Slowdowns and connection drops on Fedora 43 with a rtl8821ce wifi chip.

🍖

...what we need to is: 

     sudo nano /etc/NetworkManager/conf.d/20-connectivity.conf

Add the following to the file:

[connectivity]
.set.enabled=false

Then save by pressing CTRL+O, then Enter, and exit by pressing CTRL+X. Restart NetworkManager using

     sudo systemctl restart NetworkManager

and that should be it.

The good news is that the driver is in the kernel, the bad news is that it very aggressively checks for connections. There are alternative drivers for Arch and Ubuntu (like this one on GitHub), but why change it when the default drivers is good enough.

That same link has an important tidbit that we could use. How to disable the periodic scanning.

We are going to disable the Connectivity Check option in NetworkManager. This by editing the file in /var/lib/NetworkManager/NetworkManager-intern.conf and adding the following instructions at the end:

[connectivity]
.set.enabled=false

However, that's a system file and you will lose the configuration next time NetworkManager updates or restarts. 

 

Instead, what we need to is: 

     sudo nano /etc/NetworkManager/conf.d/20-connectivity.conf

Add the following to the file:

[connectivity]
.set.enabled=false

Then save by pressing CTRL+O, then Enter, and exit by pressing CTRL+X. Restart NetworkManager using

     sudo systemctl restart NetworkManager

and that should be it.
