I have Xfinity's sliced off rectangle of a modem/router so my family was pretty amused by the new Xbox series x. Xfinity now wants us to upgrade to the xb7. It's a white sliced off rectangle and has 4 Ethernet ports instead of 2.
Unfortunately, it's the reason my internet isn't as powerful as it could be. I posted this on reddit too (my most popular post as well!) and everyone was saying that owned the same thing that the router sucks.
