Can you show output of

ubus call system board

In general ancient versions have known security issues, while you can have one wired to private network, avoid priming up wifi.

Outline of process here:
https://openwrt.org/docs/guide-user/network/wifi/wifiextenders/bridgedap
https://openwrt.org/docs/guide-user/network/wifi/guestwifi/start

(you have to run guest backhaul in a vlan over ethernet or over greatp for wifi backhaul)

AP is connected via LAN cable

Well, it is long unsupported due to low storage/ram. Likely vlan guidance works but wifi opens known vulnerabilities fixed only in later releases.
