This product only contains drivers up to and including Windows XP. Packaging clearly states 'Supports all major OS's'. This may have been true 10 years ago but not today. Will be returning this product.
I've used Tenda products before (various Wi-Fi routers) and have always been impressed. This is no different. Works as it should, for a great price. Got mine to replace the failed on-board NIC (realtek) in my wife's PC.
