I altered the conf file and added the noipv6rs option.

That has stopped the flooding of the "no routers" messages.

However, these messages are now being written to daemon.log:-

There seems to be a bit of a disconnect relating to network settings.
Some weeks ago, systemd started writing out a resolv.conf file without
the nameservers that I use. This was fixed via an include file with the
correct IP addresses and that fixed that particular issue.
NetworkManager writes a correct resolv.conf file into
/var/run/NetworkManager.
The contents of /etc/network/interfaces seems to be ignored and a dhcp
lease appears to be acquired via whatever is connected. So, if I'm in a
hotel somewhere and manage to overcome rfkill switch issues so as to
use their wi-fi, I'm able to connect even though there is no entry for
wlan0 in /etc/network/interfaces. 

Thanks,
Rob
