Answer for I have 150 mbps speed plugged direct from moden and want to buy router to operate wireless. What should I buy?

I generally recommend a router similar to a Linksys EA3500 to start with. With gigabit Ethernet ports, that router and similar models from other brands can definitely handle a 150 Mbps Internet connection. Of course, other factors, such as what wireless devices you will be using and how big of an area you are trying to cover, can impact the real-world speed of your connection once all is said and done.
