I have an Asus Z170 Pro Gaming motherboard with the I219-V LAN port but even on a fresh Windows 7 or Windows 10 installation, the port always shows up as having the (2) prefix even though its the only LAN port available and its the first time drivers have been installed for it (for that OS installation after formatting the HDD). The driver version I'm currently using is 12.15.25.6 from earlier this year.
I'm pretty sure that at some stage I've seen it as simply Intel(R) Ethernet Connection I219-V and I'd like to get back to that but how? FWIW the hardware is working fine, I'm just fussy about my system configuration and would like this to be as originally intended.
