Nighthawk AX4 Range

I also have an R6300 ac router and am looking to upgrade in the near future.

I had the same question about ax adapter availability timeframes, and after some research found that Intel actually recently released the AX200 M.2 card which you can actually buy right now.

I have a pc 2 floors up from my router which has a low signal connection to my router so i decided to buy an AX200 card to see if it alone would help make the connection to my existing R6300 router stronger.

After installing it, I now get almost twice as strong of a connection as before and obviously faster speeds.  (went from an unstable 40Mbps to a stable 85Mbps)  So it was definitely worth it for me, especially with the cost under $50.

I'll be upgrading to a Netgear AX router soon which will hopefully make the connection even stronger.

The AX200 M.2 comes as an M.2 card.

If you're installing it into a laptop with an existing M.2 network card it should work as is.

If you're installing it into a desktop you'll need to get a PCIe adapter to plug the AX200 card into and then install the PCIe into an empty PCIe 1x or greater slot.

I installed into a desktop so i needed the converter.  Below are links to the 2 items i bought.

It installed easily without any issues.
