Last night my home internet went down for unknown reasons. During that time, I tethered my cell phone to my computer using a USB cable and an android tethering software that I previously bought as a back up. That's when I posted the question. Later, the home internet worked again for unknown reasons. So I hope I won't be needing the tethering method in the future, though I think 4G LTE in my area keep up with 4MB/minute. I didn't test speeds since I have pay as you go data, since I usually have phone data off.
