I have a ASUS S56CA-DH51 with an Atheros N card. I want, and need, a Dual Band a/c adapter. ASUS will not give me any recommendations, Literally said they cannot comment. Why they would want to put me through this run-around is beyond me! So, yea, Google, so far? Nothing. Perhaps I don't know how to narrow it down. I want to know what WILL work in my laptop. I went through an agonizing nightmare, a few years ago, trying to update my brother's wifi card in his Acer. I was hoping that I could avoid that by contacting ASUS. No go. Anybody here have any advice? I cannot afford to be opening this thing up a bunch of times and buying and returning parts. Thanks, in advance for the endless help I am sure to find here on the World's best website!! I would like to avoid having to use a USB adapter. I have enough stuff to lug around and try not to break!!
