You may want to add the following line to config wifi-iface 'default_radio' section

        option network 'I_WIFI5'

thank you, this is it, and it is probably a bug in the luci that I have configured it with and this value did not appear there

Please then open a pull request at https://github.com/openwrt/luci with reproducing steps. Thank you.

Also remove option ifname 'wlan0', as documented in the Routed AP article.
