Enhancing Wireless Display Connectivity After Setting Up a New Wi-Fi Router: Troubleshooting Tips

Introduction

Upgrading your Wi-Fi network can significantly improve internet speed and connectivity. However, such changes may inadvertently disrupt existing device integrations, such as wireless display connections between your laptop and smart TV. If you’ve recently switched to a new Wi-Fi router and found that your wireless display setup is no longer functioning, you’re not alone. This article explores common causes and effective troubleshooting steps to restore seamless wireless display functionality.

Understanding the Issue

Wireless display technology, such as Miracast or Miracast-based features like Samsung’s Smart View, relies on devices being discoverable and connected within the same network environment. Changing your router’s settings or replacing it may affect network visibility or communication protocols, leading to devices no longer appearing in the list of available displays.

Scenario Overview

• Devices Involved:
• Samsung 24” N4300 HD HDR Smart TV
• Samsung Galaxy Book2 Pro 360 (Windows 11)
• Smartphone (Samsung Galaxy S24 Ultra)
• Network:
• Previously connected via a different Wi-Fi router
• Currently using a new EE Smart Hub Plus router
• Observed Symptoms:
• TV no longer appears as a wireless display option on the laptop
• Smooth connection via Smart View on phone remains possible
• No changes made to device hardware or software besides the router swap

Troubleshooting Steps Undertaken

1. Removing and re-adding wireless display features on the laptop.
2. Resetting Wi-Fi connections on both the laptop and TV.
3. Confirming network profile settings (private vs. public) on Windows 11.
4. Logging into the router to check for features like ‘Client Isolation’ (which isolates devices from each other on the network).
5. Ensuring UPnP (Universal Plug and Play) is enabled, facilitating device discovery.

Observations

• Despite these efforts, the TV remains undiscoverable as a wireless display.
• The only significant change in the environment is the new router’s installation, indicating network configuration may be the culprit.

Potential Causes and Solutions
