I live on the upper two floors of a brownstone. The upper floor has a Lenovo W510 and a high speed cable modem. I'd like to link a flatscreen, wifi enabled, and an old Mac book on the lower floor. I've been advised to get an n dualband router. Any suggestions? Seems to be two camps: dlink and netgear. Am not terribly tech savvy on networking, however, I take direction well.
