Years of problems with X1 DVRs fixed by using Wireless DVR

I had daily scrambled images, freezes, stop & crash to DVR recordings list using 3 cable based X1 Xfinity cable boxes on certain shows on Fox. They replaced the box 3 times. Last guy recommended a little Xfinity Wireless Cable Box and now everything perfect! Glad to stop using the Xfinity App as forwarding through ads with no visuals was as painful experience. I pay for maximum internet speed getting a technical 2100 mbps Download speed to router. 1100 on phone tests.
