed does not pass 60Mbps. I tested in the Deco Lab App, same result. But again, if you test the internet speed, on the Deco App...900Mbps. I have 3 Decos X20's, and it's the same in all. I also restarted all of them.
