ZyXEL P-336M User's Guide Table 11 Basic: Wireless: Basic WIreless LAN Setup (continued) LABEL DESCRIPTION Channel The radio frequency used by IEEE 802.11 wireless devices is called a channel. Select a channel from the drop-down list box. Transmission Rate Select a transmission speed from the drop-down list box. 802.11 Mode SuperGTM Mode Select 802.11b only to have the P-336M connect to an IEEE 802.11b wireless device only and vice versa. Select Mixed 802.11b and 802.11g to have the P-336M connect to either an IEEE 802.11g or IEEE 802.11b wireless device. Select 802.11g only to have the P-336M connect to an IEEE 802.11g wireless device only and vice versa. Select the check box to have the P-336M transmit at up to 108 Mbps when connected to an AP or wireless router with the SuperG feature enabled. 3.7 Wireless LAN Security Overview Wireless LAN security is vital to your network to protect wireless communications. Configure the wireless LAN security using the Wireless screen. If you do not enable any wireless security on your P-336M, the P-336M's wireless communications are accessible to any wireless networking device that is in the coverage area. 3.7.1 WEP WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the P-336M and 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 P-336M. • 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. • Enter the WEP keys manually. Your P-336M 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. 3.7.1.1 Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP.

Wireless LAN Security Overview
Wireless LAN security is vital to your network to protect wireless communications.
Configure the wireless LAN security using the
Wireless
screen. If you do not enable any
wireless security on your P-336M, the P-336M’s wireless communications are accessible to
any wireless networking device that is in the coverage area.
3.7.1
WEP
WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between
the P-336M and 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 P-336M.
•
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.
•
Enter the WEP keys manually.
Your P-336M 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.
3.7.1.1
Authentication Type
The IEEE 802.11b/g standard describes a simple authentication method between the wireless
stations and AP. Three authentication modes are defined:
Open
and
Shared Key
.
Channel
The radio frequency used by IEEE 802.11 wireless devices is called a channel.
Select a channel from the drop-down list box.
Transmission Rate
Select a transmission speed from the drop-down list box.
802.11 Mode
Select
802.11b only
to have the P-336M connect to an IEEE 802.11b wireless
device only and vice versa.
Select
Mixed 802.11b and 802.11g
to have the P-336M connect to either an IEEE
802.11g or IEEE 802.11b wireless device.
Select
802.11g only
to have the P-336M connect to an IEEE 802.11g wireless
device only and vice versa.
SuperG
TM
Mode
Select the check box to have the P-336M transmit at up to 108 Mbps when
connected to an AP or wireless router with the SuperG
feature enabled.
