It is guaranteed to be compatible and supports standards. 802.11b/g/n on frequency 2.4 GHzAn alternative is chip-based adapters. Ralink RT5370 (For example, TP-Link TL-WN725N ver.1), but their work is not always stable.

Step-by-step instructions:

Turn on your TV and wait until it loads completely.

Plug the adapter into the port USB on the back panel (it is better to use the top connector)

Make sure your router is turned on and broadcasting a 2.4 GHz network.

Write down your Wi-Fi network name and password.

-->

1. Press on the remote control HOME → Settings → Net → Network setup.
2. Select Wireless setup (If the item is missing, update the firmware or check the adapter compatibility).
3. Find your Wi-Fi network in the list of networks. If there's no network:
   • 🔄 Reboot your router.
   • 📶 Check that the network is working in mode 802.11n (and not 802.11ac).
   • 🔌 Try a different USB port on your TV.

Wait for the message "Connected to the Internet". Check the connection by running YouTube or Netflix.

Critical feature: The UWA-BR100 adapter only supports the 2.4 GHz band. If your router only supports 5 GHz, you won't be able to connect. In this case, configure the router to dual mode (2.4 and 5 GHz simultaneously) or use a cable connection.

3. Method 2: Wired connection (LAN)

The most stable method is connecting via cable EthernetIt does not require additional adapters and provides maximum speed (up to 100 Mbps For KDL-40WD653). This method is required if:

• 🚫 The TV does not support Wi-Fi (basic version).
• 📡 The router is far away and the Wi-Fi signal is weak.
• 🎮 Are you planning to play online games or watch videos in 4K (although the model only supports Full HD).

5. Wait for the message "Connected to the Internet".

If after connecting the cable the TV writes "No internet connection", check:

• 🔌 Is the cable inserted correctly (it should click).
• 🔄 Restart your router and TV.
• 🛠️ Is the server enabled on the router? DHCP (usually enabled by default).

4. Method 3: Alternative methods of connecting to Wi-Fi

If purchasing an adapter or installing a cable is not possible, consider these workarounds:

4.1 Using Powerline Adapters

Technology Powerline transmits the internet signal through electrical wiring. This requires two adapters (for example, TP-Link AV600):

1. Connect one adapter to the router via LAN and plug it into the socket next to it.
2. Plug the second adapter into the socket next to the TV and connect it with a cable. Ethernet.

The speed will be lower than via cable, but more stable than via Wi-Fi.

4.2. Bridge mode on the second router

If you have a second router, you can configure it in mode bridge (WDS):

1. Connect the second router to the main one via LAN.
2. In the settings of the second router, activate the mode WDS or Repeater.
3. Connect your TV to the second router via cable or (if supported by the model) via Wi-Fi.

What should I do if my TV doesn't detect the Powerline adapter?

Check that both adapters are connected to the same electrical network (not through a residual current device or different phases). Try reconnecting them to different outlets without filters or extension cords. If the adapters are new, update their firmware using the manufacturer's utility.

4.3. Mobile hotspot (temporary solution)

As a last resort, you can share the Internet from your smartphone:
