yeah, buyll***** isnt, Samsung should be shame, 


anyway if you switch to 5G wifif instead of 2.4hz its working proper unfortunately not everywhere is 5g


Hey guys, was testing my Wi-Fi speeds today on my S9, and it seemed like I couldn't get more than ~40Mbps regardless of 2.4GHz or 5GHz, which didn't seem right as my other devices consistently achieve 100Mbps.


After experimenting, it turns out Ookla's Speedtest app is bugged. Other speed test apps correctly show my speeds, whereas Speedtest is maxing me out at 40Mbps. Seems to be the case on my iPhone as well. Just posting my experience, sorry if it didn't fix yours!

Hello, I had the same problem. I went to an internet provider and he changed my router's frequency from 2.4 to 5 G and the problem was solved. I hope this is a permanent solution.

Download from the play store. I use this and it sorts the slow wifi issue out on my S9 while it's active.

THIS IS IT! Removing mouse (Mi mouse) from connected Bluetooth devices solve the problem for me. Thank you!
