Please help! Mew wifi and my xbox ain't working

So I got a new ultra hub 7 wifi router and I'm having trouble with my xbox's, my xbox 360 straight up refuses to connect to it, saying connection to the router failed and the rest says blocked, my series x connects but says NAT type strict and upnp not successful, but I have turned the upnp on, it looks like I'm connected on the series x dashboard but I can't load anything and when I launch a game it's saying do I own this game or app, I've never had a issue with the old grey router
