Test tools
Measure it, then see what it means
Each tool tests one part of your connection and tells you, in plain words, what the result says. Most use commands and apps already on your computer or phone. Nothing you paste leaves your browser.
Proves it is, or is not, the Wi-Fi
Home network test
Measure the speed between a device and your router, with the internet left out of it. Uses free, open-source tools.
Open the toolExplains a slow spot
Wi-Fi link check
See how strong the signal really is, which generation of Wi-Fi the device is using, and the speed that link can carry.
Open the toolFor lag and dropouts
Ping check
Paste the result of the built-in ping command. A chart shows whether delay is added inside your home or outside it.
Open the toolCompare rooms, check the plan
Speed and latency test
A quick built-in test, good to about 1000 Mbps, or type in results from any other test. Compares places side by side.
Open the toolFor port forwarding and NAT type
Public address check
Find out whether your home shares a public address with other customers, or has two routers in a row.
Open the toolNot sure which to use?
Start with the troubleshooter. It asks what is happening and brings in the right test at the right moment.
Coming later: open port check
A scan of your own connection from the outside, to show which ports are open to the internet. Because a tool like that could be misused, it will only run for a verified email address and a limited number of times.
