Why does only my TCL smart TV keep dropping Wi‑Fi?

Answer

Smart TVs often drop when a router’s Smart Connect / band-steering feature moves them between 2.4 and 5 GHz. Turn off Smart Connect or give the TV a stable 5 GHz or 2.4 GHz SSID of its own.

Follow these steps

  1. Open the router Wi‑Fi settings

    On a phone, open the TP-Link Tether app, or in a browser go to the router’s admin address (often on the label, such as tplinkwifi.net), and sign in.

    You should see: You reach Wireless / Wi‑Fi settings.

  2. Turn off Smart Connect / band steering

    If you see Smart Connect or a single combined SSID option, turn it off so 2.4 GHz and 5 GHz use separate network names.

    You should see: Two distinct Wi‑Fi names are available.

  3. Reconnect the TCL TV to one band

    On the TV, forget the old Wi‑Fi network, then join either the 5 GHz or 2.4 GHz name and enter the password. Prefer 5 GHz if the TV is close to the router.

    You should see: The TV stays associated to one band.

  4. Test a long streaming session

    Play a streaming app for 20–30 minutes and watch whether the connection drops.

    You should see: The TV remains online without manual reconnects.

  5. Use Ethernet if Wi‑Fi still drops

    Connect an Ethernet cable from router to TV if a port is available, or move the TV closer / add a mesh node dedicated to the TV’s location.

    You should see: A wired or stronger wireless path stops the drops.

Extra tips

What to look for: TV-only disconnects, especially during streaming apps, while phones and other devices stay connected

Before you change anything: Have the router admin password ready (often on the router label). Note whether the router uses Smart Connect or a single combined SSID. Avoid factory-resetting the TV again until router wireless settings are checked.
