4. Operating Modes
The GEYILO WiFi Extender supports multiple operating modes to suit various networking needs:
4.1 Repeater Mode
In Repeater Mode, the extender wirelessly connects to your existing Wi-Fi router and amplifies its signal, extending coverage to areas with weak or no signal. This is the most common mode for home users.

4.2 Access Point (AP) Mode
In AP Mode, the extender connects to your wired network (via Ethernet cable) and transforms it 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.
4.3 Router Mode
In Router Mode, the extender functions 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.

- Keep Ventilated: Ensure the extender's ventilation holes are not blocked to prevent overheating.
- Regular Cleaning: Gently clean the device with a soft, dry cloth to remove dust. Avoid using liquid cleaners.
- Firmware Updates: Check the manufacturer's website periodically for firmware updates. Updating the firmware can improve performance, add new features, and enhance security.

- If using the Web Management Page, ensure your device is connected to the extender's default network before configuration.
- No Internet Access After Connecting to Extender:
- Check if your main router has internet access.
- Ensure the extender is successfully connected to your main router (check the signal indicator lights).
- Try repositioning the extender closer to your main router.
- Perform a factory reset on the extender (press and hold the WPS/Reset button for 7-8 seconds) and reconfigure it.
- Slow Speed on Extended Network:
- Relocate the extender to a position with a stronger signal from your main router.
- Minimize physical obstructions (walls, large furniture) between the extender and your devices.
- Ensure your devices are connecting to the appropriate band (5GHz for higher speeds, 2.4GHz for better range).
