Wondering why Vizio TV won’t find 5G WiFi? Keep reading to learn everything!
It’s important to understand that not all Vizio TV models support 5Ghz broadband.
Some models can only connect to the 2.4Ghz network, therefore you won’t even be able to discover the other broadband of your router. Let’s learn more!
When VizioTV won’t find the 5Ghz WiFi, users should check whether dual-band WiFi is supported by their television. By going into System information on the Vizio TV, users can find out whether the TV will be able to discover the 5Ghz broadband in the first place.
Can Vizio TV Connect to 5G WiFi?
Throughout all Vizio TV models, only several are known to be compatible with 5Ghz WiFi.
That’s to say, based on the device’s network configuration, it could support a single band (2.4GHz) or dual-band (5GHz), which can reach higher download and upload speeds.
To identify whether a Vizio TV does support 5Ghz broadband we need to know the model of our TV and where to look to answer our question.
Let’s learn more!
How to Check Vizio TV Band Settings?
There is a particular characteristic you can find in your Vizio TV settings that will let you know whether your Vizio TV supports dual-band or does not.
You must head to your TV’s configuration and look for a setting that begins with “bgn”.
From the Home Screen go to Menu > Settings > Admin & Privacy > System Information.
Only the following support dual-band (5GHz) WiFi:
If by any chance you are unable to locate this setting (you’re using an old or unidentified software), call your manufacturer directly and tell them your Vizio TV serial number.
Note: The serial number should be written on a sticker at the back of the device.
How to Fix When Vizio TV Won’t Connect to 5G WiFi?
If your TV’s characteristics prove that the device is capable of making a connection with 5GHz WiFi, but you’re still experiencing issues, we have a solution!
The methods we’ve prepared down below will troubleshoot your TV for any network-related problems and get it hooked up to your home’s 5GHz WiFi.
Here’s how to fix the network problem with your Vizio TV:
Solution #1 Hard Reboot Your TV
To retry the connection appropriately, you should first hard reboot your Vizio TV.
By performing this method, also known as a “power cycle”, you will discharge the device out of any remaining electricity and give its software a fresh start. Sometimes this is all you need.
Follow these instructions to hard reboot your Vizio TV the correct way:
- Use the remote to shut down your Vizio TV and wait for 30 seconds.
- Unplug the power adapter from the Vizio TV.
- Wait for another 5 minutes while the TV is discharging.
- Re-attach the power adapter back to the source.
- Turn on your Vizio TV and give it a while to turn on.
- Go to the settings and check if you can pair the TV to the 5GHz network now.
Notice: If you keep the TV unplugged for less than 5 minutes, the power cycle won’t work!
Solution #2 Toggle the DHCP Setting
A great feature that will help with your Vizio TV WiFi problems is the DHCP setting.
What this option does is make your Vizio TV and router compatible and help them work together, hence, the connection is going to be more reliable.
To locate and toggle the DHCP setting in your Vizio TV, follow these instructions:
- Grab your Vizio TV remote.
- Enter the Menu.
- Next, scroll down a little and enter the Network tab.
- From there, select the tab that is labeled “Manual Setup”.
- In this tab, search for the “DHCP” setting.
- Highlight the setting and hit the “OK” button.
- Wait for the setting to be toggled on.
- Retry the connection between your TV and the 5GHz WiFi.
Note: If enabling the DHCP setting didn’t resolve your problem, you should keep it to the default value.
Solution #3 Verify Correct WiFi Key
As all networks require, you must enter a WiFi key to connect your Vizio TV to the WiFi.
Once a router is delivered and set up by technicians, it has a default passcode value that can be found on the bottom of the device.
However, if you’ve changed the password and forgotten it, you will have to call your ISP.
Where To Find WiFi Passcode?
If your network only consists of a dual-band network, the WiFi key will be located on a sticker on the bottom of your router.
You will have to grab ahold of the router and save the password that is written on the bottom.
There are other credentials as well but look for a field that has “PASSWORD” or just “WiFi PASSWORD” written. The key code will be there.
Once you have the correct key code, attempt to connect your Vizio TV to the WiFi.
Note: Test whether you are able to connect another device to the 5Ghz WiFi.
Solution #4 Enable Router Security Encryption
There may be a specific problem with the security of your dual-band WiFi.
Vizio TVs are well-known to work best with WPA-PSK [TKIP] encryption codex enabled.
If you have certain security features enabled on your network, this may be the reason why the Vizio TV fails to connect.
This solution will help especially when Vizio TV won’t find 5G WiFi, since certain network security settings may prevent the TV from scanning for the network.
Here’s how to enable the WPA-PSK encryption on your network router:
- Grab a PC or laptop that is connected to the WiFi.
- Open the Windows Command Prompt by writing “CMD” in the search bar.
- On the field in the CMD, type “ipconfig”.
- Copy the default gateway of your network (should be on the fields that appeared).
- Paste the default gateway in your browser.
- Use “admin” and “admin” as login credentials to open the router settings.
- Go to the “Security” tab.
- Open the “Encryptions” tab.
- Make sure that the encryption is set to WPA-PSK.
- Press Save and Exit the router’s control panel.
Once you have this encryption enabled, check if your Vizio TV is now going to connect.
Alert: Different routers/modems could have different menus. In case you’re experiencing problems, check how to enable the security encryption on your device model.
Solution #5 Reset The Television
Underlying software problems with your Vizio TV may be preventing the device from connecting with WiFi.
If that’s the case, the most reasonable thing you should try is to reset the TV to factory settings.
Note that a factory reset is going to erase all content on your TV, including apps, saved media, and data, and revert all settings to factory values.
If you’re certain that you want to factory reset the Vizio TV, follow these steps:
- Enter the Menu on the Vizio TV.
- Go to “System”.
- Navigate to “Reset And Admin” and enter the tab.
- From there, choose “Reset TV to Factory Settings Default”.
- Press the OK button on your remote.
- Confirm that you want to reset your TV.
- Wait for the reset to be completed.
Alert: Do not unplug or shut down your TV while the reset is ongoing. This may cause further complications with the software of the device.
Solution #6 Use Wired Connection
Using a wired connection for your Vizio TV is always a great option to supply internet to the device.
If everything fails to fix the WiFi problem with the Vizio TV, you should grab an Ethernet cable and connect the TV physically to the router.
For this purpose, you will need an Ethernet cable that is long enough to reach the TV from the router.
Plug the Ethernet into one of the yellow ports on your router and then into the only Ethernet port on your TV.
Your TV will prompt you to set up the wired connection and you’re all set!
Hence only Vizio TV models with a frequency range of 802.11a, 802.11c, and 802.11ac can connect to a 5Ghz WiFi. In case the TV model does support the frequency but won’t connect, users should enable the router’s security encryption and reset the TV.
Here we’ve learned why Vizio TV won’t find 5G WiFi and how to potentially solve the problem in no time.
However, in case your Vizio TV does not support the 5Ghz WiFi, keep in mind that the 2.4Ghz broadband is enough to achieve most online TV tasks without a problem!
