M-302 User’s Guide

32 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.

3.2 Wireless LAN Security

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

Configure the wireless LAN security using the Profile Security Settings screen. If you do not

enable any wireless security on your M-302, the M-302’s wireless communications are

accessible to any wireless networking device that is in the coverage area.See the appendices

for more detailed information about wireless security.

3.2.1 User Authentication and Encryption

User authentication is when every user must log in to the wireless network before they can use

it. 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 M-302 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.

There are two ways to create WEP keys in your M-302.

• Automatic WEP key generation based on a “password phrase” called a passphrase. The

passphrase is case sensitive. You must use the same passphrase for all WLAN adapters

with this feature in the same WLAN.

For WLAN adapters without the passphrase feature, you can still take advantage of this

feature by writing down the four automatically generated WEP keys from the Security

Settings screen of the ZyXEL utility and entering them manually as the WEP keys in the

other WLAN adapter(s).

• Enter the WEP keys manually.

Your M-302 allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys and

only one key is used as the default key at any one time.
