Problem
You connect a USB convertor (for a wired ethernet cable) to your Linux laptop. It isn't working as a plug-and-play device. What could be wrong?
Solution
1. In the GUI on the Linux desktop, go to "Settings" or "Control Settings". 2. Then go to "Network".
3. Click a plus sign "+" (to add a new profile).
4. On the Identity tab, of the pop-up, there should be one or two MAC addresses in the drop down option.
5. Choose one and click "Add." Give it a few minutes.
6. If step #5 doesn't work, try again, but try a new "MAC Address" in the drop down. Give it a few minutes and see if the network is showing up.
