Chapter 3 Wireless LAN Network

•Every device in the same wireless network must use security compatible with the AP or peer computer.

Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.

3.2Wireless LAN Security

Wireless LAN security is vital to your network to protect wireless communications.

Configure the wireless LAN security using the Security Setting screen. If you do not enable any wireless security on your G-210H, the G-210H’s wireless communications are accessible to any wireless networking device that is in the coverage area.

"You can only use WEP or WPA-NONE if you set the G-210H to Ad-hoc mode.

See the appendices for more detailed information about wireless security.

3.2.1User Authentication and Encryption

You can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.

Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.

3.2.1.1 WEP

3.2.1.1.1 Data Encryption

WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the G-210H and the AP or other wireless stations to keep network communications private. Both the wireless stations and the access points must use the same WEP key for data encryption and decryption.

Your G-210H allows you to configure up to four 64-bit or 128-bit WEP keys and only one key is used as the default key at any one time.

3.2.1.1.2 Authentication Method

The IEEE 802.11 b/g standard describes a simple authentication method between the wireless stations and AP or peer computer. The authentication types are defined: Open system and Shared key.
