What is wifi and how do you know if you have it? -- Posted by Molfsontan at 8:52 am on Aug. 23, 2008 You need a certain router that connects to your computer, otherwise you can look in your internet connections. -- Posted by King Kong at 8:52 am on Aug. 23, 2008 Do you have a rooter with your computer? -- Posted by psychotickid555 at 8:54 am on Aug. 23, 2008 if you have a wireless router and can still get internet without your cpu plugged in -- Posted by Tavis at 5:04 pm on Aug. 28, 2008 WiFi is, in my mind, wireless internet that connect games, computers, and everything's internet. Now, the biggest giveaway if you have WiFi is whether or not you have a wireless router. They are usually less the 75$, and connect to your modem, and send out wireless internet signals. On laptops, it will pick these signals up, and will give you a list of available ones. Some may be secure, "locked", and others not. Anyone can take the insecure ones, but you need a password for the secure ones. So, if you don't have one, you don't have WiFi internet. Now, if you have a Wii or other game system, it might also send out signals, but not internet. For some games, you can use your DS, and the Wii sends out the signals for the DS to pick up, but only specifically for the DS.
