It uses the 802.11AC WiFi-5 protocol and is a dual-band that works in the 2.4GHz or 5GHz frequencies.

The Inamax wireless USB 3.0 Adapter is a good fast low-cost unit.

It worked very well with Windows 10 along with some very good speed results.

The 5dBi antenna will help with range and be able to get a better signal.

I am still testing this adapter so far with good results and will update if anything changes.

As always be sure to read the review on Amazon or elsewhere to be sure a unit is a good fit for you.

    I recently downloaded and installed the latest Windows 10 version on my HP and discovered the AC1200 Inamax was not functioning. Deleted the old program/drivers, plugged it back in and it is once again working as it was – FAST!

    My laptop doesn’t have a cd-rom so I looked for a download of the driver CD. I didn’t have any success.
    I inserted the dongle/usb and it looks like the inamax ac1200 installed itself and is operating. I need to know if installing the driver cd would do anything important?

    So I have a 2011 MacBook Pro that apparently had problems wit its logic board when it first came out. The computer has worked fine up until now because the WiFi has suddenly stopped working. I brought it to a Mac outlet and they said that the WiFi card on the logic board had finally broken. Now when click WiFi from my computer it simply says “No hardware installed” (being that it no longer works). Would this USB WiFi adapter allow the WiFi on my computer to work once more? Or does it require that the WiFi hardware on my computer also work in order to work with this?

      I have a 2016 Macbook Pro, and tried this dongle. It struggles to connect, taking 5-10 minutes. Once connected, it’s very solid, but the slow connection time drove me crazy, so I don’t use it anymore. (Yes, I’ve tried downloading the latest Mac driver) –Rich
