You may need to adjust the router’s antennas or move the router closer to the Vizio smart TVs to improve the signal.

Check if there are any available software or firmware updates for your Wi-Fi router and install them.

Updates often contain important security patches and connectivity fixes which could help establish a stable network connection with your Vizio TVs.

Once you’ve confirmed your WiFi network is functioning well and providing a strong signal, you can move on to troubleshooting potential issues with your Vizio TV’s connectivity settings and features to resolve the Vizio TV ” no network detected” error.

With some patience and systematic troubleshooting, you’ll get your Vizio TV back online in no time.

Check if your Vizio TV WiFi adapter needs an update

  • To ensure your Vizio TV can connect to the internet properly, you should check if the WiFi adapter requires an update.
  • To begin, hit the menu button on your Vizio TV remote. Select system, followed by system information.
  • Locate the WiFi Mac address and WiFi driver version. Write these down or take a photo with your phone for reference.
  • On a laptop or mobile device, visit Vizio’s support website at Select your specific Vizio TV model.

  • Download the update to a USB flash drive.
  • With your TV on, plug the USB drive into the USB port on the side or back of the TV. The update should start automatically within 30 seconds.
  • Follow the on-screen prompts to complete the installation. This typically takes 2 to 5 minutes. Do not unplug the TV or remove the USB drive during the update.

Once the update is installed, your Vizio TV will automatically reboot. After it powers back on, try detecting WiFi networks again.

If you continue to have issues connecting, there may be a problem with your router or modem.

Contact your internet service provider for further help.

Reset TV network settings

A known bug in some Vizio TV models causes the time to reset after a reboot.

If your Vizio TV is connected to WiFi but not detecting a network, one of the first troubleshooting things to attempt is to reset the network settings.


Check your WiFi router’s functionality by connecting additional devices to the same WiFi network, such as your phone, tablet, or computer.

If they can connect to the internet, the problem is most likely with your Vizio TV’s network settings.

You’ll need to reset your TV network settings to default and start over with your WiFi connection.

Use your Vizio TV remote to navigate to the ‘settings’ menu. Select ‘network‘ or ‘ethernet’ depending on how your TV connects to the internet.

Choose ‘reset to default’ or ‘factory reset’ to erase your current network information.

  • Turn your Vizio TV and WiFi router off for at least 30 seconds. This clears their caches and resets their network hardware.
  • Power your WiFi router back on and wait 2 minutes for it to fully restart. Then turn on your Vizio TV.
  • Go through the initial setup process to connect your Vizio TV to your WiFi network. Carefully enter your network name (SSID) and password.
  • Load an app, stream video, or browse the web to see if your Vizio TV now has an internet connection.

Resetting your network settings is a simple first step, but can resolve many connectivity problems with your Vizio TV.

Be patient through the process and try power cycling additional components like your modem or streaming devices if issues continue.

Check if your router’s firewall is blocking the Vizio TV

If your Vizio TV is connected to WiFi but there is no network detected, the problem might be with the firewall settings on your router.

Firewalls are designed to block unauthorized access to your network, but they can sometimes interfere with devices like smart TVs.

Tweaking your router’s firewall settings might resolve the issue, allowing your Vizio TV to detect the network more easily and ensuring a network-detected connection for uninterrupted viewing.

Disable your router’s firewall temporarily

As a test, you can disable your router’s firewall to determine if it’s interfering with your Vizio TV’s network connectivity.

Temporarily disable any firewall, wireless security, or network protection features.

After disabling it, check if your Vizio TV can now detect your WiFi network.

Allow “multicast” and “SSDP” traffic

Many smart TVs use multicast DNS server and SSDP network management protocol to discover the network, and it’s often blocked by router firewalls.

Log into your router’s admin page and look for options related to “multicast,” “SSDP,” “DNS server,” “network services,” or “service discovery”.

Ensure any options to block or filter multicast DNS server, SSDP, or DNS server traffic are disabled.

Allowing this kind of traffic may fix Vizio TV issues detecting your WiFi network.

For WiFi-connected Vizio TVs with no network detected, changing the settings for your router’s firewall and network protection features is typically a good solution. 

Factory reset Vizio TV

A factory reset may help to repair the problem if your Vizio TV is connected to WiFi but there is no network detected.

This will erase all saved information and restore default settings, which can often fix software glitches preventing network connectivity.

Performing a factory reset of your Vizio TV

  • On your Vizio TV remote, look for the menu or settings button. This is usually a button with an image of a gear or toolbox. Press to open the menu.
  • Navigate to and select the option labeled “reset & admin” or “system” using the directional buttons on your remote.
  • Choose “factory reset” or “reset to factory defaults.” This option will erase all saved information and restore default settings.
  • Press “ok” or “Yes” to confirm the factory reset. The TV will then restart with default settings.
  • Once restarted, go through the initial setup steps like selecting a language and connecting to your WiFi network. Your Vizio TV should now be able to detect WiFi networks and connect to the internet.

If issues persist, double-check that your WiFi router firmware is up to date, the network password is correct, and your WiFi signal strength is strong near the TV.

If everything else fails, you might need to get in touch with Vizio TV support for more help troubleshooting network connectivity or any hardware problems stopping your Vizio TV from connecting to the internet.

A soft reset or hard reset may also resolve software glitches, but will not restore default settings.

Performing a reset on your Vizio TV is an effective way to troubleshoot network detection problems and restore connectivity.
