I am having issues with my new network interface card (NIC) and my on-board NIC is still enabled. What do I do in Windows?

Sometimes an on-board network interface card (NIC) conflicts with a new NIC.  In these cases it is best to disable the on-board NIC.

The best way to disable your on-board NIC is to go into your BIOS and disable it there if possible.  To do this, consult your motherboard manual.

You can also disable any NIC in Windows.  Here is how you do this:

First click Start, or, in Windows 10 and 8, hold down the Windows key and press X.  Then click Control Panel.

1. Click Network and Internet.
2. Click Network and Sharing Center.
3. On the left, click Change adapter settings.
4. Right-click the NIC that you would like to disable and select Disable.

Windows 8

1. Click Network and Sharing Center.
2. On the left, click Change adapter settings.

Windows 7

2. Click Network and Sharing Center.
3. On the left, click Change adapter settings.
4. Right-click the NIC that you would like to disable and select Disable.

2. On the left, click Manage network connections.
