If I could have given the ASUS support and service website a zero, I would have. It is written entirely in jargon and abbreviations that are essentially a wall to anyone who is not technically inclined. Just entering the serial number was impossible because it is in micro print and it is very difficult to discriminate o from 0, and 1 from i, and so on. I could not find a way to get into the website because it would not accept what I thought was the right serial number. Two of the buttons did not work. when I tried to go backward it threw me out of the program where I had to download their app again. After 55 minutes I had not been able to even sign in. Nothing from ASUS works... not the modem and not the website. Do not buy anything from ASUS!
