We're still off all this week.
I got around to replacing the couple of switches below as I have used all the ports and they don't make these stackable ones any more. So we went from these two 8 port switches
While I was at it the router also died. Maybe as a result of swapping out the two switches although it should make no difference. I ended up buying a new one. They only seem to last a couple of years. I had to spend a bit of time configuring things to get it working.
