I'm getting pretty frequent disconnects with this adapter despite a very strong wireless AC signal. I'll be happily surfing and then see the yellow triangle on the wireless icon in my taskbar and I'll lose internet. Happens about once a day. Only unplugging the thing and plugging it back in resolves it. I've downloaded the latest drivers and tried all 5GHz channels. Unacceptable considering I'm 20 feet from the router with no walls blocking things. I'll try disabling beam forming and if that doesn't resolve it I'll send both the adaptor and my new Asus laptop back and get another model with an internal wireless AC card in it. Probably should have done this in the first place but Asus put cheap wifi cards in all but their high end laptops and I was hesitant to buy an alternate brand laptop.
