[SOLVED] Copy wifi config to new install

Synopsis: Copy the Arch ISO wifi profile located in /etc/netctl to the target and since it will reference the kernel version of the wifi device name I'll hack the target profile to reference the netctl version of the device name.

How do I copy the wifi config used during a new install to the target so that it automatically connects on first boot into the new system?

What are you using to control your wifi?

I connect using wifi-menu.

Re: [SOLVED] Copy wifi config to new install

wifi-menu is part of netctl and netctl uses profiles to store/setup connection data.

https://wiki.archlinux.org/index.php/Netctl has info where those profiles are located .

Re: [SOLVED] Copy wifi config to new install

Easy enough to copy the wifi profiles created by wifi-menu located in /etc/netctl to the new install then activate the wifi device like so...

systemctl enable netctl-auto@<device>.service

However, my wifi device shows up as wlan0 during the install but changes to wlp6s0 when I boot into the new system.

How do I get both the install wifi device and the new system wifi device to use the same device name?

The installation iso uses iwd which is configured to use the names provided by the kernel ( eth0 , eth1 , wlan0 etc ) .

On an installed archlinux systemd-udev renames the devices.

Re: [SOLVED] Copy wifi config to new install

Very interesting reading.  This is ugly and I think creating my own device naming rules is a bit extreme so I'll just hack the profile copied to the new install to reference the netctl version of the wifi device name that will show up there.

This in not scalable I know but it will do for now.
