The Rayswitch 300Mbps Wireless N Range Extender NREW1L is designed to establish a highly efficient mobile office or entertainment network with wider coverage. NREW1L works as a "Range Extender" in default, which will pick up the wireless signal from your main router and expand it to somewhere that your main router may not reach. Also,  NREW1L can support Router mode to setup a secured internal network from a DSL or cable modem. With portable design, it's a perfect choice for travelers, students, or anyone else for work or play.
