Fios router, reboots EVERY night at 2am, can it be stopped from doing so?

Hi,

   At 2am EST the Quatum router does a reset, and it cause some anoyances. It's only been rebooting for around 3 weeks, and it's like clock work at 2am.

Can I get it like it use to be with no auto-reboot at 2am?

Thanks in Advance,

Rick
