5.2. Web Browser Method (Manual Setup)
- Plug the WiFi Extender into a power outlet.
- On your computer or smartphone, connect 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 (usually 192.168.1.1 or 192.168.0.1) or the setup URL provided in the Quick Installation Guide.
- Follow the on-screen instructions to select your existing Wi-Fi network and enter its password.

6. Operating Instructions
The NEWFAST N300 WiFi Extender supports two main operating modes: Repeater Mode and AP Mode.
6.1. Repeater Mode
This is the default mode, used to extend the coverage of an existing wireless network. The extender connects wirelessly to your main router and rebroadcasts the signal, expanding its range.
6.2. AP (Access Point) Mode
In AP Mode, the extender converts a wired internet connection into a wireless network. This is useful if you have an Ethernet port with internet access but need to create a Wi-Fi hotspot.
6.3. Device Compatibility
The extender is compatible with any wireless network devices that comply with the 802.11b/g/n standard. This includes most routers, modems, smartphones, tablets, laptops, and smart TVs.

If you encounter issues with your NEWFAST N300 WiFi Extender, refer to the following common problems and solutions:
