The restart was needed to get rid of the existing leases. (I.e. just
unchecking DHCP didn't have the effect I was after.)

If that happens I'll be very proud ;-)

Ooh, even prouder - as then they can teach me something!

But going back to the topic of my original off-topic question: if I had
the router configured to allow certain handsets to only use internet
between 4pm and 5pm, and 8pm and 9pm, when it gets to 5pm they will
shrug and get on with homework. You can cross a busy road when the
lights are red, but the effort/risk is more than the benefit so just
about everyone will wait for the green light almost all of the time. It
is easier to go with the flow, especially when you know it is what you
are supposed to be doing.
