TCL Roku TV Not Staying Connected to WiFi – Troubleshoot and Diagnosis

If your TCL Roku TV can’t stay connected to a WiFi, here are diagnosis and troubleshooting ideas to consider:

Test Internet (WiFi)

Sometimes inconsistencies in the WiFi network can cause abrupt wifi disconnection on your Roku TV. 

Therefore, the first step is to check that your signal is stable and not dropping now and then. 

To do this, you will need a smartphone or a Windows PC connected to the network you are using:

Testing Using a Smartphone App

Using your respective smartphone, visit the Apple Store or the Google Play Store and look for network consistency testing apps.

 IOS and Android systems offer many apps to test wifi drops by pinging Google DNS

You just need to type ‘free network ping tools’ on the search bar and download the one with the most downloads and top ratings.

 Once you download this app, type ‘ping -t’ on the console and check lost packets.

Testing Using a Windows PC

You can use the command prompt to check your packet data loss using Windows PC. 

For example, if you use Windows 10, you just need to press the ‘Windows button + R keys.’ 

Once you get the command window, type ‘ping . -t’ and press ‘OK’ to check for continuous ping. 

Check if the sent/received packet data will time out to know if your network is dropping.

If you notice any ping drop, try to restart your router and check if the problem disappears. If the problem still exists, contact your ISP for a solution.

Test Your Roku TV with Another WiFi

To rule out your TV as the culprit in WiFi disconnecting issue, you need to connect it to another WiFi network. 

The easiest way is to establish a hotspot via your phone, enable the data and tether your Roku TV.

 While doing so, ensure you have enough mobile data to serve the internet. If your TV does not disconnect from the new network, the problem could be with your router or its distance. 

The best way to rule out distance is to connect your Home WiFi to your phone while near the TV. 

Also, check if the WiFi disconnection issues affect other devices to know if your WiFi has a problem.

Switch the Bandwidth from 5 GHz to 2.4 GHz

It is a settings solution and applies if your router is dual-band. Note that your Roku TV can support both 5GHz and 2.4GHz hence you may not need this step. 

However, both bands have different properties and capabilities. 5GHz is very fast, but traveling through obstacles is challenging, so your TV wifi disconnects when on it.

 On the other hand, the 2.4GHz bandwidth is slower, more stable, and can travel through obstacles. 

Therefore, changing from 5GHz to 2.4GHz can give your WiFi connection consistency.

Reset Network Connection

If you have established that your router or network has no problem, you need a network reset on your TV. 

A network reset clears all the saved networks and resets the WiFi drivers to default settings. 

This method can also help if your Roku TV cannot find or establish a connection with your WiFi. Follow the below steps to reset the network connection on your TV:

  • Pick your remote control and press the setting button
  • Once on the setting, select System setting and proceed to advanced system settings
  • Then navigate to network connection reset and select OK
  • Wait for a few seconds for your TV to reboot
  • Once the reboot is complete, re-establish and connect to your WiFi network using the already discussed steps.

Disable Network Ping and Clear Cache

Did you know your TV has a hidden menu that you can use to tweak many settings? We will use this menu to solve your WiFi disconnection issue. 

You only need a Roku Tv remote control, and I will show you the rest. But before that, let’s discuss what a ping is.

Ping, as a basic protocol, allows a device first to establish whether an IP destination is reachable. 

When your Roku TV pings an unreachable WiFi, then a connection failure occurs. 

However, this check and verification are unnecessary, and disabling it can solve TV WiFi connection issues.

Steps to turn off the ping

  • Switch your TV on and ensure it’s on it the home screen
  • Use your remote control to press the home key 5 time
  • Click the fast-forward key once
  • Then press the play key once, the rewind key once, and then the play button again.
  • Now click the fat forward key once again 
  • These steps reveal a hidden menu known as the system operations menu
  • While on this menu, select network menu and then select turn off network pings
  • Now press the Home button on the remote to hide the system operations menu.

Now the step left is to clear the cache and restart your Roku TV, and your worries will disappear.

Clearing cache and restarting

  • While on the home screen, press the Home button on your remote 5 time
  • Then click the Up arrow once, followed by the rewind key twice
  • After that, click the fast-forward key twice
  • Doing this clears the cache and restarts your Roku TV automatically
  • Once the Tv has done restarting, now try connecting again to your WiFi

Conduct Power Cycle or System Restart

A power cycle and a system restart clear all errors and bugs that can cause the WiFi disconnection issue. To troubleshoot your Roku TV using this method, follow the steps below:

  • Using your remote, press the home key to go to the home dashboard
  • Select setting and scroll to the system settings
  • After that, navigate down to the power option
  • Highlight the power option and use the right arrow to navigate to the system restart
  • Now click this button to restart your TV
  • Then unplug the Tv from the socket and let it sit idle for a few minutes
  • After waiting, power the TV and put it on

You can now try to connect to wifi and see if the problem has been resolved.

Soft Reset the Modem/ Router

This step is a simple power cycle on your modem or router to clear static charges and errors. 

To do this, just unplug your network device from the power and let it rest for about 3 minutes. Replug it back, connect its WiFi to your TV, and see if the connection has improved.

Update Router Firmware

Outdated router firmware can also cause inconsistency in your wifi connection. If your router does not update automatically, you must manually update its firmware. 

The process may vary with brands. If your router uses an app, you can easily update it using the app. 

However, if it does not have an app, run on your browse while connected to its network.

 Then input your password to access its dashboard, where you can go to the system settings and update the firmware.

Update Roku TV Firmware

Your TCL Roku TV’s outdated firmware can also cause constant disconnection. You can follow the steps below to update it:

  • While on the Home dashboard, go to the settings
  • Navigate to the system, then system updates
  • Click Check now to find new updates
  • Once you find them, ensure your network is stable and select Install now

Use Wired Connection

If you have tried different WiFi solutions to no avail, consider using a wired connection via ethernet cable. 

You connect one end of the cable, your router, and the other to your TV. You can use a USB ethernet adapter if your TV does not have an ethernet port. 

Then set your Roku TV network to be wired instead of wireless, and you are done.

Factory Reset Your Roku TV

Factory resetting can fix any setting errors and bugs causing your disconnection. 

However, use this method as the last solution since it erases all your data, including apps and settings. To factory rest, follow the steps below:

  • Using the remote, click the Home button>Settings>System> Advance system settings, then Factory reset. Then enter the code displayed on the screen and press OK.
  • You can also locate the reset button on your TV and use a pin to press and hold it for about 20 seconds. Once the TV goes off, hold it until it turns back on and displays the Roku log.

Contact Roku Customer Care

Lastly, you can contact Roku customer service when all the methods have failed. Then explain your issues and follow their advice.


You can get your Roku TV back online with the above well-researched solutions. You need patience, follow the instructions carefully, and continue your streaming seamlessly.
