Xfinity Speed Slower When I Connect to my Own Routers than to My Neighbors Modem/Router

[sms]

I have a standalone DOCSIS modem and two 802.11N wireless routers. My
neighbor has Xfinity's modem/router with the open wi-fi second channel
for any Xfinity user.

I get much faster speeds (17Mb/s) when connected to his modem/router
than when I connect to my own router (10-12 Mb/s). And the second
channel is supposed to be slower than the main channel.

Anybody with any class of Comcast internet service gets a login which can be
used with any "xfinitywifi" SSID signal. So, even with the slowest Comcast
service a user can get fairly fast service using an xfinitywifi signal.
Most of the ones I use serve at least 20Mbps, and some serve 30, though it
probably depends on what the user is using on their own slice of the
bandwidth.

No. The XfinityWifi has its own channels on the cable.
There is no impact on the subscribers bandwidth.

The pipe is only so wide, so the overall speed is still going to depend on
how many users are connected after the local Comcast point of presence.
Remember seeing the TV ads where the neighbors are going out into the
streets complaining about a neighbor hogging all the bandwidth? It was an
ad for AT&T...

:-) The best lie is a truth. For those that don't know, cable is
faster than DSL, was then, was way back then, and is still true today.
Not going to be much different tomorrow, unless AT&T installs GPON or
something that competes. I'm skeptical that radio will ever be nice
enough and cheap for me to like it. 140/12.

The Xfinity Cable is divided into several channels. Channels are bonded
together in your modem to give you various speeds on the connection.
Some of the channels are not available for you to use, depending on your
equipment, and the subscription you have with Comcast.
There are channels dedicated to XfinityWifi that will never be part of your
allocated channels, hence not part of your allocated bandwidth.

That was an ad referring to oversubscribed head ends. The cable companies
used to be very slow adding more service to a trunk when slowdowns
occurred. They are much more responsive and even proactive, now. The days
of cable slowing down in the evenings are long behind us.
