Should i buy tp-link 150 mbps wireless n router or tp-link 300 mbps wireless n router? Is it necessary that wireless router must be connected by a modem? Or is it better to have a wireless router cum modem?
300 mbps routers generally have 2 antennas which support 150 mbps each. The basic difference is in the speed and range of the wifi network that you will get. If you are a user who will not be using the router for high bandwidth intensive tasks (read gigabytes of data transfer etc) and do not live in a very big house (read mansion) the tp-link 150 will work well for you. If however, your home has many walls separating the living rooms or is very big and many users are going to use the network, then its better to go for the 300mbps router.
I am a single user at my place and the 150mbps works very well for me. Besides, the TP-link 150 has a very good review. Also, among the 150 mbps routers, its got the best throughput (read range).
