Symptoms
- TV shows 'unable to connect' or 'no internet'
- Wi-Fi network doesn't appear in the TV's list
- TV connects but apps say there's no internet
- Connection worked before and stopped after a router change
Likely causes
- CommonWrong Wi-Fi password entered on the TV's on-screen keyboardOn-screen keyboards make typos in passwords easy to miss.
- CommonRouter or modem needs a restartClears many temporary connectivity issues.
- CommonTV only supports 2.4GHz and network is 5GHz-onlyOlder smart TVs often lack 5GHz Wi-Fi support.
- PossibleRouter changed name or password recentlyA new router or ISP-provided equipment resets network credentials.
- Less commonTV's Wi-Fi antenna or software issuePersistent failures across multiple networks can indicate a hardware fault.
What to do
- Restart the router and modem by unplugging both for 30 seconds.
- Restart the TV using its power button or by unplugging it for a minute.
- Carefully re-enter the Wi-Fi password, double-checking capitalization and special characters.
- Confirm the network name you're selecting is 2.4GHz if the TV doesn't list a 5GHz option.
- Move the TV closer to the router temporarily to rule out signal strength.
- Check for a TV software update in the settings menu, since Wi-Fi bugs are sometimes fixed this way.
- If the TV connects to Wi-Fi but apps still show no internet, check the router's DNS settings or try resetting network settings on the TV.
When to call a pro
If no other device can connect to that network either, the issue is the router or ISP, not the TV.
