What would cause my router to disconnect in the early hours of every morning

Hi Guys

My router is disconnecting in the early hours of every morning.  Ranges from between 1am and 4.30 am, just once.  No one is using it at this time but it is trashing my speed.

Any thoughts appreciated.

How long has it been doing it for? Have you tried running routerstats to see if it is noise on the line?

Hi Lance.  Only for the last six weeks or so.  Before then it was fine.  Haven't done anything different in that time so a bit mystified really.  No, I haven't ever used Routerstats.
