The TV Wi-Fi signal drops or intermittently disconnects.

    If the Wi‑Fi signal occasionally or frequently disconnects or automatically disabled, first check and ensure the TV software is updated to latest version, then check the network icon or network notation status on the TV menu screen. After checking, choose your TV and try the following:

    IMPORTANT: If the TV cannot connect to Wi-Fi at all, refer to the article The BRAVIA TV cannot be connected to the Internet: how to perform a network diagnosis.

    1. Check your TV software is updated to latest version and the network icon or network notation status 

    Note:

    Select your TV type to check network icon or network notation status:

    Target Android TV models: A8H, A9S, X9000H, X80H, X81H, X85H, X90H, X91H (49, 85), X95H (55, 65, 75), Z8H, Z9H series

    2. Confirmation items

    1. The Wi-Fi signal strength is weak: If the signal is weak, signal drops might be reduced by placing the Wi-Fi router close to the TV.

    2. The TV is too close to the router: If the TV and router are too close, communication may not work. We recommend that you keep the distance between the TV and router at more than 1 meter.

    3. Other Wi-Fi devices are used in the same network: If other devices download large-sized files such as videos, the network speed might slow down. In this case, we recommend that you stop downloading videos.

    4. Reset the TV, router, and modem: By resetting these devices, the Wi-Fi signal connectivity might be improved.

    5. Interference from other wireless devices, electric equipment, or the environment: If many wireless devices or electric equipment such as microwaves are used at home, the Wi-Fi performance of the TV may be affected. Try to turn off these wireless/electric devices, or keep them away from the TV. Electromagnetic interference may also occur depending on the environment in which the TV is installed. If you can change the environment, change the installation location and check if the performance improves.

      • Devices that may cause electromagnetic interference
        • Microwave ovens
        • Cordless phones
        • Bluetooth devices
        • Garage door openers
        • Wireless toys, etc.
      • Environments that may cause electromagnetic interference
        • Places that generate electromagnetic interference such as near large transmission lines
        • Places that generate static electricity
        • Places where the walls, desks, or doors have metal surfaces, etc.

    6. Frequency band setting of the Wi-Fi router: Depending on your Wi-Fi router, the 2.4GHz, 5GHz, or 6GHz frequencies may be available. If 5GHz or 6GHz frequency bands are available, we recommend using one of those frequencies. (The availability of 6GHz depends on the country)
      Please check the TV specifications to see which frequencies are supported. For how to find the specifications, refer to the How can I find the specifications (dimensions, weight, connection terminals, wall mount, etc.) for the TV? article.

    7. Perform a Factory Data Reset* on your TV: Resolve temporary software issues that may affect the wireless connectivity.

    *Note that Factory Data Reset will deletes all customized settings, including channels, account information (such as a Google account), system and applications data, downloaded apps, wired and Wi-Fi network settings, parental lock settings, and camera device's data. The TV will return to how it was at the time of purchase.

    If you continue to experience network issues after following all of the steps above, we recommend using a wired LAN connection from your modem or router or contact us for further assistance.
