My wife and I are the only two in our household. We get all of our TV content through streaming providers like Hulu, Netflix, ESPN+, and Disney+. My wife usually only streams content in 720/1080 HD. I occasionally stream a sporting event in 4K. We are almost always streaming different programs at the same time. I sometimes watch TV while also playing World of Warcraft. I also have my Broadcastify feed up 24/7. Would Spectrum's 100 Mbps speed be enough for our needs? The 400 Mbps is $20 more per month.
