In this video I demonstrate how ISPs sell you more bandwidth than you actually need, when what you're really looking for is a reliable network which carries your traffic with minimal latency and loss. I dive into the three main factors which make up connection quality (bandwidth, latency and loss), explain why speedtests are almost useless, and show you how to estimate how much bandwidth you actually need. Finally, I preview Netprobe, a simple and effective tool I wrote for monitoring your internet performance at home (and totally free and open source!)
