In Germany most internet connection have a clause that requires regular reestablishing with get's you a new IP address. It's in the contracts because the changing IP address makes it harder to run a server behind a home connection.
The advantage of a changing IP address that it's a lot harder to track you for random websites.
It makes sense for the router to choose a time in the night where the connection isn't used to do the reconnecting. Otherwise the ISP would on it's own choose the timing which might be worse.
If your router however does this when you aren't sleeping see if disabling the feature helps.
I think you may have misunderstood. I'm talking about my router, which is a separate device from my modem. I have never observed the router rebooting to fix a problem, and have on several occasions observed the reboot to cause a problem. I just want to know if there is something nonobvious going on that will cause problems if the router does not reboot once a week, keeping in mind that it is a separate device from the cable modem.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
