I have followed a lot of discussions about WiFi speeds but haven't noticed a lot of details or photos showing where or how they got their stats. I thought I'd post what I came up with for what is throughput - speed of connection to a router & bandwidth - speed of Internet connection from the router. The stats and photos below came form my SP3 i7 8 gig 512 gig computer. These tests were performed by logging into my network where I work. The network is shared by about 100 people, most of which or connected via Ethernet.
