# 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**.

**Available diagnostic tools for all Pearl Nanos:**

- **Connectivity status**: Display the status of critical network connections and features like 802.1x.

To troubleshoot networking issues yourself, try to ping the IP address of your Pearl Nano 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 Nano or contact Epiphan support.
