To configure iwd, you should use <code>networking.wireless.iwd.settings</code> option. An example configuration, which enables IPv6 and automatic connection to known networks, would be similar to: | |||
<syntaxhighlight lang="nix"> | |||
{ | |||
networking.wireless.iwd.settings = { | |||
Network = { | |||
EnableIPv6 = true; | |||
}; | |||
Settings = { | |||
AutoConnect = true; | |||
}; | |||
}; | |||
} | |||
</syntaxhighlight> | |||
For a detailed and up-to-date list of available settings, please reference the [https://git.kernel.org/pub/scm/network/wireless/iwd.git/tree/src/iwd.network.rst network daemon configuration docummentation], from kernel Git repo. | |||

When using certain chipsets, such as the Qualcomm qcncm865<ref>https://community.frame.work/t/guide-successful-wi-fi-7-802-11be-on-framework-13-amd-with-qualcomm-qcncm865-and-arch-linux/44723</ref>, you need to use legacy EAPoL packets<ref>https://lkml.org/lkml/2020/10/14/1101</ref> to prevent a disconnect loop. In <code>iwd.service</code> this issue shows up as:<syntaxhighlight> | |||
