Side note. Please don't rent your modem / router through Comcast or any other ISP. They are so cheap now. If the ISP is charging even $5 / month, (I think it's more now but back when I bought mine, I believe that's what they were charging) that's $60 / year. A modem is $50 for a decent DOCSIS 3.0 that supports gig speed. Routers are not that expensive either, and very easy to set up. If you buy the hardware, it's a one time expense. The rentals you are paying for in perpetuity.
