I have purchased tenda d151 wifi router plus modem almost one year ago. It is a good product from tenda company. It has convenient features. It is a router+ modem so I dont have to buy a separate modem. It has good wifi coverage.i have installed it in my house for me and my family. It has IPVC feature also. Although it is a one antenna router but it has good area coverage. It has 4 lan ports and also features USB port. It is a good router+ modem for home usage and I am recommending this product.
