5. Operating Instructions

Dual-Band Wi-Fi:

The EA6400 is a dual-band router, meaning it broadcasts two separate Wi-Fi networks: 2.4 GHz and 5 GHz. The 2.4 GHz band offers wider coverage and better penetration through walls, while the 5 GHz band provides faster speeds and less interference for devices closer to the router.

• 2.4 GHz Band: Ideal for older devices, devices further from the router, and general internet browsing.
• 5 GHz Band: Best for newer devices, high-bandwidth activities like streaming HD video, online gaming, and large file transfers, especially when closer to the router.

Linksys Smart Wi-Fi App:

Manage your network from anywhere using the Linksys Smart Wi-Fi App. This app allows you to:

• View connected devices.
• Set up guest access.
• Prioritize devices for optimal performance.
• Manage parental controls.
• Perform speed tests.

Gigabit Ethernet Ports:

Utilize the four Gigabit Ethernet ports for wired connections to devices that require maximum speed and stability, such as desktop computers, network-attached storage (NAS) devices, or smart home hubs.

NFC Simple Tap:

For NFC-enabled devices, simply tap the Simple Tap card (included with some models or available via the app) to easily connect to your home network without manually entering credentials.

6. Maintenance

To ensure optimal performance and security for your router:

• Firmware Updates: Regularly check for and install firmware updates through the Linksys Smart Wi-Fi App or the web interface. Updates often include security patches and performance improvements.
• Placement: Keep the router in an open area, away from obstructions and other electronic devices that may cause interference.
• Security: Use a strong, unique password for your Wi-Fi network and router administration. Enable WPA2/WPA3 encryption for maximum security.
• Cleaning: Periodically clean the router's exterior with a soft, dry cloth to prevent dust buildup in ventilation areas.

7. Troubleshooting

If you encounter issues with your router, try the following:

• No Internet Connection:
  • Check all cable connections between the modem and router.
  • Restart your modem and router by unplugging them for 30 seconds and then plugging them back in.
  • Verify your Internet Service Provider (ISP) is not experiencing an outage.
• Slow Wi-Fi Speed:
  • Ensure your devices are connected to the appropriate Wi-Fi band (5 GHz for faster speeds, 2.4 GHz for better range).
  • Move closer to the router to improve signal strength.
  • Reduce the number of devices actively using the network, especially for high-bandwidth tasks.
  • Check for firmware updates.
• Cannot Connect to Wi-Fi:
  • Double-check your Wi-Fi network name (SSID) and password.
  • Try restarting the router.
  • If using WPS, ensure the device is compatible and the WPS button is pressed correctly.
• Factory Reset: If all else fails, perform a factory reset by pressing and holding the Reset button on the rear panel for approximately 10 seconds. This will erase all custom settings, and you will need to reconfigure the router.
