4.2 Initial Configuration

To configure your router, you can use a web browser:

1. Connect to Router: Connect your computer or mobile device to the router's Wi-Fi network (SSID and password are usually found on a label on the bottom of the router) or via an Ethernet cable to a LAN port.
2. Access Web Interface: Open a web browser and enter the default IP address: 192.168.10.1.
3. Login: Enter the default username and password. As indicated on the router's label, the default username is admin and the default password is admin.
4. Follow Setup Wizard: The router's web interface will typically guide you through a quick setup wizard to configure your internet connection, Wi-Fi name (SSID), and password. It is highly recommended to change the default Wi-Fi name and password for security.

4.3 Mesh Network Setup

The CF-WR631AX V2 supports easy mesh wireless expansion. To set up a mesh network with multiple routers:

1. Primary Router Setup: Set up your first router as described in Section 4.2. This will be your main mesh node.
2. Add Secondary Routers: Place additional CF-WR631AX V2 routers in areas where you need extended coverage.
3. One-Button Interconnection: Press the MESH button on the primary router, then press the MESH button on the secondary router(s) within a short period (refer to the specific timing in the on-screen instructions of the web interface). The routers will automatically connect and form a seamless mesh network.
4. Verify Connection: Check the indicator lights on the secondary routers to ensure they have successfully joined the mesh network.

6. Maintenance

6.1 Firmware Updates

Regularly check for firmware updates on the Comfast official website. Firmware updates can improve performance, add new features, and enhance security. Follow the instructions provided with the firmware update carefully.

6.2 Cleaning

To clean the router, gently wipe it with a soft, dry cloth. Do not use liquid or aerosol cleaners, as they may damage the device.

6.3 Optimal Placement

Place the router in a central location in your home, away from obstructions like thick walls, metal objects, and other electronic devices that may cause interference. Elevating the router can also improve signal spread.

7. Troubleshooting

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

• No Internet Connection:
  • Check if the WAN cable is securely connected to both the router and your modem.
  • Restart your modem and then your router.
  • Verify your internet service provider (ISP) connection status.
• Weak Wi-Fi Signal / Dead Zones:
  • Relocate the router to a more central position.
  • Adjust the antennas for better coverage.
  • Consider adding another Comfast mesh router to expand coverage.
  • Ensure there are no major obstructions or sources of interference near the router.
• Cannot Access Router's Web Interface:
  • Ensure your device is connected to the router's network (wired or wireless).
  • Verify you are using the correct IP address: 192.168.10.1.
  • Try clearing your browser's cache or using a different browser.
  • If you forgot your login credentials, you may need to perform a factory reset (see below).
• Lagging or Slow Speeds:
  • Check if multiple devices are heavily using bandwidth (e.g., streaming 4K video, large downloads).
  • Ensure your internet plan supports the speeds you expect.
  • Update router firmware.
• Factory Reset: If all else fails, you can perform a factory reset. With the router powered on, press and hold the RESET button (located on the back panel) for approximately 5-10 seconds until the indicator lights flash. The router will restart with default settings (default IP: 192.168.10.1, User: admin, Pass: admin).

8. User Tips

• Change Default Credentials: Always change the default Wi-Fi name (SSID) and password, as well as the router's login password, immediately after initial setup for enhanced security.
• Leverage Mesh for Large Homes: For larger homes or multi-story buildings, utilize the mesh networking feature with additional Comfast AX3000 routers to ensure seamless and strong Wi-Fi coverage everywhere.
• Utilize Gigabit Ports: For devices that require maximum speed and stability (e.g., gaming consoles, desktop PCs, network-attached storage), connect them directly to the router's Gigabit LAN ports.
