TV cannot connect to Wi-Fi at all

• Network name is missing: check whether the router broadcasts a compatible band and whether the TV sees other networks.
• Network appears, but the password is rejected: verify the exact password and its capitalization before changing router security.
• TV says connected to Wi-Fi but has no internet: use the separate connected-without-internet checks; joining Wi-Fi is not the same as reaching the internet.
• TV cannot finish joining or shows a network error: use the TV’s connection test and compare it with another device on the same network.

Write down the exact message rather than paraphrasing it. Samsung’s support flow separates an unseen network from password failure and from later network-status errors; LG likewise recommends checking another device and the TV’s connection state. The menu labels below are examples only for the named brands.

1. Check whether another device can see the home network in the same room as the TV.

   If no device sees it, investigate the router or whether its Wi-Fi radio is on. If the TV alone cannot see it, check model band support, signal and whether the network is hidden.

   If that does not help: If the TV sees no networks at all after a restart, contact the manufacturer with the model and result rather than assuming the router is the cause.

2. If you intentionally hide the router’s network name, use the TV maker’s documented manual-add option or temporarily make the name visible for troubleshooting.

   The TV can attempt to join a known network even if it does not appear in a scan, on models that support manual entry.

   If that does not help: Restore the router’s original visibility setting after the test and ask the router maker if you are unsure how.

3. Check the TV manual for supported Wi-Fi bands and router requirements.

   A network that uses an unsupported band or configuration may not appear even when it works for phones and computers.

   If that does not help: Do not infer that all models of a brand share the same wireless limits; provide the exact model code to support.

1. Use the TV’s show-password option if available and re-enter the password carefully, including upper/lowercase letters and punctuation.

   The TV should accept the same credentials used by another device on that exact network.

   If that does not help: If the password is long or complex, verify it from the router label or administrator; do not change the router password just to make TV typing easier.

2. Confirm that you selected the intended network name, especially if the router has guest and main networks with similar names.

   The TV will be joining the network whose password you entered.

   If that does not help: If credentials are correct but rejected, note the exact TV error and check the router’s supported security settings with its maker or ISP.

Check whether other devices remain online and whether the router recently changed. Samsung advises checking whether network settings were altered when the TV stopped connecting; LG’s guidance also distinguishes a TV-only problem from router or provider trouble. If the router was recently replaced or its security/access controls changed, give that timing to the person who manages it.

1. Restart the TV using its normal power menu, then try once more and run the network status test if offered.

   The test may show whether the TV failed to join the router or joined but cannot reach the internet.

   If that does not help: Record the status screen or message and move to a targeted network reset only if the TV maker documents one for your model.

2. If the TV offers a forget-network or reset-network command, remove only the saved network and reconnect using the confirmed password.

   This refreshes the TV’s saved connection without erasing the full TV setup.

   If that does not help: If the TV still fails while other devices work, ask the TV manufacturer. If several devices fail, ask the ISP or router maker.

A TV that cannot see a network needs a different check from a TV that sees it but rejects credentials. DNS settings apply after the TV has joined a network; changing DNS does not make an unsupported Wi-Fi band appear or correct a mistyped password. A factory reset is broader still and can remove apps and accounts. Start with the stage-specific checks above, then escalate with the exact model and error.

Why does my TV see Wi-Fi but say it cannot connect?

The password may be incorrect, the TV may not support the router’s settings, or a router access/security rule may block it. The error message and comparison with another device help separate those causes.

Can I use a phone hotspot to test the TV?

If the TV and phone support it, a temporary hotspot can show whether the TV can join a different network. It does not prove the home router is faulty or rule out every TV issue; it is one comparison test.

Should I reset the TV if Wi-Fi will not connect?

Try the exact failure-stage checks and the manufacturer’s network reset first. A factory reset erases more and should be reserved for a model-specific recommendation.
