Issues with WiFi Speed on manjaro-kde (Realtek 8821CE & TP-Link TL-WN822N)

[mrtrue]

Hello,

I recently installed manjaro-kde-23.0.2-230919-linux65.iso and am encountering issues with my WiFi speed and frequency. Specifically, I have the Realtek 8821CE card and also tested with a TP-Link TL-WN822N WiFi dongle. The speed and frequency performance on both devices isn’t as expected, especially when compared to their performance on Windows.

When I connect using an Ethernet cable, I achieve speeds of around 2 MB/s. However, with WiFi—even when I am directly in front of the router—the speed drops to approximately 1 MB/s.

Can anyone provide guidance or solutions to address this issue? I appreciate any insights or suggestions.

Thank you.

[HowTo] Find system information

Difficulty: ★☆☆☆☆ Rather than providing the commercial reference of a computer or piece of hardware, it is usually better to directly ask the system to describe itself. On top of saving time to everyone, this also often provides more details, including something specific to the running system. Below is a (not exhaustive) list of commands for retrieving system information. If you don’t know how to use those commands, or how to provide them to support, see: [HowTo] Use the terminal / TTY …

If dual booting windows: disable fast boot.
Searching with your favorite search engine for your network card & Linux & performance would be a good start.
