This afternoon it's decided to start working again on 2 laptops and one android phone. I daren't connect anything else at the moment! But for how long is anyone's guess.
Over the last 24 hours I have:
None of the above changes made an immediate impact, but maybe the effect of one change was delayed. Mind you I've also been in this position last week, where it all started to work and then suddenly stopped.
I will try limiting access to a couple of laptops for a week and see how it goes.
But just to say many thanks for all the replies.
Regards
Stuart
