L2TP mode
The Layer Two Tunneling Protocol (L2TP) provides a standard method for 
transporting the link layer of the Point-to-Point Protocol (PPP) between a 
dial-up server and a Network Access Server, using a network connection 
in lieu of a physical point-to-point connection. This mode is most often 
used in Israel. To set up the Router for use with a L2TP (Layer 2 Tunneling 
Protocol) connection, use the following procedure:

Wireless Security: 64-bit WEP 
WEP is the basic mechanism to transmit your data securely over the 
wireless network. Matching encryption keys must be setup on your 
Router and wireless client devices to use WEP. 3Com recommends to use 
stronger WPA/WPA2 security. 
Figure 31   64-bit WEP Screen 
To enable 64-bit WEP: 
1You can enter the 64-bit WEP key manually. Enter the WEP key as 5 pairs 
of hex digits (0-9, A-F). Or you can generate the 64-bit WEP key 
automatically. Enter a memorable passphrase in the Passphrase box, 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 Key 1 to Key 4. 
The radio button on the left hand side selects the key that is used in 
transmitting data.
2Click Apply.
Note that all four WEP keys on each device in the wireless network must 
be identical. 
						

							46CHAPTER 4: RUNNING THE SETUP WIZARD
Wireless Security: 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. 3Com recommends to use 
stronger WPA/WPA2 security. 
Figure 32   128-bit WEP Screen 
To enable 128-bit WEP: 
1You 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.
2Click Apply.
Note that the WEP keys on each device on the wireless network must be 
identical. In 128-bit WEP mode, only one WEP key can be specified.

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.
Figure 33   WPA-PSK (no server) Screen 
11 Select WPA-PSK (no server) from the WPA drop-down menu.
2Select WPA mode from the drop-down menu, three modes are 
supported: WPA, WPA2, and Mixed mode.
3Select 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”.
4Enter 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.
5If you want the key that you enter to be shown on the screen as a series 
of asterisks (*), then check the Hide PSK checkbox.
6Click Next.

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.
Figure 34   WPA with Radius server Screen 
1Select WPA with RADIUS server from the Security Mode drop-down 
menu.
2Select WPA mode from the drop-down menu, three modes are 
supported: WPA, WPA2, and Mixed mode.

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”.
4Enter the IP address of the RADIUS server on your network into the 
RADIUS Server field.
5Enter the port number that the RADIUS server is operating on in the 
RADIUS Port field.
6Enter the key for the RADIUS server in the RADIUS Key field.
7By default, the WPA keys are changed every hour, but if you want to 
change this setting, you can do so by specifying the required time in the 
Re-key Interval field.
