That’s why I wrote an Ansible playbook, to configure and update my router and access points. It’s nice having this almost as infrastructure-aa-code, with all configuration changes under version control with a clear commit message. The script is available at https://github.com/danielvijge/openwrt-configuration-ansible, but do make some changes to match your configuration. I keep my network configuration (inventory file) in a separate, private GitHub repo, as that contains passwords etc.
