All right, I've never had WiFi before and have no idea how it works so I had some questions about trying to get WiFi in my house. I don't post in any other forums and figured this would be the best place to ask. So, I currently have a cable internet connection. Now, in order to get wireless internet, would all I need to do is buy a wireless router and hook that up to my cable box thingy (yeah, I know, I'm not familiar with my techie jargon). Then it'll transmit my internet wirelessly throughout my house/where have you? Or would I need to cancel my current cable internet and set up a new connection with my current internet service provider that is WiFi capable and get new box thingys to receive wireless internet? :\ I have an iMac, a PC, and an iPhone 3G and it'd make my life a lot easier if I could get wireless internet. Any help is MUCH appreciated!
