I just talked to BestBuy Geek Squad and they suggested a Motorola SurfBoard (there are no waves in my house) modem # SB5101U and a NetGear N300 router. Opinions?
No. Get the sb6121, its a docsis 3.0 modem and you'll get better speeds. And if you have a big house and need good wireless then get this router.
