I've used this product for more than a month, hoping to utilise its faster wifi specification being 802.11ac. Even though it can see my 5Ghz wireless AC access point channel with full bars, it fails to connect to it. I ended up using the 2.4 Ghz wireless N channel. I did not return the product because it works fine with lower wifi speed. However, after a month of using, my wireless connection gets dropping out. I thought it was a driver problem, but after re-installing the drivers, the wifi drop out still persists. I don't recommend this product!
