========================================
Hi, the shared connection via Wi-Fi is very unstable. I need to share the internet on my pc, and it's hell, there are continuous ups and downs, there is no stable connection. I have stable 4G + network coverage, but the shared connection is very bad. Hope they can fix it.

Here you have a photo. It is always like this, even sometimes it stops sending data ... it's horrible, because the connection stops continuously. It is not my pc's problem, because I have tried it with several computers, and the same thing happens in all of them.
I feel my bad English .. I am using Google translator.

This screenshot doesn't tell me much. It only shows me that you hade a maximum download speed of 11mbps and an average of 7.7mbps. I don't know if you're trying to download a single file from a website or downloading torrents. I don't know what kind of speed your phone can reach when it's not sharing its connection.
You need to give us a lot more information if you want our help

@Anders_ASUS I have stable 4g ​​+ coverage, when I share the connection with another PC, the data transfer is not stable, it suffers from ups and downs. My 4g + gives me a download speed of 10Mb but when I share the connection, if I download a large file, the speed is not constant and I will go up and down as you can see in the screenshot. What I mean is that the shared connection is not stable. My cellular network is stable, but when sharing the connection, it suffers ups and downs, and sometimes it even stops. I hope now you can understand me
