I need help on 7C deliverables. The questions are on the final pictures.
Thanks!
HANDS-ON ACTIVITY 7C Wardriving and Warwalkin Wireless LANS are often not secure. It is simple to bring your laptop computer into a public area and listen for wireless networks. This is called wardriving (if you are in a car) or warwalking (if you're walking). As long as you do not attempt to use any networks without autho- rization, wardriving and warwalking are quite legal. There are many good software tools available for wardriving My favorites are Net Surveyor (available from http:// nutsaboutnets.cometsurveyor-wifi-scanner) or wire- less NetView (available from http://download.cnet.com/ WirelessNetView/3000-2162_4-191039.html). Both are simple to use, yet powerf WLAN (the ssid). The second column shows the last signal strength it detected, whereas the third column shows the average signal strength. I used NetView from my parked car on the street, so the signal strengths are not strong, and because I wasn't moving, the average signal strength and the last signal strength are the same. You can examine the PHY Types" column and see that most APs are 802.11n, although there are three older 802.11g APs. Values in the Maximum Speed" column are quite variable. There are some newer 8011.n APs that are running at the top speed of 450 Mbps. Some 802.11n APs provide 144 Mbps, which suggests that these WLANs are ul. The first step is to download and install the software likely to be older APs that are not capable of the higher on a laptop computer that has wireless capability.
