COMFAST Wireless Expander/Repeater Quick Installation Guide

1. Introduction

1.1. Product Structure:

The device is a compact wireless expander/repeater. Key components and indicators are:

• Power indicator: Blue light is always on when the device is powered.
• Network port status light: Blue light is always on to indicate normal network cable access.
• WiFi status light: Steady red indicates a weak WiFi signal; steady blue indicates a strong signal; steady green indicates the device is connected to WiFi.

Device Ports: The device features a LAN/WAN port labeled 'WAN/LAN'.

Reset Button: A WPS/RESET button is located on the device.

Tip: Hold down the RESET key for 5 seconds to reset the device to factory settings.

2. Relay Installation Steps

2.1. Power and Initial Connection:

Plug in the power supply and wait for 1-2 minutes. Connect your device to the WiFi signal named 'COMFAST_XXXX_2G' or 'COMFAST_XXXX_5G'.

2.2. Login and Password Setup:

Click the WiFi signal to open the login interface. Enter 'admin' in the password box and click 'Set Password'.

(Screenshots show the mobile WiFi connection list and the login page with fields for password and a 'Set Password' button. An English language selection option is visible.)

Tip: When logging in for the first time, the login interface usually pops up automatically. If it does not, manually open a mobile browser and enter '192.168.10.1' in the address bar.

2.3. Repeater Configuration:

After setting the password, the device enters the repeater scanning page. Select the SSID of the desired WiFi network (the 'trunk' or main router), enter the upper router's password, and click 'Save'. The repeater will then reconnect to the wireless network. The expanded signal name will be the original WiFi name with a '-2G' or '-5G' suffix appended.

3. Introduction to Working Mode

3.1. Available Modes:

The software supports four working modes: Relay mode, Bridge mode, AP mode, and Routing mode (which includes PPPoE dial-up, Static IP, and Dynamic IP).

3.2. Bridge Mode Settings:

Bridge mode settings can be found and configured in 'Advanced Mode'.

3.3. AP Mode Setting:

To configure AP mode, navigate to the software management page and select 'AP mode'. For easier management, the IP address and default gateway should be set within the IP network segment of the upper-level router, ensuring no IP conflicts. After setup, connect the WAN port to the external network. The management device can be accessed via the set IP address.

Note:

• When accessing the external network in AP mode, the IP address network segment for devices connected wirelessly to the AP is allocated by the upper-level device.
• By default, specific intranet IP addresses may not need to be set. However, if device management is required, manually set the IP address of the computer's local connection network card.

3.4. AP Mode WiFi Configuration:

In AP mode, you can set the 2.4G/5.8G wireless SSID name and password. After configuration, connect the WAN port to the external network. Other mobile devices can connect to the Internet by wirelessly connecting to the device's SSID and entering the password.

(The interface shows options for AP, Router, and Repeater modes. For AP mode, it displays network connection status and allows configuration of 2.4G/5.8G SSID and password, encryption (NONE), and a 'combine wifi' option, which is OFF by default.)

3.5. Routing Mode Setting:

In Routing mode, select the desired Internet access mode: 'PPPoE', 'Static IP', or 'Dynamic IP'.

• PPPoE Dial-up: Requires Internet account and password from the service provider. 2.4G/5.8G wireless SSID and password can be set.
• Static IP: Requires IP address, subnet mask, gateway, and primary DNS from the service provider. 2.4G/5.8G wireless SSID and password can be set.
• Dynamic IP: The WAN port accesses the Internet by obtaining an IP from the upper-level network device. 2.4G/5.8G wireless SSID can be set.

3.6. IPv6 Setting:

Supports DHCPV6 client, static IP, and Relay function. DHCPV6 client is enabled by default.

(The interface shows Router mode selected. WAN settings include WAN Type (DHCP Client), IPv6 (Disabled). Wireless settings for 5.8G and 2.4G SSID, encryption, mode, and PSK are available. A 'Combine WiFi' option is present.)

4. IPv6 Setting

Click the settings icon ⚙️ and select to enter the IPv6 setting page. IPv6 Status displays information about the obtained IPv6 address. IPv6 Setting allows configuration of LAN and WAN information.

(Screenshots show IPv6 Status with example IP addresses and gateway, and IPv6 Setting with options for WAN Type (DHCPv6 Client), DNS Acquisition Method (Auto), and LAN settings including prefix and addresses.)

5. Mesh Setting

Precautions:

• The Mesh controller node must be enabled in Router or AP mode (Router mode recommended).
• A Mesh network consists of a management node and at least one agent node.
• After enabling Mesh, click 'Trigger EasyMesh' on both nodes to pair.
• Mesh pairing takes about 2 minutes. View Mesh status on the management node page afterward.
• If pairing fails, try again after clicking 'Restore EasyMesh to Default' on the Mesh settings page.

EasyMesh Configuration:

Click the Mesh icon ? and select to enter the Mesh setting page. EasyMesh status shows the schematic diagram of a formed Mesh network, illustrating Controller, Agent, and connected mobile devices.

1. Select the role of Mesh (Controller or Agent).
2. If 'Controller' is chosen, set the Mesh SSID and password.

Click 'Settings' to save and enable the Mesh function.

(Screenshots show EasyMesh Status and EasyMesh Setting pages. The setting page allows enabling EasyMesh, selecting a Role (Controller/Agent), setting 5.8G/2.4G SSIDs and encryption (e.g., WPA2/WPA3), PSK, and includes options to 'Restore easymesh to default' and 'Trigger easymesh'.)

6. Light Control Status

Lights can be turned off in advanced settings, except for the power light.

7. FAQ

Q: What's the role of WiFi extender?

A: Boosts the range of your existing WiFi and creates a stronger signal in hard-to-reach areas. Note: It cannot increase your router's WiFi speed; the extending WiFi speed may be reduced.

Q: Where shall I place the WiFi extender?

A: Place the WiFi extender halfway between your router and the weak signal area, ensuring it is within the range of your existing WiFi router network.

Q: How to reset the WiFi extender?

A: Press the WPS/Reset button for 10 seconds. Wait for the indicator lights to turn off and then light up again to confirm factory settings have been restored.

Q: Why does WiFi keep disconnecting?

A: Resetting the WiFi extender is recommended.
