Yes I am used to some of their peculiarities ;-)

OK but just to note that it's the other way round as per my comment:

So if the router is AlwaysOn and Libre is auto=add then no messages and
all is quiet on the Western Front.

If I put Libre into auto=start we have a scene resembling something from
the Somme in the logs with it continuously reconnecting :-)

I can live with it with auto=add, and will be ousting said routers as
soon as I can (because talking to their tech support is
errrrr........!), but I was just curious as to what was going on and why.
