Is there any major difference between Nexiq 1 and Nexiq 2 as the price difference isn’t much?

Nexiq 1 is the past, Nexiq 2 is the future.

Nexiq 1 is discontinued. no more updates but for most people it will still work just fine.
Nexiq 2 is the current model and has more future potential than what the Nexiq 1 could do.

Cables for each are different so they are not interchangeable. When ordering, you should make sure you get 3 different cables. The standard 6/9 pin y-cable with the green connector on the 9 pin plug so you can communicate to the newer 500k baud network. A standard OBD2 cable and an OBD II Cat cable to talk to Caterpillar engines in GM trucks. If you need to communicate to trailer ABS, you will also need a PLC adapter.

Do NOT buy the inexpensive clones that normally come with multiple cables. The clones are not reliable and if they update with Nexiq software, they will become a brick.

Which one would you recommend wifi or bluetooth?

Both will work off bluetooth but I find bluetooth very slow. It’s faster and easier just to use a cable to connect to the laptop. The cable is a standard USB “printer” cable. I like using a 5 meter cable so I can move the laptop out of the truck is I have to. There are times I’ve used the laptop on the other side of the truck and even under the truck. The long cable makes it easier. Occasionally, I’ll use bluetooth.

I have no idea what the wifi option is. To me, that would mean if the Nexiq is communicating to the laptop over wifi then the laptop’s network connection isn’t connected to a router. Just ignore any wifi options.

How can you tell original from clone, is clone called differently?

The Heavy Duty Diagnostic Tool Nexiq 2 clones don’t have 26 pin cables just the standard fitting also the usb connector is different and there is a hole by the usb connector on the clones as well.
