Windows 10 devices cannot ping each other

[JJeff17]

I have two Windows 10 computers. We'll call them A and B.

A has an Intel AX200 160Mhz card with driver version 21.90.3.2. B has something else.

A and B will be happily communicating with each other when suddenly and without warning the communication fails. The following two entries are recorded in A's eventlog -

7021 - Connection telemetry fields and analysis usage

7003 - Roam Complete

At this instant A and B can no longer ping each other (or communicate in any way).

During this time -

A and B can both reach the internet.

A and B can both ping the router.

The router can ping both A and B

A and B can ping other devices on the network

But they cannot ping each other. Or communicate in any way. SMB, etc.

I spent MANY HOURS screwing with network and firewall settings before I figured out it was the AX200 card in host A.

This has actually happened with both the on-board AX200 card in A's motherboard, MSI MPG X570 GAMING PRO CARBON WIFI and a separate PCI card, a TP-Link WiFi 6 AX3000 PCIe. Both use the AX200 chip.

My network is an Asus RT-AC88U with an Asus RT-AC68U in wireless mesh (AiMesh) configuration.

I've used the recommended settings at https://www.intel.com/content/www/us/en/support/articles/000024678/network-and-i-o/wireless-networking.html

They did not help.

I think the driver is bugged.

The "fix" is to disable the AX200 in the Device Manager and then re-enable it. Then A and B can ping each other again.
