Windows 10 Not able to connect to an external wireless display nor able to project to my pc.

[Anshul Joshi]

A few months back I tried to cast my android phone to my laptop using the built-in app in my phone and the 'connect' app on windows 10 and everything was working fine. Still, now if I am trying to do the same thing my laptop is not being detected as a wireless display neither I am able to connect(cast) my laptop to another device like a smart tv or another laptop. I tried the same thing with my brother's laptop and everything is working fine, I am able to cast my phone to the laptop and able to cast that laptop on smart tv, whenever I try this I always get this message on top "couldn't connect to your device try to reconnect through the action center". I think all these problems happened after a few series of updates from windows. Basically, all connection requests on my local network inbound or outbound are being rejected. But the FTP server created on my android phone is the only thing that seems to be working fine, I can create an FTP server and browse files by visiting the FTP network location. I need to fix this issue because I connect(cast) my office laptop to my personal laptop so as to use it as a second display.

It seems like you are encountering connectivity issues with casting your device screens to each other wirelessly. Here are some troubleshooting steps you can follow to resolve the problem:

Ensure Devices Meet Requirements:​

• Wi-Fi Compatibility: Ensure both devices (phone and Windows laptop) support Wi-Fi Direct or Miracast for screen casting.
• Software Updates: Update the drivers and the operating system on your Windows laptop to ensure compatibility.

Troubleshooting Steps:​

1. Check Wireless Connections:
   • Verify that both your phone and laptop are connected to the same Wi-Fi network.
   • Test with mobile hotspot on your phone if possible to rule out issues with your Wi-Fi network.
   []Firewall and Antivirus:
   • Temporarily disable the firewall and antivirus software on your laptop. Sometimes, security software can block casting functionalities.
   []Reset Network:
   • Reset the network settings on both the phone and laptop to ensure a fresh connection.
   []Restart Devices:
   • Power cycle your phone and Windows laptop. Turn them off, wait a few minutes, and then power them back on.
   []Check "Connect" App:
   • Reconfirm that the "Connect" app settings on your Windows laptop are configured correctly and not set to block wireless casting.
   []Reconnect Devices:
   • On your phone, forget the previous connection and try reconnecting the laptop as a wireless display device.
   []Driver Update:
   • Update the wireless adapter drivers on your Windows laptop. Visit the manufacturer's website to download and install the latest drivers.
2. Check Third-Party Apps:
   • Ensure no third-party software or settings are conflicting with the casting feature on your laptop.

Additional Tips:​

• The 'Connect' functionality might be triggered with specific hotkeys, such as Win + K, so try invoking it using these shortcuts.
• If the issue persists, you may consider resetting the Windows network settings or seeking assistance from Microsoft Support for targeted troubleshooting.

By following these steps and ensuring both devices are configured correctly for wireless connectivity, you should be able to resolve the casting issue between your phone and laptop.
