I'd force a change to date/time in your laptop to see if it strictly has something to do with "mornings" as far as the laptop is concerned.
You could also try a different router.
These two tests should allow you to determine if its settings within the laptop or the router. Then you can at least focus on only one culprit.
Once you have it narrowed down you can check things like drivers and any possible settings.
Maybe laptop parental settings that turn off network connectivity between certain hours, etc.
