                          &gt; Hi guys,<br>
                          &gt;<br>
                          &gt; I thought you&#39;d like to know about this.
                           I heard the host on the Tech News<br>
                          &gt; Today podcast ( <a href="http://twit.tv/tnt" target="_blank">http://twit.tv/tnt</a>
                          ) say something similar to the following:<br>
                          &gt; Comcast will be expanding its wifi
                          network by putting wifi gateways in<br>
                          &gt; Xfinity users homes. ... Comcast users
                          will get free access. ... Guests get<br>
                          &gt; two free accesses. ... If you don&#39;t want
                          to participate, you have to opt<br>
                          &gt; out.<br>
                          &gt;<br>
                        </div>
                        &lt;snip&gt;<br>
                        <div>&gt;<br>
                          &gt; Supposedly, they replace your cable modem
                          with this new wifi gateway device.<br>
                          &gt; It broadcasts two wifi signals.  You log
                          into one of them and use YOUR<br>
                          &gt; service as normal.  Guests login into the
                          other, for free if they are<br>
                          &gt; Comcast Xfinity customers, and get two
                          free accesses if they&#39;re not Xfinity<br>
                          &gt; customers.  SUPPOSEDLY, the 2nd
                          connection is independent of the main one,<br>
                          &gt; and it doesn&#39;t reduce your bandwidth.
                           Yeah, I believe that.  The APPARENT<br>
                          &gt; plan is to replace all the gateways and
                          enable this internet sharing without<br>
                          &gt; the customer&#39;s knowledge.  That&#39;s got to
                          be against the law somehow.<br>
                          <br>
                        </div>
                        Don&#39;t see how it would be against the law.
                         They&#39;re going to replace a<br>
                        device they own connected to a service they own
                        with another device<br>
                        they own connected to a service they own?<br>
                        <div><br>
                          &gt; Now, I know some people willingly share
                          their wifi.  I&#39;m not one of them.  I<br>
                          &gt; have my wfi encrypted with long ugly
                          passwords.  There are 3 main reasons.<br>
                          &gt; 1) Any other user on my modem is a
                          potential security risk.<br>
                          <br>
                        </div>
                        I don&#39;t know how they have implemented this, but
                        it would be trivial<br>
                        to assign a 2nd public IP (or even NAT through a
                        single<br>
                        neighborhood-wifi-network IP) for the 2nd
                        hotspot and route all<br>
                        traffic over that.  In that case, a user
                        connected to that has the<br>
                        same amount of access as anyone else on the
                        internet.<br>
                        <div><br>
                          &gt; 2) It does<br>
                          &gt; reduce my bandwidth and performance.<br>
                          <br>
                        </div>
                        Citation needed.  The biggest limitation to your
                        bandwidth is the<br>
                        traffic shaping comcast performs at their head
                        end unit.  If the<br>
                        &quot;public&quot; hotspot is shaped separately, then I
                        don&#39;t see how it would<br>
                        impact your bandwidth.  *Maybe* you could make
                        an argument regarding<br>
                        wifi interference, but a 2nd hotspot on your
                        device won&#39;t be any<br>
                        different from a 2nd device somewhere nearby.<br>
                        <div><br>
                          &gt; 3)  If someone else does something<br>
                          &gt; illegal while connected to your wifi, the
                          police can ( and HAVE ) showed up<br>
                          &gt; at your door and arrest you.  You then
                          have to prove you didn&#39;t do it and<br>
                          &gt; it&#39;s a royal mess.<br>
                          <br>
                        </div>
                        Actually, no, the prosecution still has to prove
                        you did it (at least,<br>
                        legally), but yes, I suppose it could cause some
                        headaches, unless<br>
                        they can look at wifi hotspot vs private
                        network.  Not sure how that<br>
                        would work.<br>
                        <div><br>
                          &gt; Regardless, no ISP should be able to
                          enable this type of access without the<br>
                          &gt; user&#39;s knowledge and consent.<br>
                          <br>
                        </div>
                        On this, I agree.  This should be with the
                        user&#39;s consent, but I don&#39;t<br>
                        see it as a big bad threat.<br>
