Well said, Jan. Duane, you will want to look for a 3rd party "Comcast-certified" modem (Arris is a popular brand). Also purchase the N-wireless router that has a guest network option (most do). When replacing yours, it will have a sheet inside to walk you through the activation process. It takes 5 minutes if it proceeds automatically or about 30 minutes if you have to talk to a Comcast rep. Get the info for sending theirs back, and also check your next bill to make sure you're no longer being billed for it. -- *Zach Fried* *Local Prosperity Partners, LLC* *Technology* <http://localprosper.com/services/mac-pc-support-repair/>* • * *Design* <http://localprosper.com/services/design/>* • **Skills* <http://localprosper.com/services/skills-training/>* • **Strategy* <http://localprosper.com/why/> PO Box 1232 Amherst, MA 01004 zach at localprosper.com Office: (413) 461-0617 On Sun, Jan 10, 2016 at 9:15 AM, Jan Werner <jwerner at jwdp.com> wrote: > > > > Don't use the Comcast box as a router! > > Most third part wireless routers will give you far better coverage than > a combined modem/router and many of them allow you to set up one or more > guest networks that are isolated from your main network. > > You are probably paying a fee to Comcast to lease their modem/router box > which you could amortize in a year or two by buying your own cable modem > (You can find lists of those that Comcast supports on their website) and > your own router. > > Furthermore, Comcast's own routers are designed to let them be used as > open access WiFI hotspots - if you ever wondered about how Comcast and > Time Warner can offer thousands of free WiFi access points nationwide, > that's how.
