TWC WiFi is shared with US. Bright House Networks, Cablevision, Comcast, and Cox Communications as CableWiFi. If you have an account with any of them you can use their independent WiFi systems or use the CableWiFi id. Once you register your device with your ISP, it will automatically be recognized by all the systems without the need to log in.
