5.3 Working Modes
Upon entering the setting page, you will find four primary working modes:
- AP Mode
- Bridge Mode
- Router Mode
- Repeater Mode
5.3.1 AP Mode Configuration
In AP mode, you will configure the IP Address and Subnet Mask. These settings should be within the same network segment as your upper network and must not conflict with the upper network router's IP address.
- Click on "AP Mode" in the wizard.
- Set the IP Address and Subnet Mask.
- Configure the 2.4G/5.8G wireless SSID, password, channel, and country.
- Click "Next" to save settings.
Note:
- In AP mode, IP addresses for other connected devices will be allocated by the upper network router.
- The AP requires an intranet IP address (do not use the same IP as the upper router). For device management, manually set your computer's IP address to the same network segment as the AP's intranet IP.
