archinstall's "Copy ISO network configuration", which a user who connected with iwctl may pick, turns on iwd and systemd-networkd. CoreDesktop then turns on NetworkManager too, and after a restart two services fight over the Wi-Fi card. system/wifi.sh disables iwd and systemd-networkd, without stopping them, when NetworkManager is enabled and isn't set to use iwd itself. install.sh runs it, and a migration runs it on existing machines. The README tells users to choose NetworkManager in archinstall. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Purpose : Leave Wi-Fi to NetworkManager alone. archinstall's "copy ISO network
|
|
# configuration" turns on iwd and systemd-networkd, so a machine set
|
|
# up with iwctl from the Arch ISO can have them running alongside
|
|
# NetworkManager, which CoreDesktop turns on. Then two services fight
|
|
# over the Wi-Fi card: connections drop, or Wi-Fi is missing from
|
|
# GNOME.
|
|
#
|
|
# This disables iwd and systemd-networkd without stopping them, so the network
|
|
# stays up until the next boot; after it, NetworkManager runs Wi-Fi and wired
|
|
# connections. iwd's saved Wi-Fi passwords don't carry over: choose the network
|
|
# once in GNOME's top-right menu.
|
|
#
|
|
# Changes nothing when NetworkManager isn't enabled, or when it is set up to
|
|
# use iwd itself (wifi.backend=iwd in /etc/NetworkManager/conf.d/).
