4. Setup Instructions
The COMFAST CF-WR306S is designed for a simple three-step setup process. The specific steps may vary slightly depending on the chosen working mode (Repeater, AP, or Router).
4.1. Repeater Mode Setup
In Repeater Mode, the device extends your existing WiFi signal, eliminating weak signal areas and dead spots.
- Power On: Plug the CF-WR306S into a power outlet near your primary router.
- Connect: Connect to the CF-WR306S's default WiFi network (usually named "COMFAST_XXXX" or similar) from your computer or mobile device.
- Configure: Open a web browser and enter the default IP address (e.g., 192.168.10.1) or domain name (e.g., cf.wifi.com) to access the setup wizard. Follow the on-screen instructions to select Repeater Mode, scan for your existing WiFi network, enter its password, and set a new name for the extended network if desired.
- Placement: Once configured, unplug the device and move it to a location halfway between your router and the area with poor signal. Ensure the indicator light shows a good signal strength.
4.2. AP/Router Mode Setup (Wired Connection)
In AP (Access Point) or Router Mode, the device connects to your network via an Ethernet cable and broadcasts a new WiFi signal.
- Power On: Plug the CF-WR306S into a power outlet.
- Connect Ethernet: Connect an Ethernet cable from your primary router (or a network switch) to the WAN/LAN port on the CF-WR306S.
- Configure: Connect to the CF-WR306S's default WiFi network or directly via another Ethernet cable to a computer. Open a web browser and enter the default IP address or domain name. Follow the setup wizard to select AP Mode or Router Mode, configure network settings (e.g., DHCP, static IP), and set up your new WiFi network name (SSID) and password.
The CF-WR306S can also provide wired internet access to devices like desktops, laptops, or IPTVs when operating in AP/Router mode, converting the wireless signal to a wired connection.
5. Operating Modes
The COMFAST CF-WR306S supports four main operating modes:
- Repeater Mode: Extends the range of an existing wireless network. Ideal for covering WiFi dead zones.
- AP (Access Point) Mode: Converts a wired network connection into a wireless one, allowing wireless devices to connect.
- Routing Mode: Functions as a basic router, connecting to an internet source (e.g., modem) and creating a new private network.
- Bridge Mode: Connects two separate networks, often used to connect wired devices to a wireless network.
You can switch between these modes via the device's web-based management interface. Refer to the setup instructions for accessing this interface.
6. Maintenance
- Firmware Updates: Periodically check the COMFAST official website for firmware updates to ensure optimal performance and security.
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or aerosols.
- Ventilation: Ensure the heat dissipation holes are not obstructed to maintain efficient cooling and stable operation.
- Reset: If the device is not functioning correctly, you may perform a factory reset by pressing and holding the reset button (usually a small pinhole button) for about 5-10 seconds while the device is powered on. This will revert all settings to their factory defaults.
7. Troubleshooting
- No Internet Access:
- Check if your primary router has internet access.
- Ensure the CF-WR306S is properly connected to the primary router (wired or wirelessly).
- Verify the settings in the web-based management interface, especially the WAN/Internet settings in Router mode or the upstream network selection in Repeater/AP mode.
- Try restarting both your primary router and the CF-WR306S.
- Weak Signal from Extender:
- Relocate the CF-WR306S closer to your primary router. The ideal location is halfway between the router and the area needing coverage.
- Ensure there are no major obstructions (thick walls, metal objects) between the extender and your devices.
- Check the signal indicator light on the device (if available) to ensure it's receiving a strong signal from the primary router.
- Cannot Access Setup Page:
- Ensure your device is connected to the CF-WR306S's WiFi network (or via Ethernet).
- Verify the IP address or domain name entered in the browser is correct (e.g., 192.168.10.1 or cf.wifi.com).
- Clear your browser's cache and cookies, or try a different browser.
- Temporarily disable any VPN or firewall software on your computer.
- Connection Drops Frequently:
- Check for interference from other electronic devices (microwaves, cordless phones).
- Ensure the device is not overheating (check ventilation).
- Update the firmware to the latest version.
- Try changing the WiFi channel on your primary router or the extender to avoid congestion.
8. User Tips
- Optimal Placement: For best results in Repeater mode, place the amplifier where it can receive at least 50% signal strength from your main router. This ensures a strong signal for re-transmission.
- Network Naming: When using Repeater mode, you can choose to keep the same network name (SSID) as your main router for seamless roaming, or create a new SSID (e.g., "MyHome_EXT") to easily identify the extended network.
- Security: Always use a strong, unique password for your WiFi network and the amplifier's administration interface.
