Hello, for the last month or so wireless casting (Windows key + K) on our Samsung TV stopped working with all our Windows 11 laptops (we have 70). However, it's still working with a Windows 10 laptop that isn't connected to our domain...it's also working with Apple Airplay so the issue is not the TV. (I did a factory reset on the TV just to make sure anyway).Whenever we try to connect a Windows 11 laptop, we can approve the connection on the TV and it tries to connect for like 10 seconds but ultimately it fails and says that it can't connect (yes it's on the same WIFI network.) I don't know why it suddenly stopped working, we haven't changed any policy recently. Could it be a Windows update? Does anyone have any idea?

BMERCIER45 Add me to the list of frustrated. Used casting extensively until a couple of months ago on my Windows 11 machine. Stopped working after an update just nt sure which one. Wife's Windows 10 laptop connects immediately. Connecting to WebOS LG TV for years but this is my first Win 11 machine.

Mine also does not work. Frustrating

I have the exact same issue - did you ever get a resolution? thanks

BMERCIER45 any update on this? I bought a windows 11 laptop in febuary and the casting has never worked and didnt know this was a new issue. It does exactly like you desceibed, tries to connect but fails. Also on a samsung tv.

It sounds like your issue with wireless casting on Windows 11 laptops could indeed be related to a recent Windows update or a network setting. Here are some steps to troubleshoot and potentially resolve the issue: Check for Windows Updates: Ensure that all Windows 11 laptops are fully updated. Sometimes, new updates might fix existing issues. Go to Settings > Windows Update and check for updates. Rollback Recent Updates: If the problem started recently, it might be due to a recent update. Try rolling back the latest update on one of the laptops to see if it resolves the issue. Go to Settings > Windows Update > Update history > Uninstall updates and choose the latest one to uninstall. Network Configuration: Since all laptops are on the same Wi-Fi network, ensure there are no network policies or firewall settings that could be blocking the connection. Check your network’s firewall settings and any domain policies that might affect network discovery or casting. Update Wireless Drivers: Ensure the wireless drivers on all Windows 11 laptops are up to date. Open Device Manager, find the wireless adapter, right-click, and select Update driver. Windows Features: Ensure that the necessary Windows features for screen mirroring are enabled. Go to Settings > Apps > Optional features and ensure that "Wireless Display" is installed. Reset Network Settings: Try resetting the network settings on one of the Windows 11 laptops. Go to Settings > Network & Internet > Status > Network reset. Troubleshoot Network Adapter: Use the built-in troubleshooter to identify and fix network-related issues. Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Network Adapter. Check Group Policies: If the laptops are part of a domain, ensure that no group policies are interfering with the casting functionality. Open Group Policy Editor and review policies related to wireless display and network sharing. Re-enable Wireless Display: Disable and then re-enable the wireless display feature on one of the Windows 11 laptops. Go to Settings > Devices > Bluetooth & other devices > Add Bluetooth or other device > Wireless display or dock. If these steps do not resolve the issue, it might be worth reaching out to Microsoft Support for further assistance or checking the Microsoft community forums for any similar issues reported by other users.Thanks (external link removed by moderator)

I found out what was causing my problem with wireless casting to my Samsung TV from my Lenovo laptop. It had to do with my Norton app. There is a setting for "Smart Firewall" within the Advanced Security settings. Once turned off I am able to wirelessly cast to my TV. You can turn off the setting for a specific amount of time. You obviously need to turn it back on after you are through casting.

I had microsoft remoted into my laptop (HP) Windows 11 and they could not get the issue resolved either. This was quite disheartening. Anyway, I may be contacting them back, but the last thing they told me was to check with HP so I am going to do that. I am also going to bring up my Lenovo laptop and try that as well.

More clarity on my issue with casting on 2/21/2025. I did do the February 2025 patch tuesday updates. I can start the process of casting to a Roku device. The roku device shows up. It acts like it is going to mirror my screen just fine, but it never shows anything from my screen and the screen turns black. Thus it does not work any more. It was working fine two to three weeks ago.

Same problem. I am sure it started with a Win 11 update.

  I have the same problem here 2/21/25. I did do the February 2025 patch tuesday update. Casting was working a few weeks ago. Likely got wrecked due to the windows updates of Feb 2025.

I have a strange addition. Settings >> Cast refuses to find any device, however - Chrome browser - with YouTube connects to both my Cast devices (Smart TV and BT/EE STB)
