Method 1: Power cycle the Vizio Smart TV
This is the easiest process to fix no network detected error on Vizio Smart TV, where you have to soft reset the device and clear the corrupted cache files. You can either use the power cycle menu on the TV or rely on power cycling on all the electronic devices.
You can use the Menu button to power cycle the Vizio Smart TV, but if your remote is unavailable then apply the next method.
Tap on the Menu button of the remote control, go to System > Reset and Admin and then click on Soft Power Cycle.
Otherwise, you can turn off the TV, unplug the cables from the power outlet, and press the Power button of the TV for at least 30 to 60 seconds. Next, plug in the cables and turn on the TV.
Method 2: Check the Wi-Fi network with other devices
You need to check whether the problem is associated with the TV or the Wi-Fi router due to which no network detected is appearing.
So, to verify, you can connect other devices to the network router, which includes gaming consoles, smart devices, and computers, and check whether the devices are able to connect to the Wi-Fi. You can also try to load a web page on the browser, if it works, then the issue is associated with the Vizio Smart TV, otherwise, you need to troubleshoot the router.
Method 3: Power cycle the router
Power cycling the router can help to fix technical issues associated with the network. This will help to send a fresh network IP address so that your TV can connect seamlessly. To proceed, turn off the network router and unplug the cables from the power source.
Now, wait for 30 seconds and plug back the cables into the power source. Turn on the router and allow it to set up a proper connection. It will take a maximum of 2 minutes and when connected, restart your TV and it will automatically detect the Wi-Fi network.
Method 4: Turn on DHCP
If you find that the Wi-Fi network is not showing on the list or is disabled, then you need to turn on DHCP which is Dynamic Host Configuration Protocol. It is a network management protocol used on IP networks where automatically IP addresses are assigned for communication.
To check whether DHCP is enabled on your Smart TV, take the remote and click on the Menu button. Now, get to Network Manual setup and turn on the DHCP. If it is already on, then turn it off and then back on immediately.
Now, get back to the network, tap on Network Connection > Wireless network, and verify whether the Wi-Fi network appears – if it does not, then a quick Connection Test can be performed through the network connection.

Method 7: Check the Wireless Network SSID and password
