Did you know that 100 Mbps that’s advertised is NOT 100 Megabytes per second? Nope. It’s Megabits. This means you are getting roughly 12.5 megabytes per second if you are in fact hitting peak speeds. So those of you on DSL or a slower connection are likely only getting 1 or less Megabytes per second. This means downloads, web surfing, streaming, etc are all going to be painfully slow as the internet gets larger. If you’re on wifi, it’s going to be even less than the advertised due to loss of latency. Also, if you have a lot of devices (phones, tvs, computers, printers) this will decrease speed as well.
Make sure you’re purchasing internet speeds based on what kinds of activities you are doing online. If you’re an avid streamer, go for at least 50 Mbps down. If you’re an avid streamer with a lot of people in the house, 150 Mbps. Bottom line, start small, and if you determine you’re having slowing issues, move up.
