Thanks for your considered reply Neil I think you're right in that it may not be every night - and I had to do it one night when I was awake, then again in the morning.
I have been through the network assistance wizard (whatever it's called) and each time the suggested solution is to switch the modem off and on again - which does work. I'll try your other suggestions and report back, probably tomorrow if it follows it's mostly usual pattern. I wonder if this is particular to the latest iMacs?
