blacklisted the r8169 ?
You can disable it, but tere is always a chance some app start it on demand like some panel app for internet connection, you may need to remove the app from panel or disable it to autostart…
sudo systemctl disable NetworkManager.service
or you can try
sudo systemctl disable --now NetworkManager.service
You could always mask the network manager then any program won’t be able to start it. If you need it back you can unmask it.
Interesting, this is new to me, how to mask a service?
man systemctl
Edit: If it is disabled only it can be started by another service(package) but if masked it cannot.
systemctl mask
unmask is unmask ![]()
That’s ok, since I installed r8168 then stop this below, it starts correctly and works fine :
systemctl stop NetworkManager.service
systemctl stop NetworkManager-dispatcher.service
systemctl stop NetworkManager-wait-online.service
Then start the dhcpcd :
systemctl start dhcpcd.service
systemctl enable dhcpcd
reading this section:
https://wiki.archlinux.org/index.php/NetworkManager#DHCP_client
is making me think of simple uninstall dhcpcd will solve this issue, as networkmanager do not need it
That’s an interesting idea!
I just uninstalled dhcpcd on KDE Plasma. It complained about being required for netctl but i uninstalled it anyway. Internet is working both on wifi and network.
just build an ISO without dhcpcd and it works without lagging and working network and installs just fine…
My internet is slow … ![]()

sure very slow

I can crank it up to 1500. But costs $$$ and i don’t have a server need. ![]()
NetworkManager tries to use dhclient by default but falls back to dhcpcd if dhclient is not installed.

And why my NM Applet doesn’t want to stop easily :
NetworkManager doesn’t find keyring secrets without nm-applet…

is also installed… there is simple no need for dhcpcd on a Desktop system running networkmanager… it is nice as a fallback on to enable internet connection but should work with dhclient too, it was default installed on archiso and used to enable connection… from CLI but as we do this from live session with networkmanager we do not need this…
You are in an area where you can get fast Internet too! I see Gigabyte speed. The fastest i can get here.

Decent over here. I could get a gigabit connection, but there is a price to pay. ![]()
