Internet stops working after seconds

Hey!

My wired connection stops working a few seconds after reboot (wireless wasn't functioning to begin with): the Gnome network manager shows that it tries to connect but it fails and keeps on trying. One way to get it to work for a few seconds is to unplug the wired connection, though it will fail a few seconds after. Seems like something is overwriting, or something.

It is a fresh arch install. The thing which I did last time I booted was 'sudo systemctl enable NetworkManager.service', hoping to get my WiFi up and running. The WiFi can spot networks, but can't connect with them.

I tried rebooting, stop NetworkManager, but nothing works. The wiki https://wiki.archlinux.org/index.php/Ne … figuration didn't help. Ethernet module is loaded using kernel driver e1000e, the network controller uses iwlwifi.

Do you guys know what might cause this, it did work all day whilst configuring the system (and rebooting a few times).
Thank you very much,

Re: Internet stops working after seconds

I've a issue on NM like yours. My ethernet driver is alx. It is a newer driver. It sometimes causes problems when connecting with WiFi on. When this occurs I disable NM's WiFi option and power off my WiFi with button on my laptop and lastly reload my ethernet module. It works.

I tried your solution:
(turned off WiFi in NM, disabled it: sudo modprobe -r e1000e, sudo modprobe e1000e)
No luck, unfortunately. The wired connection still fails after a few seconds. Have a feeling that network manager overwrites something... no clue what or how i can disable it.

I assume that two services are interfering: I think I need Network Manager (the GUI and the easy WiFi set up), would anyone know what service would interfere with NM? dhcpcd.service? Sorry for the newbie questions: worked with ubuntu so far. Love arch so far, but it requires more in depth knowledge.
