The results include SSID, MAC address, network rate (Speed) ,network access type (Type) , and whether there is WEP encryption(Encryption) and so on. With the "Speed" one, we can see thehotspot' s wireless access bandwidth. At this point, we onlyneed to access their own wireless network card to theappropriate AP, you can start surf ing the internet. It is worthmentioning that, NetStumbler can display the hidden SSIDwireless AP, in the software interface, you can see that theAP green light is flashing.

Tips:

Decoding AiroPeek support for different length of the WEPencrypted data stream, by renaming key to air decoding,contains a convenient command line to capture the encryptedpackage file is decoded, so even if the use of wireless signalWEP encryption is still unable to escape the "finger heartAiroPeek".

Http://www1.anywlan.com/Soft/ShowSoft.asp? SoftID=165download and run AiroPeek, you can see all the nodes in thewireless network IP address, packet statistics, networktopology display AiroPeek in a schematic form, is veryintuitive to let you know the structure of the network. Thepacket contains a variety of information sources, in additionto see (Source) and the target (Destination) address, protocol(Protocol) can make us all with 802. 11 related data packets tosee after sorting, if necessary can also further to analyze thecontents of the packet
