My R8000 is not sending a wireless signal

My Nighthawk X6 does not show up on any wifi lists. When I use a wired connection it works but even when typing in 192.168.1.1 into my browser, I cannot access the settings. I also tried going into my command prompt to find my ip adress and the ip listed there also did not work. It is linked to a Comcast business modem which is in bridge mode.
