<p>The LAN lights indicate the connection between the router and devices connected via Ethernet cables. If these lights are not lit, check the cable connections and try different ports. If the issue persists, inspect the Ethernet cables for damage or try using new cables. Additionally, verify the network settings on connected devices to ensure compatibility with the router. For wireless connectivity issues, focus on the Wi-Fi indicator lights. If the 2.4GHz or 5GHz Wi-Fi lights are off, access the router's web interface using a device connected via Ethernet.
