Input:
I purchased this item after I researched the different kind of routers available on the market. I think I made a very good choice. The only problem I had was related to my DSL provider (Earthlink) and they did not appear to be very helpful to me. Nevertheless, LynkSys provided me with the missing information and my router works just great.
