xbox 360 will not connect network

I moved into a new house and got a new router/modem. Now my xbox 360 will not connect to the wireless. I have done every troubleshooting thing that has been offered. Yes I have done https://www.xfinity.com/support/articles/connecting-your-smartphone-or-tablet-to-your-home-network?linkId=129825532. I have turned off the WPA. I have tried to port forward but it doesn't connect so I can't with the UI that is available. I have gave it a static IP. I have added the IP and DNS to the xbox in manual mode.

It connects just fine using Ethernet and with a hotspot on my phone. I have 3 xbox 360 and none of them will connect using the xfinity router/modem Everything else in the house connects just fine. I have changed the password, I have turned off the 5GHz.

I went through support but they just had me reset the modem and then unplug it and plug it back in.
