“Will this be just right for my needs? I am planning to switch from AT&T to Cox. The Cox package, however, does not include a wireless router but offered us the option to either buy our own router or buy/rent one of their own. The AT&T router we have since 2008 is a 2Wire Gateway 3800HGV-B. Will the N600 be equal, if not, better perform the 2Wire Router? My house is 3 stories high (condo-type) and we have an HD TV and 2 WiFi laptops. I just need fast download wireless internet speed and strong WiFi signal. It's my feeling that I might overpay for getting the N750 but since I am no techgeek, I am unable to do a comparison between the 2Wire and the N600. Thanks.”
