[ale] heads up - warning - you could be sharing comcast wifi without knowing it

[Lightner, Jeff]

I don’t see the original in this thread.

Is Comcast putting wireless routers in homes and making them publically available?

I was pondering the possibility of the cable modem taking shortcuts or having bugs that would route the guest wifi into my home subnet erroneously.  If, as has been mentioned, the nets are fully separate until they hit the CMTS, then it's not an issue.

How would they do that?  Do you not have a firewall for your machines?
The way I understand this is that the "public wifi" portion would be on
a different network than your "personal" connection, so anyone on the
public side would have the same access to your network as someone
anywhere else on the Internet.
