Hey Gang,How do the cable companies generally deliver this service? A friend insists it piggybacks off the WIFI radios of existing cable company subscribers. In other words, the cable company WIFI router in a flat is providing both a private link for the flat's subscriber, but also a public hotspot service.
That's pretty much it. The cable provider typically provides a multi-function box that's a cable modem, NAT router, analog telephone adapter, and wi-fi hotspot. In addition to the SSID for individual customer use they by default have a generic SSID that is used by any roaming Comcast customer within range. This has a nasty habit of landing on the same channel as other devices and causing interference. The user interface doesn't show this or have any way of disabling it.
They provided one of these for my sister and of course their box wasn't exactly in the best place in the house for radio. I put in a proper access point and it took several phone calls to tech support to get them to turn off the radio in their box completely including the default roaming SSID. I was this >< close to opening the thing up to figure out which trace to cut when I finally got someone with enough clue to turn it off.
