Comcast upgraded my speed because they thought google fiber was coming, and as part of that, has been bugging me to upgrade my modem. Multiple phone calls and emails. I own the modem and have never rented from them. And I haven't bothered upgrading because the download speed is basically fast enough already and I don't think it would improve the upload speed.
