bought this twice and both kept on disconnecting for a couple seconds which is really annoying especially if you're a gamer. why in the world is Dlink still selling this stuff in the market is beyond my comprehension. I mean it's just unethical, they're practically ripping our wallets off man. I bought this product thinking it was cheap and I ended up buying it more than once... *sigh* I don't know about the other D-link products, but this one is one product you should never buy regardless of the price. I hope you're reading this post before you decide to buy the USB adapter. I've tried rev C(1st) and A1(2nd). I called the tech support and they weren't generous enough to give you replacement if you don't have the warranty card. heck it's not even about generousity anymore. I'm posting this topic, as a consumer, with good intention, please don't support this product by not buying them. seriously.... look at the rest of the topics, they're all talking about problems with this device, that should ring a bell.
