TCL Roku TV not connecting to the internet! The fix

You can only enjoy watching your TCL Roku TV once you connect it to the internet. You can do this via Wi-Fi or by using an Ethernet cable.

Generally, Roku TVs scan for a wireless network automatically during the initial setup and in subsequent uses. But if you cannot connect a TCL TV to the internet, you may need to troubleshoot the issue to find a solution.

But why won’t my Roku TV connect to the internet? Ideally, your TCL Roku TV is not connecting to the internet because of an issue with your network, router, or the device itself.

You may also find it challenging to watch content because your bandwidth does not support 4K streaming.

In other cases, the problem could occur because your ISP is experiencing some technical issues. If you are unable to connect to the internet, there are a few different things you can try:

Restart your TCL Roku TV

Restarting your Roku will help to refresh the device and its connections and start anew. Here is how:

  • Press the home button on your remote to open the main screen.
  • Scroll up or down and select Settings.
  • Press the right arrow button and select System.
  • Press the right arrow button and select Power.
  • Hit the right arrow button and select System Restart.
  • Press the right arrow button and select Restart.
  • Press the OK button to confirm.

It will take a few minutes before your Roku TV restarts. Once done, try opening a webpage.

Check the signal strength on your Roku

Is your Roku TV is connected to Wi-Fi but not working? Try to solve this issue by checking the signal strength of your network.

  • Go to Settings.
  • Select Network.
  • Select Signal Strength.

If you see your signal strength labeled as Excellent, it means your connection can load any internet page. Otherwise, click on Check your Internet Speed.

Check your bandwidth requirements

The minimum bandwidth requirements for streaming 4K content will vary from the streaming provider. For example, you need at least 25 Mbps to watch 4K videos on YouTube and Netflix.

Vudu requires 11 Mbps, and Amazon is 15 Mbps. If your internet is below these values, consider upgrading to a higher speed.

Connect via the Ethernet cable

When you have a problem with TCL Roku TV not automatically connecting to Wi-Fi, connect the device to the internet via the Ethernet cable.

This is what you need to do:

  • Locate the Ethernet port at the back of your TCL Roku 4K TV.
  • Plug in an Ethernet cable coming from your router or modem to the TV.
  • Press the Home button on your remote to open the main screen.
  • Scroll down and select Settings.
  • Press the right arrow button and select Network.
  • Press the right arrow button and select Wired (Ethernet).

The device will verify connectivity to your local network and the internet. If you don’t have one, consider getting the DbillionDa RJ45 Cat8 ethernet cable which is durable and affordable.

Understand that most Roku TV models scan for wireless networks automatically except for 4K models.

If you are using a 4K TV, it will prompt you to select the method you will be using to connect to the internet during the initial setup.

Restart your router

Restarting your router helps to establish a new connection from your ISP. The best way of doing it is to remove the power cable, wait for a few minutes, plug it back in, and try again.

How to solve wired connection not working on TCL Roku TV

In some cases, your TCL Roku TV fails to connect to your wireless network. When that happens, try to troubleshoot it as follows:

  • Check that you have entered the correct password for your wireless network. Note that passwords are case-sensitive.
  • Check that you have selected the correct wireless network name.
  • Check whether you have turned on MAC address filtering. If that is the case, you will need to adjust the ACL/MAC address filtering.

ACL/MAC address filtering allows you to add specific wireless devices to your wireless network. If you want to add your MAC address to the MAC filter list or disable the option altogether, you will have to refer to your router’s user manual.

TCL Roku TV disconnects from Wi-Fi when turned off? The fix

You can solve this issue by resetting your Roku TV and setting up your wireless connection again. Follow the steps below:

  • Go to Settings.
  • Select System.
  • Select Advanced System Settings.
  • Factory Reset.
  • Highlight Factory Reset Everything.
  • Enter the code listed on the screen.
  • Select OK.

A factory reset will remove all the configurations you made on your TV settings. That means you will have to go through the setup again, including Wi-Fi.

Follow the second stage of completing your wireless connection setup. Before you begin, ensure you have the correct wireless network name and password. Then:

  • Press the Home button on your remote to open the main screen.
  • Scroll down and select Settings.
  • Press the right arrow button and select Network.
  • Press the right arrow button and select Wireless.
  • Your TV will start scanning for any available wireless network.
  • Scroll down and select your wireless network name from the list.
  • Press the OK button.

If you have a password-protected network, use the on-screen keyboard to enter the password.  Next, scroll down and highlight Connect, then press the OK button.

Your TV will download software updates automatically. If other devices keep disconnecting too, then you might need a replacement router.

Check the location of your Roku TV

The placement of your Roku TV can have an impact on the streaming quality. You can optimize the performance by doing the following:

  • Place your Roku TV within the range of your router.
  • Move or rotate your TV into different positions.
  • Avoid placing your streaming device in a recessed or enclosed area.
  • Disconnect other devices that are using the same network to connect to the internet.

You can also ensure optimal quality by connecting your TV to the internet via Ethernet.


If your Roku TV loses Internet connection when streaming a video, check to ensure there is enough signal strength to your device.

You can also troubleshoot the problem by restarting your TV and router, connecting via the Ethernet cable instead of Wi-Fi, and placing your player within the range of the router.

Some advanced fixes include factory resetting your TV and adjusting the ACL/MAC address filtering on your router.
