Or you can generate the 64-bit WEP key automatically:

■

enter a memorable passphrase in the

Passphrase

field, and then

click

Generate

to generate the hex keys from the passphrase.

For 64-bit WEP, you can enter up to four keys, in the fields

to

Key 4

.

The radio button on the left hand side selects the key that is used in

transmitting data.

Note that all four WEP keys on each device in the 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. Note that 3Com

recommends using WPA/WPA2 to secure your wireless connection.

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. For home network or very

small business networking environment, PSK is typically used.

Figure 44

WPA-PSK (no server) Screen

1

Select WPA-PSK (no server) from the

WPA

drop-down menu.

2

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”.

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.

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

of asterisks (*), then check the

WPA (with RADIUS Server)

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

constitutes the best security solution. This function requires that a

RADIUS server is running on the network.

WPS

Wi-Fi Protected Setup (WPS) integrate the new WLAN clients into your

wireless network easily. You can enable this function by entering the PIN

code via the web UI page or by pressing the WPS button on the rear side

of the device.
