To fix no network detected on a Vizio TV, reconnect to your Wi-Fi network with the correct password, then restart the TV and router if the connection still fails. Run the TV’s connection test to decide whether to troubleshoot the network or refresh Vizio Home. Save a factory reset for after the connection checks, since it erases your Wi-Fi credentials, accounts, and customized settings.
The short version
- Reconnect first: Select your home Wi-Fi in Network settings and enter its case-sensitive password.
- Restart both ends: Power-cycle the TV, then restart your modem and router if reconnecting does not work.
- Isolate the cause: Test another device on your home Wi-Fi and try a hotspot or Ethernet connection if your TV has an Ethernet port.
- Follow the test result: A successful connection test points you toward Home-screen troubleshooting if Home still fails.
- Reset last: A factory reset removes Wi-Fi credentials, accounts, and customized settings.

Reconnect your wireless network and test internet access
Press Menu or the Gear button on your remote, open All Settings, then select Network. Choose your home Wi-Fi network, enter its password, and select Connect. On a TV without All Settings, open Network directly from the menu.
Check capitalization, spaces, and symbols when entering the password, because your wireless password is case-sensitive. You can find it on the router or modem label, in your internet provider’s app, or on a device already connected to that Wi-Fi. Your Vizio account password is a different credential.
For a saved connection that keeps failing, select the network in Network settings and choose Forget Network if available. Select the network again, enter its password, and choose Connect. Some models label the removal control Forget.
Next, open All Settings > Network > Test Connection. A result of 0 or Unavailable means you should continue with the network fixes, starting with a restart. If the connection test succeeds but Home will not load, try the Home refresh below.
Refresh Vizio Home when internet works
If Vizio Home or SmartCast remains unavailable despite a successful connection test, open All Settings > System > Menu Language. Select Spanish or French and keep the settings menu open while Home loads. After it loads, return to Menu Language and select English.
Vizio recommends this language change for an unavailable Home screen when the internet connection works. If Home still fails, restart the TV using one of the options below.
Restart the TV and your network equipment
Unplug the TV from power for at least five seconds. While it is unplugged, hold its physical Power button for five seconds on models with that button. Reconnect the power, turn on the TV, and retry the Wi-Fi connection through Network.
You can also restart through All Settings > Admin & Privacy > Restart TV, then select Yes. Some models use Soft Power Cycle in that location instead. Select the option your TV displays and follow its confirmation prompts.
Other supported menu layouts use System > Reset & Admin > Soft Power Cycle or System > Reboot TV. A V-Series variant places Reboot TV under Admin & Privacy. Follow the prompts and allow the TV to restart.
Test internet access on a phone or another device connected to the same home Wi-Fi. If that device also fails, disconnect your modem and router from power for at least 10 seconds. When they are separate devices, reconnect the modem first, then the router, and wait for the network to restart before reconnecting the TV.
If internet access does not return on the other device, contact your internet provider. When other devices work but the TV still fails, continue with reception and DHCP checks.
Improve reception and refresh DHCP
Move the router into an open, central position, or move the TV nearer to it. Keep the router away from cabinets, large furniture, metal objects, microwaves, cordless phones, and baby monitors. For reception problems elsewhere in your home, follow the steps to fix a weak Wi-Fi signal.
When your router broadcasts separate network names for its bands, select the 2.4 GHz network in the TV’s Network settings and enter its password. Vizio recommends trying this band for weak reception or connection trouble. Your TV may support other bands too.
On models with manual network controls, open All Settings > Network > Manual Setup > DHCP. Turn DHCP on if it is disabled; otherwise, turn it off and back on. Retry the connection and run Test Connection again before moving to another network.
Try a hotspot or Ethernet connection
A different network helps you isolate a problem with your home router. Enable your phone’s hotspot, confirm that cellular data works, and check the hotspot name and password. Keep the phone near the TV, select its hotspot in the TV’s Network settings, and enter the password.
For an iPhone 12 or later, open Settings > Personal Hotspot and turn on Allow Others to Join. Enable Maximize Compatibility and keep that screen open while connecting the TV. Restart both devices if necessary, though a hotspot connection is not guaranteed to work.
If your TV has a built-in Ethernet port, connect a cable between it and your router, then run Network > Test Connection. Some newer Vizio models have no Ethernet port, so check the TV before choosing this route. If a wired connection fails, reseat the cable at both ends and test it with another wired device or substitute a working cable.
