# Ping & Traceroute

We can use the pre-built tools and web terminal to test the internet connection. After logging in to the router admin panel, go to "Network > Diagnostics."

### Ping

Use the "Ping" tool to ping a public DNS server or website to test latency. If returning a "Bad address" error, the internet connection is not working. If ping results have high latency, such as more significant than 300ms, the Internet speed is not fast.
