NM may be allowed to access the whole filesystem but IWD's [[https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/src/iwd.service.in|default systemd unit file]] sets ''ProtectHome=yes'' which would cause connections to fail when trying to access certificate files in user home directories. If you intend to use ''iwd-config-path'' (**note distro maintainers**) make sure that NM and IWD have the same level of filesystem access, in their systemd unit files or otherwise. | ||

| - | If you've been using the NM + wpa_supplicant combo and switched to IWD it's possible to bulk-convert your existing network profiles to [[networkconfigurationsettings|the IWD format]], so that you can keep using them with the IWD backend. Especially useful for EAP (802.1X) networks. You will need to have the ''iwd-config-path'' mechanism enabled (see previous section). Optimally these steps would be done automatically by distribution scripts such as Debian's ''update-alternatives'' but they require a few changes to the profile settings so the user needs to be conscious this is happening.
