Issues with WiFi Speed on Endeavouros-Cassini-Nova (Realtek 8821CE & TP-Link TL-WN822N)

Hello,

I recently installed Endeavouros_Cassini_Nova-03-2023_R3.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.

welcome here :enos:

Could be bad luck with both devices…

Realtek are known to be problematic… and the TP link is mostlikely also a Realtek wifi chipset ?
rtl8192 ?

inxi -Naz could tell more with both devices plugged in…

Ethernet is duplex - full transmit and receive at the same time.
WIFI is half duplex. One transmit the other receive. Then they switch … at very high speed … but your numbers look normal to me. WIFI is radio communications :slight_smile:

edit:
I made a small search for you:

It correspond roughly to what I have learned at Teccart in Montreal.

You will not get the same speed on WiFi as you get with Ethernet. The only way to get faster WiFi is to have hardware that is capable of being faster. That includes the WiFi standard that the router has and also your WiFi card and or WiFi dongle.

Yes, sadly, both of them have Realtek chipsets. As I mentioned, in Windows, the WiFi speed is the same as the Ethernet cable, and I don’t have any problems with WiFi speed at all.

would help to see device specifications…
Could be you need to install a better driver to have them working nicely…

rtl8821ce has an AUR git driver build:
https://aur.archlinux.org/packages/rtl8821ce-dkms-git

if second one is a rtl8192 there are some builds too:
