Many of you have probably experienced the frustration of being out of range of a wireless signal when you need one. Even though hot spots are growing at a rapid pace, you aren't always within range of one that you can log onto for free.
In the video below, Mark Erickson, who creates video podcasts called Infinite Solutions, shows you a hack to extend the range of your wireless card. Although it is disappointing that he doesn't put the tin foil dish on his head, this is still an interesting solution.
And here's a video on a software product called Easy WiFi Radar that helps you easily detect wireless networks that are within range. The software also sees if it can log you into the networks that it detects.
However, you should exercise extreme caution when searching for wireless networks. Just because you can detect a network and log onto it, doesn't mean that you are legally entitled to do so. You could be guilty of violating "piggybacking" laws. Piggybacking is using someone's bandwidth without their permission. So I recommend sticking to hot spots that are free where merchants are encouraging you to log on (such as Panera Bread). Web sites like WiFinder can help you locate hot spots that you may access legally.
Discussion Questions for Students:
1) Have you ever logged onto a wireless network without the owner's permission (such as a neighbor)? What do you think the implications would be if you get caught engaging in this type of activity?
2) Is it illegal where you live to "piggyback" on a wireless signal? Do you feel it should be illegal to connect to an unsecured wireless network without the owner's permission?
3) Where can you go locally to legally connect to a wireless network and get free Internet access? What types of benefits do merchants like Panera Bread derive from providing free wireless access to their customers?
4) If you aren't a customer of Panera Bread, do you think it is fair to sit outside in your car and connect to their wireless network?
