Numbers in the network adapter

[MrRichard]

What is different:
Intel r ethernet connection (2) i219-v
From
Intel r ethernet connection (12) i 219-v

If suddenly someone knows what it is and knows if it is possible to somehow roll back the figure, then I will be grateful

These sequence numbers are used to ensure that the name is unique. Upgrades/reinstalls/etc. will cause the numbers to be incremented. This discussion covers the elimination of these numebrs: https://superuser.com/questions/323331/how-to-get-rid-of-auto-generated-sequence-number-in-networks-device-name-in-win.

Hope this helps,
