In the last couple days, my internet dies at around 12:30AM every day, my setup is a modem that goes through a router that goes to a voip box. I've tried resetting/unplugging/flashing...etc. everything and the only thing that works is to plug the modem into the phone box, then somehow, the phone box gets connection (if I tried plugging a computer directly to the modem, it doesn't work), but when I try plugging my router to the phone box it doesn't work, I have to unplug after it gets connection and return to my original setup. This is extremely annoying and took me a while to figure out. Which part of my setup is faulty and what can I do about it? I think it's the modem having trouble assigning ips, but when I try changing my ip on my computer, it doesn't work.
