Oops, I think I phrased my question incorrectly.
Does this USB device work as a wi-fi receiver, like a Netgear AC600? I don't want to broadcast a signal, but just to use the oncoming signal from my main wi-fi router and provide an internet connection to my PC.
Ah no, since Netgear AC600 is a peripheral for connecting to WIFI access points.
But you can attach the Huawei E3372h to your computer via USB with SIM card on it to connect to the internet, so if you only have one device you need to use the sim card with, this will work.
