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. 

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.

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.
