IMPORTANT: This article applies only to specific products and/or operating systems. Check Applicable Products and Categories for details.

1. Make sure the TV has the latest system software update installed. Downloads are posted on your model support page.
2. Make sure the UWA-BR100 wireless LAN adapter (required) is connected securely to the USB port on the TV.
   • The use of other USB adapters is not supported.
3. Check the wireless connection using a different device.
   • If a different device doesn't connect to the internet, make sure the modem and router are on.
4. Check or change your router settings. Refer to the router documentation to perform these instructions.
   • If the router uses multiple frequencies, try a different frequency.
     • Some TVs can't connect to a 5 GHz connection. Check your TV manual for more details. Manuals are posted on your model support page.
     • Make sure your TV isn't placed near other devices that use the same frequency. Devices such as cordless phones, baby monitors, microwaves, and other Bluetooth® devices may cause interference.
   • Change the channel of your router to see if the signal strength improves.
   • For DSL customers, the router setup might require a user name and password and the router will be set to PPoE. Internet-capable Tvs support broadband internet connections only. They are not compatible with dial-up.
5. Perform a power reset on the router.
   1. Unplug the power cord from the electrical outlet for one minute.
   2. Plug the power cord back in and wait until the router lights indicate that it has completely restarted (the lights stop flashing and remain lit).
   3. If the issue still occurs, there may be a problem with the router or with your Internet Service Provider. Contact the router manufacturer or ISP for further assistance.
6. Check the Network Status.

   1. Using the supplied TV remote control, press the HOME button.
   2. Select Settings.
   3. Select Network Setup.
   4. Select View Network Setup.
   5. Press ENTER to confirm the network status.
      • Wireless Device should be OK. This means that the TV is connected to the UWA-BR100 wireless LAN adapter. If it isn't:
        1. Make sure that the Network SSID of the router is visible.
           • If the signal strength of the connection to your router should be present. If it appears as a dash (-), the TV isn't connected to the router.
           • If the signal strength is weak, try the following:
             1. Move the router closer to the TV. Try to keep it more than 1 meter (3 feet) from the TV.
             2. Turn off or disable any other devices on the network. this includes gaming devices, computers, and internet phones.
        2. Connect a different USB storage device to the USB port on the TV to make sure the USB port is working.
           • If the other USB device doesn't work, the TV may require repair.  Go to Product Repair. 
      • Local Access and Internet Access should be OK. This means that the TV sees the Sony internet server.
        • If either failed, make sure the security key is entered correctly. The secuirty key or passphrase is case sensitive. Contact your ISP for further assistance.
        • Make sure the IP address is visible. If the IP adress flashes or starts with 169, manually set the IP address to the TV.

7. If the issue still occurs, reset the TV to factory settings.
