Network Devices – Diagnostics

Written by Sunny

Overview

The Diagnostics page allows administrators to perform device-level network troubleshooting directly from the Cloud Controller. It provides built-in tools to test connectivity, routing, DNS resolution, and wireless environment visibility for a selected network device.

This page helps isolate network, ISP, DNS, and device-related issues without requiring local access to the device.
