# Run diagnostic tests using the device screen

You can access useful diagnostic tools from the device screen when you select **Settings > Network** and select **Connectivity Status**. The Pearl-2 has additional diagnostic tools found on the second page under **Network Tools**.

**Available diagnostic tools for all Pearl-2s:**

- **Connectivity status**: Display the status of critical network connections

- **Ping**: Test if the Pearl-2 can reach a specified destination server on the network. Not all networks support ping.

- **Trace route**: Trace the route that packet traffic takes to get from the Pearl-2 to a specified destination server on the network. Not all networks support traceroute.

- **Bandwidth test**: Display the available upload and download bandwidth speed in Mbps up to a maximum bandwidth of 1000 Mbps.

- **Domain name resolution**: Confirm that the Pearl-2 can resolve a Fully Qualified Domain Name (FQDN) using the DNS server that is configured for the Pearl-2.

- **Probe**: Check if Pearl-2 can establish communication to a specific port on a network host using a network protocol that you specify. Supported network protocols are: TCP, HTTP, HTTPS, RTSP, RTMP, and RTMPS.

To troubleshoot networking issues yourself, try to ping the IP address of your Pearl-2 or do a traceroute to a server such as 8.8.8.8. If you are unable to resolve your networking issues, contact your network administrator and provide them the IP address and MAC address of your Pearl-2 or contact Epiphan support.
