Slow wifi speed using mobile hotspot but not on home wifi

[Sle3ven]

Just installed linux mint on a second hard drive on my pc. Everything works great except, my internet speed when using my mobile hotspot.

 

My home network is a wireless 4g router and is almost useless most of the time due to many users(my family) and poor connection. To get around this problem ive used my phone as a hotspot since i get better speed.

Ive been using it for about 2 years and in windows there is no problem. I get easily  10 mb/s down and 3-5mb/s up with it.

However, in linux i get less then 0.5mb/s up and down. 

Updated the drivers for my network card and if im on my 4g wifi i can alteast hit 1-2mb/s and if no one is on it i get around 5-7mb/s.

 

Im new to linux so i dont know much about it therefor im turning to this community for help.

The speed got a little bit better but still not usable. +my house has alot of grey area for celluar connection so the only place where i get good connection with my phone is way out of usb reach.

So it seems like it might be a problem with your wifi adapter's driver... what model is it? You should be able to find out with

lspci

Have you tried installing bcmwl-kernel-source?

If not,

sudo apt install bcmwl-kernel-source
sudo modprobe -r b43 ssb wl brcmfmac brcmsmac bcma
sudo modprobe wl

Driver manager says that bcmwl-kernel-source is already installed and in use.

If i run 

sudo apt install bcmwl-kernel-source

i get; bcmwl-kernel-source is already the newest version (6.30.223.271+bdcom-0ubuntu5~18.04.1).

Then it's possible your adapter just isn't well supported by broadcom on Linux, unfortunately that can happen. If you can, try staying closer to your phone.

Actually now that I think about it there's one more thing you can try - check if your phone is broadcasting on the 5GHz band and if it is, switch to 2.4GHz.

Unfortunately it is using 2.4GHz so its not that.
