[ARS] Comcast turns your Xfinity modem into public Wi-Fi hotspot - Page 2

post #11 of 63
It will only be available through their equipment. If you have your own modem, say a Cisco Dpc 3000, there is no built-in wifi so there is no router for them to access. Typical Comcast thinking...get our customers to pay for the equipment and bandwidth so that we can offer another "service"... It will not affect your bandwidth, though, as Docsis 3 has built-in load balancing and the simple fact that the prices that Comcast charges for top tiers guarantees that no one will ever overload the network! Most Comcast neighborhoods are 75% low end tiers so there is always plenty of bandwidth overhead now unless you live in a really heavily oper populated city node.

So just to clarify, if we only got a modem from them and then we bough our wifi router separatedly we should be fine right?

They will only be able to put their wifi signal out from a combo modem/wifi router that you rent from them.

comcast now offers and in some places pushes a router/modem in one . So they will likely try and make everyone use this modem/router combo of theres instead of a regular modem. I had the combo device when I live in dc ,but I don't think it did the sharing.

...no, they wouldn't. It's a separate network.

Imagine an apartment building with a bunch of these.

For 40MHz, you need two channels adjacent channels... this makes it harder to fine those.

Comcast has always had router/modem combos....

Thinking about it further, separate network, and no speed impact... I don't really see how anyone would have a basis to complain. Nobody is connecting to "your" network, or using "your" bandwidth.

I can see how channels could become a problem in apartment complexs... hopefully they have some sort of monitoring system for that and disable any overkill networking as opposed to blindly enabling it on every modem.

Since the networks are separate, customers don't have to worry about losing bandwidth to passersby, Comcast said.

"Our broadband customers will continue to get the service that they are paying for," Comcast Senior VP of Business Development Tom Nagel told CNET. "That was extremely important to us in designing this product."

ALWAYS ? Weird no such thing was available in my area for 7 years with comcast until I moved to DC. So always is a bit steep.
