Help setting up wifi... [SOLVED]

Hej guys,

I have installed wpa_supplicant, netctl and wifi-menu.

With this combination, I have got wifi working on my other devices very easily and quickly. On my new laptop however, I keep getting vague error messages. The config files (below) are actually exactly the same on my other laptop which works fine.

One thing that I have noticed that is odd is that on my other laptop I do not need to sudo to edit the files in /etc/netctrl, but on my new laptop I need to use sudo. Some setup difference that I have missed somewhere? Maybe a permission problem? I don't remember changing anything on my other laptop (unfortunately I don't have it with me at this minute to check the setup). Also, it still doesn't work in su mode.

Error:

Re: Help setting up wifi... [SOLVED]

/etc/netctl/<mynetwork> should be owned by root.

Your systemctl and journalctl outputs are cut off. Use --no-pager or scroll right/left. Post the whole output.

https://wiki.archlinux.org/index.php/Netctl
Look at the troubleshooting section. Look at the warning for .include directives.

Oct 16 15:03:39 ArchDell network[1393]: The interface of network profile 'WorkWifi' is already up

Some other service (possibly dhcpcd?) brought the interface up, please post the output of

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Re: Help setting up wifi... [SOLVED]

Thanks for the replies guys.

Taking a tip from the second post there, I disabled dhcpcd (systemctl disable dhcpcd), rebooted, and it now works fine.

I was under the impression I should have dhcpcd enabled though ... in order to automatically connect the ehternet networks when they are plugged in? Is that wrong?

Thanks for taking the time to help me.

Re: Help setting up wifi... [SOLVED]

No, you need to pick *one* service (at least per NIC), ie. at the very minimum, restrict the dhcpcd service to enp0s31f6 (there's a big fat note about that in the network wiki)
Also you may want to look at https://wiki.archlinux.org/index.php/Ne … temd_units (since you likely want to switch the used NIC and route)
