One of the configuration parameters transmitted to each network device is its default gateway.
This address is configured by the network administrators and it informs each personal computer
or other network device where to send data if the target station does not reside on the same
subnet as the source. If your machine can reach all stations on the same subnet (usually a
building or a sector within a building), but cannot communicate outside of this area, it is usually
because of an incorrectly configured default gateway.
What is SSID ?
A service set identifier (SSID) is a sequence of characters that uniquely names a wireless local

independent networks operate in the same physical area
What is WEP ?
