Windows 7: Wifi DHCP - the second network card on a fixed IP

Wifi DHCP - the second network card on a fixed IP

I warmly welcome

I have a problem with configuring network cards

WIFI comes nicely with DHCP pool 192.168.0 .*

I have a virtual network adapter "Microsoft Loopback Adapter"
in it I have to have a static IP address
and set it manually (IPv4)

the problem is that the WiFi card is still changing my IP address of the virtual card

how to prevent it?

I wanted to wifi card automatically collects the IP address
but did not interfere in the virtual adapter's IP

I quote (from ):

Microsoft Loopback Adapter is a dummy network card, no hardware is involved. It is used as a testing tool for a virtual network environment where network access is not available. Also, you must use the Loopback adapter if there are conflicts with a network adapter or with a network adapter driver. You can bind network clients, protocols, and other network configuration items to the Loopback adapter, and you can install the network adapter driver or network adapter later while retaining the network configuration information.
Given that, there is no way your wi-fi card can "change" the IP address of your fake network adapter. If you set a static IP for ANY adapter, it WILL stay that way, regardless if one adapter is set to release and renew based on DHCP and one is not.

I even tried it myself. I installed the loopback adapter, set an IP and all that for it, released ALL DHCP'd IPs and renewed them. the static IP for the loopback adapter didn't change.

Take a look at your settings again, make sure you didn't miss something.
