Or, if can’t avoid it, use it but you cut the wifi and other crap and connect your own router on it.

I use the Turris Omnia since a good decade now, still supported, open source based, i can put some services on it (vpn, ssh, nas, speedtest, …), put some traffic rules / ports redirection, firewall, dns, hostname/ip per mac address, pihole, wifi conf, etc…

If i switch to another ISP, I change the box and everything rework quickly…
