Interesting, I may need to open a ticket with Moto to ask how that’s done.

>From talking to folks involved with http://www.cablewifi.com/ and Comcast support there is a separate service flow for the public SSID.  I have yet to configure that in the lab, but it sounds like a good project :)

It's my understanding that the public Wi-Fi uses the same data flow as the subcriber's data flow.  I've seen nothing in the release notes for ARRIS or Moto that suggest one can tie an SSID to a specific service flow.

I expect Frank Bulk to have an opinion on this, all others welcome.

Hat tip to Bright House -- I've noticed lately that I don't have to go
through their captive portal when using their public wifi hotspots (they
participate in the CableWifi consortium, using WAPs built into their
6580 and other cablemodems, and offer a carrier-specific connection SSID
as well).

This has led me to a point of curiosity:

If I'm the subscriber, and I've paid for 15 mb/s down, then my wired
connection and my private wireless (if provisioned, and they charge
$10/mo, so I'll do that myself, thanks) are using one ... DOCSIS path?
back to the CMTS.

I assume that cableco provided voice is on a separate path, and I'm sure
the TV service is -- if it's even IP at all.

But the question is: is that public wifi service *also* on a separate
bandwidth-limited channel out of the cablemodem?

Offline replies fine, unless you think it's of sufficiently general
interest; I expect it's implementation dependent.
