Why is Roku Screen Mirroring not Working in Windows 11?
Roku TV’s screen mirroring might not work with Windows 11 due to the firewall blocking, or the connection is not private. Backdated Windows or device drivers can cause screen cast problems too. Bluetooth remains active for a long time can cause lag in the system, and this is also responsible.
Screen mirroring or casting is a great technology to share multimedia such as pictures, movies, or videos wirelessly from one device to another. TV is the most used device for sharing your laptop or mobile screen.
Modern TVs are smart enough to handle all sorts of multitasking, like browsing the internet and watching movies through stream services. Roku steps up this feature furthermore by giving extra portability and flexibility.
But you can sometimes face problems with Roku. Screen mirroring not working with Windows systems is one of them. I have already told you the reasons behind it, now let’s jump into the fixing part.
How to Fix Screen Mirroring not Working in Windows 11
Screen mirroring not working with Roku is a minor issue. You don’t need to be a pro or take your Roku TV or device to the technician to solve this simple issue. There are simple ways to resolve this without taking too much hassle. I have found the quickest way, and let me share with you the methods.
Here are the methods to fix screen mirroring not working with Windows 11:
1. Changes Settings from Third-party Antivirus
Antivirus has many features for protecting the system and blocking functions to block malware. Sometimes antivirus can treat some functions as untrusted. While trying to mirror your Windows screen, third-party antivirus can block the process.
The firewall might block the screencast to Roku TV. So, you need to change the firewall settings to continue the mirroring process.
If you use third-party antivirus apps like Avast or McAfee, turn off the firewall and try casting the Windows screen to Roku TV again. You wouldn’t face this again if the firewall was blocking the connection.
Another factor from the antivirus is also responsible for creating this phenomenon. When third-party antivirus blocks the screencast due to a trust issue, you must disconnect the Roku TV from your laptop or desktop and reconnect it.
The antivirus (Avast, McAfee) firewall UI will display a popup message. Now, change the network from Untrusted to Trusted. Next, you will find screen mirroring is working perfectly.
The last thing you can do is restore the antivirus to the default settings. Then reboot the PC and make sure the firewall is on after a restart. Connect Roku TV/device with your Windows laptop again. Hopefully, you won’t be disappointed this time, as the mirroring connection will run smoothly.

2. Reconnect the Roku Device
Reconnecting the Roku device is the easiest thing you can do to fix the issue. Sometimes Roku devices or other paired devices can get stuck due to remaining active for a long time. So solving this is possible by reconnecting and establishing all the pairing again.
Here are the steps to reconnect the Roku device:
- Press the Win key + I and select Bluetooth & devices.
- Click on the three dots from the device’s upper side and select Remove Device.
- Turn off Bluetooth.
- Restart the PC and turn on Bluetooth again.
- Go to Add device and search for Roku TV again.

After reconnecting the Roku device with your Windows laptop, you can cast the screen again. Sometimes reconnecting or repairing is needed when Bluetooth connectivity is active for a long time.
3. Update Windows
Backdated Windows can bring trouble while connecting with the latest devices. The latest device does need the newest OS to establish a reliable and smooth connection. You might face failure when trying to connect your Roku device with your backdated Windows OS. So, update your Windows to the latest release.
Here are the steps to update Windows:
- Press Windows Key + I and click on Windows Update from the bottom.
- Click on Check for updates.
Now, the Windows system will check for available updates and download them automatically. After downloading, the system will install them too.
Then restart the PC to finish the updating process. Reconnect the PC’s screen to the Roku device from the settings again. Hopefully, you will see success this time.

5. Switch your Network Settings to Private
Some connections do not support networks with public mode on. Private mode is best for connecting indoor devices with wireless or Bluetooth. In contrast, the public mode makes Windows more protected and defends every other connection.
Sometimes defender blocks known networks for security purposes when you are on public mode. That’s when you face Roku screen mirroring not working in Windows 11. So, you must switch to private mode to fix this.
Here are the steps to change network settings to private:
- Press Windows Key + X and select the Settings app.
- Click on Network & internet.
- Navigate to Advance network settings > Advanced sharing settings.
- Click on Public network and turn it off.
- Click on Private network and turn it on.
- Reboot the PC.
- Pair your Windows laptop with the Roku device again.
After applying the above steps, I hope you successfully fixed the screen mirroring problem with Roku devices.
Pro Tip: Restart the router and the modem. As you know, a casting screen is a wireless display function that works through Wi-Fi or ethernet cable. So, restarting the router or modem will fix the issue.
