Alan, my Verizon gets 160 at the most so far. Xfinity is 300+.
You may be able to improve that number by simply moving the router to a different location. I get consistently better speeds when my router is next to a north facing window. I'm guessing because it provides a more direct route to the nearest 5G tower.
