Connecting to OBD port on my car with ethernet cable

[Art_Layton]

Here is my situation. I have a new Dell laptop running Windows 11. There is no ethernet port on the laptop. So I have an adapter that allows me to connect a RJ45 (ethernet) cable to the USB port on the laptop. The other end of the cable is plugged into my OBD port on my car. I have a program on the laptop that modifies the DME setting on my car. It should automatically connect to this program after I plug everything in and start the car. It doesn’t. Anyone have any idea how to tell the laptop that the USB port is the ethernet connection?

It would help if we knew what adapter you are using

I have a program on the laptop

Have you used this program before?
It may be an rj45 but could be a special wiring.
If you have used it before with a patch lead then ok
If not what program so we can check if special cable needed

I have used this program before (bootmod3) . I am using an OBD to ethernet cable I have used before with no problem. The adapter to connect this cable to the laptop is a “USB to gigabit ethernet adapter” made by Cable Matters.

I did notice a setting I hadn’t seen before in settings. I click on “network and internet”, then click on “advance network settings”. I then click on “ethernet” and change disable to enable. Do you think I have to make this change?

BTW, thanks for your quick response.

and change disable to enable. Do you think I have to make this change?

Yes

Think I figured out the problem; I need to turn off windows defender and malwarebytes.
