Motorola MB8600 modem with Asus AC2900 wifi router. No internet on the router.

Hi Maximus, I ran some tests on the modem which caused it to reboot temporarily, and I did not find any issues on our end. As you've indicated that you are able to bypass the router and obtain a hard-wired connection directly through the modem, we recommend contacting the manufacturer of the wireless router for additional support. -Kevin M.
