Home Forums Networks & Cross-Platform Networking Getting rid of a wireless network?

I have an old wireless network that shows up when both the router and the modem are off. It is left from before I installed the new hard drive, etc, and has something to do with Time Warner turning on the wireless part of the modem I have from them that I don't use. I had them turn the wireless part off, but it 'lives' somewhere in my mac and the router is not working right as long as it is there.

I have tried deleting it from the Network Control Panel, and pulling a lot of prefs, but I don't know where it is coming from.
