100/20 is definitely an improvement, and is probably a reasonable minimum bar to set. I'm sure most of us have much higher speed connections, but I know I rarely take my 1Gb pipe over 10% of that... Heck, 2 TVs streaming 4k during a zoom call would be fine on 100Mb...
> 4k during a zoom call would be fine on 100Mb Not sure what bit rate TV is at, but one 4K YouTube stream can take up to 68Mbps, and 8K even more. We're on 400Mbps, and even then I manage to block internet for others when I download a large file at full speed.
That's more of a router/QoS issue. A large download shouldn't negatively affect quality for other uses, especially VoIP. If the place you're downloading from has a pipe bigger than yours and can saturate your bandwidth you're going to need to implement some kind of rate-limiting/queue management.
