Fix Wi-Fi connection problems on your Vizio Smart TV.

## Fix in order

<Steps>
  <Step title="Check your router">
    Test another device on the same Wi-Fi. If nothing connects, the issue is your router or ISP.
  </Step>

  <Step title="Restart router and modem">
    Unplug both for 60 seconds. Plug the modem in first, wait 30 seconds, then plug in the router.
  </Step>

  <Step title="Forget and re-add the network">
    **Menu > Network > Network Connection**, select your network, choose **Forget**, then reconnect and re-enter the password.
  </Step>

  <Step title="Verify the password">
    Passwords are case-sensitive. Confirm by logging into your router at `192.168.1.1` or checking the sticker.
  </Step>

  <Step title="Try the 2.4GHz band">
    Some Vizio TVs don't support 5GHz. Connect to your 2.4GHz network for better range.
  </Step>

  <Step title="Test signal strength">
    Move the TV closer to the router. If it connects, use a Wi-Fi extender or Ethernet.
  </Step>

  <Step title="Update firmware">
    **Menu > System > Check for Updates**.
  </Step>

  <Step title="Reset network settings">
    **Menu > Network > Manual Setup > Reset Network**, or factory reset as a last resort (PIN: `0000`).
  </Step>
</Steps>

## Alternative: use Ethernet

Plug an Ethernet cable into the TV's **LAN** port and your router. Go to **Menu > Network > Network Connection > Wired**. This bypasses all Wi-Fi issues.

## Troubleshooting

<AccordionGroup>
  <Accordion title="Connects but keeps disconnecting">
    Check signal strength. Reserve a static IP for your TV in your router settings.
  </Accordion>

  <Accordion title="Wi-Fi not found in list">
    Verify the network is broadcasting. For hidden SSIDs, use **Enter Network Manually**.
  </Accordion>

  <Accordion title="'Incorrect password' error with correct password">
    Router may have MAC filtering enabled, or is set to WPA3-only. Try WPA2/WPA3 mixed mode.
  </Accordion>

  <Accordion title="Connected but no internet">
    Set manual DNS to `8.8.8.8` and `8.8.4.4` in **Menu > Network > Manual Setup**.
