Caution: you should reboot after this, or at least kill the dhclient
you've started and clean up the file it creates in /run/resolvconf/interface/

Otherwise you may discover the Internet is slow (3-4 second pause before
any web page opens, because there's a DNS server for the wrong LAN at
the top of your /etc/resolv.conf) and/or doesn't work at all (because
the DHCP lease renewals somehow get routed by your home router and
confuse your ISP's gateway into kicking your entire home network
offline).

That was a fun few hours of network issue debugging I'm never getting
back.
