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.
