Wi-Fi: rc.conf(5) NOAUTO, service(8) netif start wlan0 and resolvconf(8) after disconnecting from a wired network

FreeBSD 13.0-RELEASE-p3 starts with a wired connection to a Belkin router.

re(4)

service netif start wlan0 gains the required address from the required wireless router, using DHCP.

I disconnect the network cable, interface re0 disappears, I'm left with the /etc/resolv.conf that was generated by resolvconf(8) for the (Belkin) router that is no longer available.

Neither resolvconf -u nor service resolv restart leads to /etc/resolv.conf gaining the required update.

What must be done, for resolvconf(8) to write what's appropriate for the wireless router?

Maybe some of my problems with networking will disappear, or ease, as a result of these commits fours hours ago:


  • the latter fixes a few rc scripts by using startmsg.
FreeBSD bug 255207 – rc_startmsgs: Silence "Starting ..." messages is now Closed FIXED.

256957 – Wi-Fi: rc.conf(5) NOAUTO, ifconfig(8) up and unwanted WLAN connections to open networks remains open.

Understanding the routing service, /etc/rc.d/routing (2022-01-28), where dnabre helped me to realise that:

/etc/rc.d/routing isn't a service. …
 
Thanks, I've seen the word lagg in the past, however I'm extremely wary of experimenting with anything more complicated until there's a fix for automated unwanted connections to open networks. It's not my idea of good security.
