Now I am going to tell about tenda wifi adapter which I use about since six months. Its really nice product, its signal strength is too good its capacity is upto 150mbps. I use it very frequently in my home and connect my mobile, laptop etc. its give smooth speed. This is nice device made by Shenzhen Tenda Technology Co. ltd. I watch videos on my laptop without buffering to its wifi connectivity, sometimes give slow speed cause of network fluctuation, but it works well.
