Unnecessary "Connection failed" messages when on ethernet

Support Network
1

Hi, when i’m in the house, on Wi-Fi, I am not getting any issues. When I go out to my office and plug the laptop into ethernet, i’m connected just fine but occasionally (every few minutes) I am getting these messages.

The only reason I can think why, is that it’s telling me that it can’t connect to Wi-Fi. Am not 100% sure though as I don’t think it should be trying to connect to a Wi-Fi network when it’s got a solid ethernet connection.

does anyone know what log files might come in handy to troubleshoot, or have any idea how i can sort this out. would be appreciated.

Also, a bit of info about the system and the networking devices:

Hi there. Apologies if I’ve overlooked it but what desktop environment are you using? Xfce? Thanks, R

Hi @ruziel, thanks for replying. DE is Gnome :+1:

I would check and see if the hardware manager has a different driver available for your Ethernet

Information in post#1 shows RTL8111/8168/8411 Ethernet Controller is using r8169 driver

Wired connection keeps dropping - #6 by nikgnomic

Manjaro hardware detection tool can install kernel modules for r8168 driver and blacklist r8169 driver

sudo mhwd -i pci network-r8168

Or use Manjaro Settings Manager GUI:

manjaro-settings-manager -m msm_mhwd

enable option in bottom left corner - Show All Devices

Look in section Network controller > RTL8111/8168/8411 for network-r8168

Right click on network-r8168 and select Install

Manjaro Settings Manager should install r8168 driver for each kernel version on system and blacklist the r8169 driver
