Why did my j5create adapter stop working?

I had my macbook pro and macbook air connected to ethernet using a j5create adapter that was recommended on this forum. It worked fine for several years for my son as well with his macbook air. All of a sudden a few months ago mine stopped working. j5create replaced my adapter because it was still under warranty. The new one did not work. I tried everything I know to do to make it work both times before calling j5create. They had me go through all the same steps I had done to no avail. Now my son's adapter stopped working.

The ethernet connection appears when the cable is plugged into the adapter and the lights are on like always. Just no connection to any web site using any browser works. It always just times out.

Is there a workaround for this or did apple and/or j5create make it so they would just stop working now?

MacBook Pro 13″, OS X 10.11

This looks difficult to some but is pretty easy taken step by step...

Make a New Location, Using network locations in Mac OS X ...

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

Sys Prefs>Network>highlight the Interface you're using>Advanced>TCP/IP>Configure IPv4: Using DHCP.

If using Wifi, instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

System Preferences>Network>choose interface>Advanced>Proxies Tab, make sure none are set, like for HTTP & HTTPS.

System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

8.8.8.8

8.8.4.4

1.1.1.1

9.9.9.9

It is very simple, thank you. I had to do this years ago so I am familiar with the process.

We did it all step by step and it still won't let a browser navigate anyplace. Are we supposed to have the j5create not plugged in at first and then plug it in when it's time to select the Ethernet option? Or does that not matter?

It needs to be connected to affect the setting for that port. :)

All the Settings including & following this are specific to the Interface you choose...

The interface that connects to the Internet should be dragged to the top of the list.

We did re-try this with the ethernet cable not connected. Once the Apply button was clicked, we plugged in the ethernet cable and still could not navigate anyplace in a web browser.
