Comcast To Expand Public WiFi Using Home Internet Connections 203

Bob the Super Hamste writes "The St. Paul Pioneer press is reporting that Comcast is planning on expanding its network of public WiFi hot spots in the Twin Cities area by using home internet connections and user's WiFi routers. Customers will be upgraded to new wireless routers that will have 2 wireless networks, one for the home users and one for the general public. Subscribers to Comcast's Xfinity service and customers that participate in the public WiFi program will be allowed free access to the public WiFi offered by this service. Non Comcast customers get 2 free sessions a month each lasting 1 hour with additional sessions costing money. The article mentions that a similar service already exists and is provided by the Spain-based company Fon."

    In the UK BT does this. Their customers can use any of the hotspots for free and everyone else has to pay, no free hour.
    • Same thing in Belgium with Telenet. Works quite well. You can close the extra channel if you want, but then they also revoke your access to other people's base stations. You only get access if you also provide access yourself. Which doesn't cost you anything except maybe a tiny bit of electricity.

      "Does no work for you?"

      Yes, "no" works for me, but for completely different reasons.

      I already do this, using my own cable adapter and my own router. And it is free for my neighbors and passersby to use. No charges from Comcast or anybody else. I do it as a free public service.

      And you have NO LEGAL LIABILITY for strangers using your Wi-Fi to perform illegal acts without your permission. Any more than an "internet cafe" does. People use it as they please, and they are responsible for their own actions. There have been many, many court cases over this by now.

      Think about it. If somebody came into your yard without explicit permission, grabbed your lawn de-thatching tool, and hit somebody over the head with it, would you be "liable" for murder? Hell, no. Nor are you liable, generally speaking, if you (legally) loan someone your gun and they shoot somebody with it. Unless of course you knew their intent ahead of time and loaned it to them specifically for doing that. But we're talking here about somebody doing something without your foreknowledge.

      So why should a router be any different? (Hint: it isn't.)

      By the way: the EFF recommends doing this [eff.org] as a courtesy to your neighbors and the public, and assures you that there is no liability.

      Again generally speaking, about the only time you are liable for someone's unauthorized use of your tools is when it is an automobile, and even that law is on pretty shaky legal ground.

      In a down-town area or any dense residential apartment situation a comcast user might find this appealing because they could roam all over the neighborhood and stay on wifi. But chances are, that is exactly the sort of situation where participation could cripple the homeowners use of their own connection.

      Service degradation. Those using the slower public portion of a home router typically won't degrade performance on the faster private side. Future routers would speed up public access when the private side isn't being used and give the private network priority if required.

It will be you spouse, child, roommate, etc. who will go to jail after the police haul all the computer equipment in your home away as evidence.

There are two benefits, the obvious being more widespread WiFi availability and those who openly want to share their network with neighbors (as a family member of mine does) can have increased security by locking their own network while still having the public one available.
