Ps5 has spotty connection w/ NAT type failure

My Ps5 struggles to connect to the internet and after repeatedly trying it finally will. Sometimes I have to forget my network and re-enter it. When it finally connects it often has a NAT type failure. So in order for me to get that to work I have to change it the DNS to cloud fare (1.1.1.1 and 1.0.0.1) and that will get it to work for a little bit but it will soon go back to connection problems. Sometimes it will connect to the internet but I still will have to try over and over after starting a game to login to thier online servers. Other times it just doesn't connect at all. Then I have to start the process I mentioned at the beginning all over again. This just seemed to start happening randomly. I've had Xfinity for about 3(ish) months and haven't had any problems until now. I do have a Netgear modem/router but it has been working fine until now. This is what I have tried to no avail:

-set up port forwarding

-reset router (over and over)

-reset ps5 from safe mode

-tried rebuilding database on ps5

-tried switching back and forth between LAN and WiFi

I know it's Xfinity connection because I connect my phones hotspot(Tmobile) to the PS and it works just fine. All my other devices seem to be working fine. At times they do seem a little slow but they are working. I have no idea what to do. This is one of the main things I use my internet for.
