Lost Network Connectivity, Kind of

I just reinstalled windows on my ASUS Z790-P WiFi. It was all looking good until after one of the Windows Updates. After that updat I no longer had internet access. I could also not ping any of the other computers on my LAN.
"PING: transmit failed. General failure."
That is an error response that looks diffeent from a typical Ping failure. I have a Realtek Lan 2.5 GbE port and a 2 port 25GbE Mellanox AOC, and an on-board wireless. None of the 3 connections worked. I hooked a laptop up to the ethernet cable, and it worked fine, so the local switch is ok.

Out of curiosity, I tried to Remote Desktop Connection to the other computers on my LAN and surpries surprise, it worked, even though I couldnt even ping them. I have no other software loaded on the computer except the ASUS drivers from their web site and the standard Windows 11 Pro updates that get loaded in a reinstall. I have installed windows on 40 different computers over the years, so I am not a newby, but I am not a network expert either. I am at a loss on where to go except to start from scratch again. I have uninstalled all of the windows updates, but the network connections have not been restored.

Ping uses the ICMP protocol so it's not required to actually connect to a system with SMB or RDP for example. I would start by checking which profile is in use on all your nics.

You can use PowerShell’s Get-NetConnectionProfile and Set-NetConnectionProfile cmdlets.

If they are on the public profile you will want to set them to private

A firewall or firewall rule can block ICMP packets, while allowing other types of traffic to pass.

Run this command from PowerShell to list any firewall rules which are blocking ICMP:

Thanks for your response guys. I checked on the Profile, and they were set to public. I set them to private, and checked to make sure that they were, but that did not help. Still no internet access or ping response.

I tried the -NetFirewallPortFilter, and it seemed to run, but did not return any response. It just dropped down to the next line.

I think that it will be faster to just try a reinstall, something in the windows update must have gotten corrupted, because it was working fine before the last update.

That sounds like overkill. Have you tried simply removing the update to see if that resolves the issue, also if it's just ping that doesn't work that won't impede usability of the computer
