Network usually not working upon resume from sleep

When I put my computer into standby, upon waking it usually does not have an Internet connection, despite the Ethernet cord being plugged in and the network working just fine.

I try restarting networkd or resolved, but that doesn't help.

When I try to ping any address, I get:

ping: socket: Address family not supported by protocol
ping: 1.1.1.1:8080: Name or service not known

I always need to reboot to regain the connection.

This is my motherboard: https://rog.asus.com/motherboards/rog-s … ing-model/

Re: Network usually not working upon resume from sleep

Can you either

sudo ping 1.1.1.1
ping -4 1.1.1.1

Compare

ip a
loginctl session-status

before and after the S3

Re: Network usually not working upon resume from sleep

sudo ping 1.1.1.1
ping -4 1.1.1.1

Same result.

Compare

ip a
loginctl session-status

before and after the S3

The only difference I notice is mullvad-vpn being missing from `ip a` when the connection is down (makes sense) and all the other network-dependent software missing from `loginctl session-status` when the connection is down.

Judging by `ping -4` not working for me either, I don't think this applies

Re: Network usually not working upon resume from sleep

mullvad-vpn being missing

So you're relying on a VPN… you best post the actual outputs of either command to get us an idea how your network is setup to begin with - but the cause is likely that eg. networkmanager shuts down on the S3 and does not or fails to restart afterwards
=> Also inspect your system journal (sudo journalctl -b)

Re: Network usually not working upon resume from sleep

Thanks, that helped me narrow it down to the app I'm using: https://aur.archlinux.org/packages/mullvad-vpn

If I disable it from launching on startup, the problem doesn't occur.

I found the related issue:
