5. Funcionament de l'extensor d'abast
Once set up, the RE505X operates to extend your Wi-Fi coverage. Here are key operational aspects:
5.1. Extended Network Connection
Your devices can connect to the extended network using the same Wi-Fi name (SSID) as your main router if OneMesh is enabled, or a new SSID if configured manually. The extender will automatically choose the best band (2.4 GHz or 5 GHz) for your devices.

5.2. OneMesh Functionality
If your main router supports TP-Link OneMesh, the RE505X can join the Mesh network. This creates a unified network with a single Wi-Fi name, allowing your devices to seamlessly roam between the router and extender without disconnections. To enable OneMesh, ensure your TP-Link router's firmware is updated to the OneMesh version.
5.3. Access Point (AP) Mode
The RE505X can also function as a wireless access point. Connect an Ethernet cable from your router (or any wired network source) to the Gigabit Ethernet port on the RE505X. The extender will then broadcast a new dual-band Wi-Fi network, converting your wired connection into a high-speed wireless signal.

5.4. Gigabit Ethernet Port Usage
The Gigabit Ethernet port can be used to provide a stable wired connection to a device such as a desktop computer, smart TV, or game console, even when the extender is operating wirelessly.
6. Manteniment
To ensure optimal performance and longevity of your RE505X, consider the following maintenance tips:
- Actualitzacions de firmware: Comproveu i instal·leu regularment si hi ha actualitzacions de firmware a través de l'aplicació Tether o del web interfície de gestió. Les actualitzacions sovint inclouen millores de rendiment, pegats de seguretat i noves funcions.
- Col·locació òptima: Periodically re-evaluate the extender's placement using the Intelligent Signal Light to ensure it maintains a strong connection to your router, especially if your network layout changes.
- Neteja: Mantingueu el dispositiu net i lliure de pols. Feu servir un drap suau i sec per netejar l'exterior. Eviteu utilitzar netejadors líquids o materials abrasius.
- Ventilació: Ensure the extender's ventilation slots are not obstructed to prevent overheating.
- Reinicia: If you experience intermittent issues, try restarting the extender by unplugging it from the power outlet for 10 seconds and then plugging it back in.
7. Solució De Problemes
If you encounter issues with your RE505X, refer to the following common troubleshooting steps:
7.1. No Internet Access After Setup
- Check Signal Light: Ensure the Intelligent Signal Light on the extender is solid blue. If it's red or off, the connection to your router is weak or non-existent. Relocate the extender closer to your router.
- Verifica la connexió del router: Ensure your main router is working correctly and providing internet access.
- Re-configure: Try re-configuring the extender using the Tether app or web interfície.
7.2. Frequent Disconnections or Unstable Connection
- Col·locació òptima: The most common cause of instability is poor placement. Ensure the extender is positioned where the Intelligent Signal Light is solid blue. Avoid placing it near large metal objects, concrete walls, or other electronic devices that may cause interference.
- Interferència: Other wireless devices (cordless phones, microwaves, Bluetooth devices) can cause interference. Try changing the Wi-Fi channel on your main router.
- Actualització del firmware: Ensure the extender's firmware is up to date.
- Problemes amb l'encaminador: Check if your main router is experiencing issues.
7.3. Ho vaig oblidar Web Contrasenya de gestió
Si oblideu la contrasenya per a web management interface, you will need to reset the extender to factory default settings. Locate the Reset button (usually a small pinhole) on the extender, press and hold it for about 5-10 seconds until the LEDs flash, then release. The extender will restart with default settings, and you can set up a new password during the re-configuration process.
7.4. Slow Speeds on Extended Network
- Col·locació: Ensure the extender is placed optimally. While extending range, some speed reduction is normal, but poor placement can severely impact it.
- Selecció de la banda: For high-bandwidth activities, ensure your devices are connecting to the 5 GHz band if possible.
- Congestió de la xarxa: Too many devices on the network or heavy internet usage can slow down speeds.
