1️⃣ Check the Physical Connection

• Make sure the Ethernet cable is firmly plugged into both the device and the router/switch.
• Look for LED lights near the Ethernet port:
  • ✅ Blinking light → active connection/data transfer
  • ⚠️ No light → possible cable or port issue

2️⃣ Try a Different Cable

• Swap the cable with a known good one.
• Ethernet cables can fail internally even if they look fine.

3️⃣ Try a Different Port

• Plug the cable into a different port on the router or switch.
• Sometimes ports fail while the device is fine.

4️⃣ Check Network Settings

• Ensure your device is set to obtain an IP automatically (DHCP).
• Alternatively, verify that a static IP is configured correctly if used.

5️⃣ Restart Devices

• Restart both your router and the device.
• This can resolve temporary network issues.