If the TV works on a hotspot but fails on home Wi-Fi, that result points toward a home-network problem. Check your router’s restrictions and compatibility settings next. If another Ethernet cable also fails, investigate the router or internet service, and keep your connection-test results for Vizio support.
Check router restrictions and compatibility
If your router shows the TV as paused or blocked, restore its access using the router’s controls. On eero, open the TV under Home > Devices or the Devices tab, then select Resume device. If its whole profile is paused, open that profile from Home and select Resume profile.
For a blocked eero device, open Devices > Blocked, select the TV, open the more-options control, and choose Unblock device. You need access to the network’s controls to make these changes.
If encryption compatibility prevents your TV from connecting to eero, open Settings > Network settings > Encryption. Try Standard (WPA2) for the TV’s 2.4 or 5 GHz band when Hybrid or Enhanced prevents connection. The 6 GHz band requires WPA3, so this WPA2 option does not apply to it.
To try 2.4 GHz on an eero network with a shared network name, open Settings > Troubleshooting > My device won’t connect > My device is 2.4 GHz only. Select Pause 5 GHz and 6 GHz, then connect the TV during the 10-minute window. The other bands return automatically.
If compatibility trouble persists, contact eero Support and request Compatibility Mode. Support can disable WPA3, Client Steering, and DFS together for devices that cannot connect. These router changes address specific compatibility problems and do not guarantee a fix for every Vizio connection failure.
Update the TV before resetting it
Once Ethernet or an alternate Wi-Fi network provides working internet, open All Settings > Admin & Privacy > Check for Updates and select Yes. Supported older models use System > Check for Updates. Install an available update, then retry your usual connection.
For model-specific firmware information, open Vizio’s Find Your Firmware page, enter the TV’s serial number, and select Get Firmware Data. Follow the instructions for your exact model. Use USB installation only when Vizio provides that option for your model.
Factory reset and get help if the connection still fails
Use a factory reset after reconnecting, restarting, and testing another connection have failed. It erases your Wi-Fi credentials, accounts, and customized settings, so you will need to complete setup again. Have your wireless password ready before proceeding.
Press Menu and open All Settings > Admin & Privacy > Reset to Factory Settings. Other documented layouts place Reset to Factory Settings directly under Admin & Privacy or under System > Admin & Privacy. Some models label the option Reset TV to Factory Settings or Reset to Factory Defaults. Enter your PIN when prompted; the default is 0000 unless you changed it.
Select Reset or Reset TV, press OK, and complete the TV’s setup again. Choose your home network and enter its password during setup, then repeat the connection test. If the TV still cannot detect networks or connect, contact Vizio with its model, serial number, and the results from your home-network, hotspot, or Ethernet tests.
On Vizio’s Contact Us page, select Chat is Available for chat assistance or Send a Text for text support. To request a callback, complete Vizio’s Customer Support Callback Request form and select Submit.
You can also open Vizio’s Self Service Request portal, select Next, and follow the product-registration and troubleshooting prompts. If troubleshooting fails and your TV meets the warranty criteria, the portal can arrange a warranty service order.
Frequently Asked Questions
Can Vizio Mobile reconnect a completely offline TV?
Vizio Mobile normally requires your phone and TV to be connected to the same Wi-Fi, so it cannot generally establish the first connection for a completely offline TV. For a compatible TV already on the network, sign in to the app, select the TV, and enter its four-digit pairing code to use the remote controls.
What should you do if your TV’s menus differ from these paths?
Use Vizio’s Find Your User Manual lookup to get instructions for your model. Enter it in Enter Model Number, select the matching result, and open User Manual. Allow pop-ups if the manual does not open.
Can a Vizio TV connect to a guest network with a sign-in screen?
Supported models and guest networks offer a QR-code sign-in flow. Open All Settings > Network > Wireless Access Points, select the guest network, and scan the displayed QR code to follow its instructions. Availability depends on your TV’s software and the guest network.
Do all Vizio TVs install updates automatically while turned off?
Vizio documents that behavior for the D24h-G9, D32h-G9, and D40f-G9. On those models, your initial internet connection triggers updating, and later updates download and install automatically while the display is powered off. Check your model’s instructions before expecting the same timing on another TV.
Should you reinstall a streaming app when only that app fails?
App removal and reinstallation is not a supported general SmartCast repair. For PBS, open Settings > Change Account in the app, follow Sign In, and use the displayed code to complete activation and sign in again. Use this account repair when your TV’s internet works but PBS alone fails.
