Note that all four WEP keys on each device of the same wireless network

must be identical.

128-bit WEP

WEP is the basic mechanism to transmit your data securely over the

wireless network. Matching encryption keys must be set up on your

Router and wireless client devices to use WEP.

Figure 36

128-bit WEP

To enable 128-bit WEP:

1

You can enter the 128-bit WEP key manually, enter your WEP key as 13

pairs of hex digits (0-9, A-F). Or you can generate the 128-bit WEP key

automatically, enter a memorable passphrase in the Passphrase box, and

then click

Generate

to generate the hex keys from the passphrase.

Note that the WEP keys on each device of the same wireless network

must be identical. And In 128-bit WEP mode, only one WEP key can be

WPA-PSK (no server)

WPA (Wi-Fi Protected Access) provides dynamic key changes and

constitutes the best security solution. If your network does not have a

RADIUS server. Select the no server option. Note that in home and very

small office deployments, PSK is typically used.

Select

WPA-PSK (no server)

from the

WPA

drop-down menu.

Select

WPA mode

from the drop-down menu, three modes are

supported: WPA, WPA2, and Mixed mode.

3

Select

Encryption technique

from the drop-down menu, four options are

available: TKIP, AES, Auto for WPA AES for WPA2, and AES for both WPA

and WPA2.

WPA supports TKIP and AES Encryption technique, for some old module

of wireless client cards, they may only support TKIP. In this case, we

suggest you to select “AUTO for WPA, AES for WPA2”. If your wireless

client cards can support AES over WPA, we suggest you directly select

“AES for both WPA and WPA2”.

4

Enter the pre-shared key in the

Pre-shared Key (PSK)

field. The pre-shared

key is a password, in the form of a word, phrase or series of letters and

numbers. The key must be between 8 and 63 characters long and can

include spaces and symbols. Each client that connects to the network

must use the same key.

5

If you want the key that you enter to be shown on the screen as a series

of asterisks (*), then check the
