I havent experimented with it as of yet, but xfinity did note that those customers that have these routers do not get any additional bandwidth nor "supposedly" it takes any away from them. I am not sure how they manage the connection so it might be something worth exploring. My true consern was that there are many dummy xfinitywifi hotspots out there and you cant tell the real one from fakes apart. Since only xfinity customers are able to use their home logins to use these hotspots a dummy xfinitywifi hotspot could become a very easy collection site for all the xfinity users login information gathering. So potentially you could get hundreds of thousands of logins and be able to login under those credentials to a real xfinitywifi hotspot which are located all over the place. and with this comcast time warner merger 2/3 of the united states will have those hotspots active.. 2/3 of the country! thats like having access to someones cellphone use at any given time...
