NetScope

Find out why your Wi-Fi feels slow.

What it does

Scores your connection from latency, jitter, packet loss, DNS response time and throughput.
Times your router separately from the internet, so you can tell a bad Wi-Fi link from a bad line.
Lists what else is on your network, using Bonjour and a scan of your own subnet.
