4. Opsætningsvejledning
Follow these steps to set up your AT&T Air 4920 Wi-Fi Extender:
4.1 Indledende placering
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 Strømtilslutning
- Connect the provided power adapter to the DC Power Input (7) on the back of the extender.
- Sæt strømadapteren i en stikkontakt.
- 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
- Tryk og hold på WPS Button (4) on the front of the Wi-Fi Extender for 2-3 seconds until the indicator lights start blinking.
- Inden to minutter skal du trykke på WPS knap 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 Optimal placering
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.

5. Operating Your Wi-Fi Extender
Once set up, the AT&T Air 4920 operates automatically to extend your Wi-Fi network. Your devices will seamlessly connect to the strongest signal, whether from your gateway or the extender, using your existing Wi-Fi network name (SSID) and password.
Status for indikatorlys:
- Solid grøn: Excellent connection and operation.
- Konstant rav/orange: Fair connection. Consider repositioning the extender closer to your gateway.
- Fast rød: No connection or poor signal. Reposition the extender or check connections.
- Blinker: During WPS pairing or firmware update.
- Slukket: Enheden er slukket eller modtager ikke strøm.
Kablede forbindelser:
You can connect wired devices (e.g., desktop computers, smart TVs, gaming consoles) to the Gigabit Ethernet Ports (5) on the back of the extender for a stable, high-speed connection.
6. Vedligeholdelse
To ensure optimal performance and longevity of your Wi-Fi Extender:
- Rensning: Gently wipe the exterior with a soft, dry cloth. Do not use liquid cleaners or aerosols.
- Ventilation: Ensure the ventilation slots are not blocked to prevent overheating.
- Firmwareopdateringer: The extender typically receives automatic firmware updates from AT&T. Ensure it remains connected to power and your network for these updates to occur.
- Power Cycle: If you experience minor issues, try unplugging the extender from the power outlet for 10 seconds and then plugging it back in.
7. Fejlfinding

| Indicator lights are red or amber. | Poor or no connection to the gateway. |
|
| Wi-Fi signal is still weak in extended areas. | Suboptimal placement. | Move the extender to a more central location between your gateway and the weak signal area. Avoid placing it in corners or behind furniture. |
| Devices not connecting to the extender. | Extender not properly paired or network issues. |
|
| Need to reset to factory settings. | Configuration issues or preparing for new setup. | With the extender powered on, use a paperclip or similar pointed object to press and hold the Nulstillingsknap (8) for about 10 seconds until the lights flash.
