"Security. You are solely responsible for the security of any device connected to the Service, including any data stored on that device. Cox recommends that you take appropriate security precautions for any systems connected to the Service. You are responsible for securing any wireless (WiFi) networks connected to your Cox service. Any wireless network installed by the customer or a Cox representative, that is unsecured or "open" and connected to the Cox network, will be deemed to be operating as an ISP and subject to the prohibition on Commercial Use set forth in Section 5 herein. You authorize Cox to use measures to detect unsecured wireless networks associated with your Service."
From the looks of it, Cox says that you have to secure your own router or they can come along and tag you as a commercial connection and pay for bandwith like that.
So it looks like according to Cox (and most other ISP I am sure) haveing an open wireless connection is against the rules and can possiable get you charged!
That still doen't change the fact that I belive there is nothing wrong with shareing the wealth that you have with other less fourtinate folks. If you got it and others dont, it does not take hardly anything for you to help a broke neighbor out!...lol
Thats my 2 cents no one ask for!
