4.1 Početno smještaj
For initial setup, place the Wi-Fi Extender near your AT&T gateway (router). Once paired, you can move it to a more central location in your home where Wi-Fi signal is weak.
4.2 Priključak za napajanje

- Ensure the Power On/Off Switch (6) is in the 'On' position. The Power Indicator (3) should light up.
4.3 Pairing with Your AT&T Gateway (Router)
There are two primary methods for pairing:
Method A: Using WPS (Wi-Fi Protected Setup) - Recommended
- Pritisnite i držite WPS Button (4) on the front of the Wi-Fi Extender for 2-3 seconds until the indicator lights start blinking.
- U roku od dvije minute pritisnite Gumb WPS on your AT&T gateway (router). Refer to your gateway's manual for the exact location of its WPS button.
- Wait for the indicator lights on the extender (1, 2, and 3) to turn solid green, indicating a successful connection. This may take a few minutes as the extender updates its firmware and synchronizes with your gateway.
Method B: Using an Ethernet Cable (If WPS fails or is not preferred)
- Connect one end of an Ethernet cable (not included) to one of the Gigabit Ethernet Ports (5) on the back of the extender.
- Connect the other end of the Ethernet cable to an available LAN port on your AT&T gateway (router).
- The extender will automatically detect the connection and begin pairing. Wait for the indicator lights (1, 2, and 3) to turn solid green.
- Once paired, you can disconnect the Ethernet cable if you wish to use the extender wirelessly.
4.4 Optimalno postavljanje
After successful pairing, unplug the extender and move it to a location roughly halfway between your AT&T gateway and the area where you need improved Wi-Fi coverage. Ensure the extender is placed in an open area, away from large metal objects, concrete walls, or other electronic devices that might cause interference. Plug it back into a power outlet. The indicator lights should turn solid green again, confirming a good connection.
