Wireless internet validating identity problem

WPA2 uses an encryption device that encrypts the network with a 256-bit key; the longer key length improves security over WEP.

Enterprises often enforce security using a certificate-based system to authenticate the connecting device, following the standard 802.1X.

The most common type is Wi-Fi security, which includes Wired Equivalent Privacy (WEP) and Wi-Fi Protected Access (WPA).

WEP is a notoriously weak security standard which was superseded in 2003 by WPA, or Wi-Fi Protected Access.

The current standard is WPA2; some hardware cannot support WPA2 without firmware upgrade or replacement.

If router security is not activated or if the owner deactivates it for convenience, it creates a free hotspot.

Since most 21st-century laptop PCs have wireless networking built in (see Intel "Centrino" technology), they don't need a third-party adapter such as a PCMCIA Card or USB dongle.

Built-in wireless networking might be enabled by default, without the owner realizing it, thus broadcasting the laptop's accessibility to any computer nearby.

Modern operating systems such as Linux, mac OS, or Microsoft Windows make it fairly easy to set up a PC as a wireless LAN "base station" using Internet Connection Sharing, thus allowing all the PCs in the home to access the Internet through the "base" PC.
