I have a weird question (usually it's the other way round) but is there a way to fool my Ubuntu installation into thinking that there is no network connection? I only want to establish a network connection when using a USB WiFi dongle. I don't want the computer to see any other adapters (whether plugged in or not).

How do I disable my gigabit ethernet port and all sub-layers (Don't even want the adapter to be "found by hardware")?

In increasing order of medievalness:

  1. tell network-manager to ignore the device by unmanaging it based on its MAC address
  2. blacklist the kernel module for the device, so that the kernel won't load the driver
  3. disable the device in the computer's BIOS

I've used 14.04 as recent as yesterday but never had your need. I'm using 12.04 at the moment, so this might not apply. Please right click on your internet connection icon at the top of your screen and where you see, "enable networking" check, uncheck that.

If that's not what you want to do, please clarify.
