My internet and ethernet broke after the latest win 11 update (Alrady fixed)

I just reinstalled my vpn app (it apparently self activated a killswitch feature) so yeah. Reinstall any app that does something with your wifi/firewall

Same or very similar here. I have a very powerful desktop server and many Hyper-V virtual PCs. I have all my host and virtual PCs configured to only install a security update after a month, and feature updates after a year, to hopefully avoid bugs like this.

After the updates (October's security update) I performed in the last couple of hours on the host PC and two of the virtual PCs, no matter what I do, I can RDP into the virtual PCs from it's host or my regular desktop, but I can't RDP into the host PC, and even though I can access several important drives locally on the host PC, I can't access them through the network from either of the virtual PCs running on the same computer, nor from my regular desktop.

Oh, another thing. On my virtual PCs, I had to configure them again to recognize the Ethernet connection as a private connection, but on it's host PC, it fails to turn network discovery even on, much less get back to seeing it as a private network. This might explain the shared network resources not being able to be seen, but doesn't explain why I suddenly can't turn network discovery on, only on the host desktop server. Using a server-level Intel 10 Gb Ethernet card, the X540-T1, too.

I'll be manually checking for a new driver, although I don't expect that to be the answer since I can access the internet just fine from all referenced PCs.

Edit: I was able to update the Ethernet driver, but still no luck turning network discovery back on. I'm now manually updating to November's 25H2 update, and I'll see if that solves any issues. 25H2 did not solve the issue. ARGH!

Edit 2: I had to reinstall Windows, as I couldn't go any days with the computer not up and running. I installed Windows 11 25H2, and applied all updates to the ISO before installing it to the desktop, and all is working again.

No. Microsoft didn't give me an answer. And yes. I did fix it. It was my VPN software's Killswitch self activating out of nowhere. So maybe reinstall your vpn/antivirus to try to repair it or ur network card might be fried or it could be window's fault or your system's fault. But any software that messes with your wifi/ethernet should be reinstalled

Can we get an Update on this? Did you get it fixed? or did Microsoft tell you how to fix it?!

I am so sick of Microsoft forcing updates on us that break our machines! My network card doesn't work at all now I only have Wi-fi. Everything was working great before the update, but it kept nagging and nagging to me to update. I want to turn this function off. The only updates I ever want are security updates. I don't want all this new crap that Microsoft is forcing onto US!

It seems you are experiencing issues with your internet and ethernet connectivity after a Windows 11 update. This could be related to a known issue where server-side applications that rely on HTTP.sys may experience problems with incoming connections, which can affect network functionality. Here are some steps you can try to resolve the issue:

Check for Updates: Open "Windows Update" in the "Windows Settings" app. You can do this by typing "check for updates" in the start menu and selecting the result. Click on "Check for updates" and allow any updates to install.
Restart Your Device: Even if no updates are installed, it's essential to restart your device to ensure all changes take effect.
Network Adapter Troubleshooter: Use the built-in network troubleshooter to diagnose and fix network problems. You can find this in the "Settings" under "Network & Internet" > "Status" > "Network troubleshooter".
Reset Network Settings: If the above steps do not work, consider resetting your network settings. Go to "Settings" > "Network & Internet" > "Status" > "Network reset". This will remove and reinstall all your network adapters and set other networking components back to their original settings.

If these steps do not resolve the issue, it may be beneficial to check for specific driver updates for your network adapters or consult the manufacturer's support for further assistance.
