    It's DOCIS 3.0 so it can handle fast network speeds which older routers can't. The set up easy and the price is affordable. I use it for streaming music and HD movies.

    Overall, if you don't mind the price, this modem works as advertised. The wireless version and wired version look identical, make sure you get a router with this model.
