PS5 and XB8-T

I have read so many posts about this topic. I have tried all the steps multiple times. Comcast still has no solution for making the PS5 work on their modems? Has anyone figured out a workaround for this? It’s been YEARS! I have tried wired and wireless, port forwarding, Upnp - nothing works. The services all fail. Images are broken. PS store fails to load.

has anyone figured this out after all these years of frustration?
