Power cycling is a simple process that can fix a variety of problems with your TV — from slow performance to flashing screens. While you can usually solve these by unplugging the TV and turning it back on again, sometimes that isn’t enough, which is where a power cycle comes in.

  6. Wait for it to fully start up, and check if it resolve the issue.

3. Toggle the DHCP Settings

If your WiFi keeps cutting out and connecting only when you restart it, your internet router might have duplicate IP addresses.

DHCP is a networking protocol that’s used to assign devices IP addresses. When two devices attempt to connect to the same network, their requests get sent to the router at the same time. Since it’s unable to differentiate between them, both devices will be given the same IP. This means they can’t access the internet.

When you put your device on the network, sometimes it is possible that two or more devices have the same IP address. If that happens, your internet stops working and WiFi won’t connect correctly.

Enabling the DHCP in your Vizio TV is an important step to ensure that you’ll have a WiFi connection.

  1. Press and hold the Home button, then press OK.
  2. Scroll up and select Manual Setup, then press OK.
  3. Select DHCP, then press OK.
  4. Select Enable, then press OK.
  5. Press the Home button again to close the menu window.

Once you enable the DHCP settings on your TV, save the settings. If the error persists, check your internet connection and try again.

NOTE: If you’re still having difficulty, try disabling your smart TV’s “DHCP” (Dynamic Host Configuration Protocol). After a couple minutes, turn it back on.

4. Change Router Settings to WPA-PSK [TKIP]

Make sure you’re updating your network configuration to WPA-PSK mode for the best SmartCast performance.

To do so, you’ll need to connect your Vizio SmartCast TV to the Internet using an Ethernet cable. After entering the home menu on your TV, select Settings > Network > IP Settings > IP Mode and make sure it’s set to WPA-PSK [TKIP].

Vizio TVs need a strong and stable WiFi connection to be able to use SmartCast. If you are having problems connecting your Vizio TV to your router, you can try resetting the gateway setting on your TV.

NOTE: Changing your router’s encryption type can cause problems. Talk to your ISP about changing it.

5. Change WiFi Password

Sometimes, networks are busy — with all the devices you have. We may have to change your WIFI password so that only we can use it. The TV can’t connect to your WiFi router. Yes, it’s a problem that requires an easy fix: switching the router password. Most routers have a default password that you can easily change — and when you do, it’ll make sure the TV is connected to the internet.

Make sure your router is turned on, and then open its Cpanel. There, you’ll find the Default Password. Change it to something you can remember easily! Now that you have your router’s IP address, enter it into network settings of your phone. After that, connect to the internet!

6. Use Wired Connection

Though it might sound like a long shot, one of the easiest ways to resolve issues with your Vizio SmartCast TV is to simply attach an ethernet cable to its port. If your TV has this capability, simply plug it into your router or modem and see if the connection improves.

If your TV has an ethernet port on the back, plug it into your router or modem with an ethernet cable. If you’re able to connect to the internet through an ethernet cable, then your WiFi adapter is broken.
