On July 19, 2022 I was away from my Laptop. On July 22, 2022 I reset the network and since then I noticed that the Wireshark Interface_ID had changed.

I used Wireshark last on July 17, 2022-This is the normal Interface_id number.

Frame 1: 60 bytes on wire, 60 bytes captured on interface \Device\NPF_{xxxxx-6911-xxxx-xxxx-xxxxxxxx-xx}, id 0

On July 22, 2022 I use Wireshark and The interface_id number changed. What would of caused this to change? This is what it is now.

Frame 1: 554 bytes on wire, 554 bytes captured on Interface \Device\NPF_{xxxxxxxx-C1FF-xxxx-xxxx-xxxxxxxxxxxx}, id 0

In Preferences>Capture the first one is shown. Yesterday, I could see both of them, but that changed all of a sudden. Then, I could only see the older Interface \Device\NPF number. I also checked the Options on interfaces and the old interface number is not there either. I would have to re-type it to add it in. First I would like to know how this happened?

Thank you so very much...

What did you to do "reset the network"? If it caused Windows to forget about your existing network adapter and then rediscover it, it would probably assign a new UUID/GUID to it, which would change the name of the interface.
