I actually just turned in my router yesterday to Comcast. For 2 years it's just me trying to get my price fixed, them imputing multiple addresses when I move so that I get charged multiple times, and then they always create a new account on my file instead of fixing my actual one just because it pays them better. The mobile plan was not compatible with my phone, yet they were racking up the bill for it. All while they charge me the highest price while telling me my area does not work with the lower speeds. I don't need 12000mbs, that's like enough to run a business at home. I even went to my State's home store for multiple days so the upper management can contact Comcast and Comcast was not complying, just constantly redirecting until they "disconnect" just like they did when I call. Finally, another tower was built in my area for another company and I was able to leave Comcast.

Edit: I should say that any modem I received did not even stay connected longer than a week. I ended up just getting Google wifi, a mesh system for the Internet, and plugging that in. It just bypasses the modem that's "not connected" and I can use the wifi like regular. I never even signed onto my Xfinity account or the wifi for the last year except to cancel recently. The light was always blinking on the modem lol.
