Chromecast deserters, have you found an alternative that makes you happy?(r/Chromecast)
I’ve never had an issue, but I have never had an Xfinity gateway (which you’re paying $10 a month for. This modem is $70, so you’d be ahead after 7 months.)
I just went on vacation and brought the Chromecast along and had zero issues with it. We watched Netflix before we went to bed and it connected instantly and had zero skipping or lag. You might want to reevaluate your home network and see if you can improve it before giving up.
