Not a problem for Apple TV. How is the quality, on that? (Buffer, crash, time for full hd/4k,- I ask this because it reflects on their servers ability to handle high usage times)
House full of Apple products? My company(ISP) bills people for that every day. Not a problem for everyone, but high usage of photos, vids, etc, Apples back up/update procedure can seize the download. We have people going from 50 meg fiber to 100 Meg, thinking it will fix the problem. It doesn't. They need to back up their Apples at a specific time, or purchase a faster UPload speed.
Symmetrical service is more $$. Know your needs before throwing away $$, or fix your home network problems.
Have a photographer buddy, whose business is photo/video editing. Was on 200 Meg Comcast. Suggested cheaper 75/50 Meg fiber. For his work related stuff, it wound up being 5 times faster for him. (Uploading to his server/clients) Don't believe the advertisements. The math is fuzzy, on purpose. Cable shares bandwidth. When you push the button you get precedence, for about 30 seconds, or so. (So you can pass an internet speed test,) You take it from your neighbors. Then you fall back into the actual network capability. Can be a great choice , depending on how your neighborhood is engineered. You're $$ may have been equly spent, buying a lesser service.
The same holds true for streaming. It only takes a minute to understand your needs. IF you are an apple household, and experiencing streaming issues? Power down your Apple products. If you are streaming through Xbox, their servers/apps are hot garbage for anything other than gaming. There are simple solutions.
** Full disclosure. I work for a company that was formerly owned by Verizon FiOS. I primarily deal with engineered/designed circuits. Corporate backbones, cell tower connectivity. I occasionally deal with residential streaming issues. See - why we have Netflix drains. (And why everyone else does)
Apologies for geeking out about this stuff..
