3. Setup Guide
This section outlines the steps to set up your NEWFAST AX1800 WiFi 6 Range Extender.
3.1. Initial Placement
For the initial setup, it is recommended to plug the extender into a power outlet near your main router. Once configured, you can relocate it to an optimal position.
3.2. Powering On
Plug the extender into a standard electrical outlet. Wait for the device to power on and initialize. The LCD screen will display the current status.
3.3. Connection Methods
There are two primary methods to connect the extender to your existing Wi-Fi network: WPS (Wi-Fi Protected Setup) or Web Browser Setup.
3.3.1. WPS One-Click Setup (Recommended for quick setup)
- Plug the extender into a power outlet near your router.
- Wait for the extender to boot up.
- Press the WPS button on your main router.
- Within two minutes, press the WPS button on the NEWFAST AX1800 extender. The WPS indicator on the extender will flash during the connection process.
- Once the WPS indicator on the extender becomes solid, the connection is successful.

3.3.2. Web Browser Setup
- Plug the extender into a power outlet.
- Connect your computer or mobile device to the extender's default Wi-Fi network (e.g., "NEWFAST_EXT"). No password is required initially.
- Open a web browser and enter the default IP address or domain name (usually found on a label on the device or in the quick start guide, e.g., http://192.168.1.254 or http://re.newfast.com).
- Follow the on-screen instructions to create an administrator password and select your desired operating mode (Repeater, AP, or Router).
- If selecting Repeater mode, choose your existing Wi-Fi network from the list and enter its password.
- Complete the setup. The extender will restart, and its network name will change (e.g., your_network_name_EXT).
3.4. Optimal Placement
After successful setup, unplug the extender and move it to a location between your router and the Wi-Fi dead zone. The smart signal indicator on the LCD screen will help you find the best spot for maximum coverage and signal strength. Aim for a location where the signal indicator shows a strong connection to your main router.

4. Operating Modes
The NEWFAST AX1800 WiFi 6 Range Extender supports multiple operating modes to suit various networking needs.

Image 4.1: Visual representation of the three primary operating modes: Repeater, Router, and AP (Access Point) mode.
4.1. Repeater Mode (Default)
In Repeater mode, the extender wirelessly connects to your existing router and amplifies its signal, extending coverage to areas with weak or no Wi-Fi. This mode is ideal for eliminating dead zones.
4.2. Access Point (AP) Mode
In AP mode, the extender connects to your router via an Ethernet cable and transforms your wired network connection into a wireless access point. This is useful for adding Wi-Fi capability to a wired-only network or creating a new Wi-Fi network in a specific area.
4.3. Router Mode
In Router mode, the extender acts as a primary router, connecting directly to your modem via an Ethernet cable to create a new private wireless network. This mode is suitable if you do not have an existing router.
4.4. Using the Gigabit Ethernet Port
The integrated Gigabit Ethernet port (WAN/LAN) allows you to connect a wired device (like a desktop computer, smart TV, or gaming console) to the extender, providing a stable and high-speed internet connection. This port can also be used for AP or Router mode connections.
