AC1900 R7000 IP configuration invalid issue on multiple devices

Newest firmware. Connected to a cable modem. Connected an iPhone and an Xbox and then every other device cannot get a valid IP configuration including phones, Macs, and Windows computers.

I reset the router to no avail. After resetting the modem, another laptop got connected. But now, the Xbox will not connect. It seems that only two devices are connecting at a time. What can I do to solve this problem?

Figured it out. My modem was just a gateway, not a router/gateway. The router was by default in AP mode, and I had to set it to router mode.

Check the lan settings and make sure its capable of giving out more than 2 IP addresses ?

  The LAN setup is grayed out in my settings. I cannot get into it. Why would this be?
