Hotspot Wifi slow

Hello everyone,

I’m running a dual-boot manjaro(gnome) and Win10 machine. The machine is connected to the internet with a 100 Mbit/s copper-cable. Due to the fact, that I’ve no wifi in my room, I’m running a Wi-Fi- Hotspot on this machine. This hotspot is running on the 5Ghz-Network. When I run a speedtest with a device connected to my manjaro hotspot I get approximate 5 Mbit/s. When I then reboot my machine and start to “Windows 10” I get about 50 Mbit/s (2.4 Ghz). (The ping stays approximate the same with less then four ms.)
I want to speed up my manjaro hotspot-Wifi speed, since I rarely use Windows 10. (Less then 10% of my time, and only if I need it for work.)

What I’ve already tried are the following points(from Slow speed on Hotspot created from Ubuntu 16.04 with RTL8723BE Wireless Network Adapter - Ask Ubuntu)

  1. Play with the antennae number
  2. Play with the power saving modes
  3. I checked even the entropy level, which is over 3000
  4. I tried also changing to the 2.4 Ghz Band, but then the speed dropped to 0.5 Mbit/s

(Funny was, yesterday when the hotspot window problem was, I was playing around with these possible solutions and then I thought I broke something.

So I’m asking you, what you consider to be other options to speed up my wifi-hotspot? (If you need additional information, just say so, due to the fact, that I’m not sure, what may is still relevant.)

Thanks for your answers in advance.
PS: Even if I read my writing twice, I’m excusing myself for any mistakes.

Edit: As @TriMoon suggested I provide some further information about my system: (I’m sorry for not providing it immediately)

I’ve made my hotspot as suggested here: https://www.linuxuprising.com/2018/09/how-to-create-wi-fi-hotspot-in-ubuntu.html with option 2. And I’m using “WPA & WPA2 Personal” as security method.

It might help if you provided detailed info on how you setup your Wifi Hotspot in Manjaro with related configs.

Also, did you use the driver mentioned in that topic from the link in:

Anyhow, help others to help you better by providing enough info about your computer and it’s hardware.
Because with things like this it could be related to drivers and/or kernel etc. beside software configurations.

Thanks for your answer. I’ve not seen this driver. I will take a look at it, this evening and update you as soon as possible. (I’m currently working and can’t try out new drivers…)

So I’ve taken a look at the driver and during reading the “README.md” file I’ve found:

Note: If your kernel is 4.17 or newer, AND your card is not an RTL8723DE, then you should NOT be
using the external driver. The built-in one is the same.

This applies to me, since I’m running a 5.9.12 and RTL8821AE is not RTL8723DE, so unfortunately it does not apply to my case. So therefore no need to install the new driver.
