User's Manual

Wireless-G Router User's Manual

• WEP (Wired Equivalent Privacy) is the least secure option, but is supported by all

Wireless-B and Wireless-G clients. One reason it is relatively insecure is that it

does not automatically change keys.

• RADIUS (Remote Authentication Dial-in User Service) can be used together with

WEP to provide authentication and periodically change keys. This requires a

RADIUS server, which can be expensive and difficult to administer.

• WPA Personal is Wi-Fi Protected Access–Personal, also known as WPA-PSK

(WPA Pre-shared Key). This uses the Temporal Key Integrity Protocol (TKIP) to

periodically change keys. Newer WPA Personal clients can use AES (see next).

• WPA2 Personal uses the more powerful Advanced Encryption Standard (AES),

and can also use AES and TKIP concurrently so that both WPA2 Personal and

older WPA Personal clients can connect.

• WPA Enterprise is similar to WPA Personal but adds RADIUS authentication,

requiring a RADIUS server.

• WPA2 Enterprise is similar to WPA2 Personal but adds RADIUS authentication,

requiring a RADIUS server.

Setting the Encryption Option: Check your wireless clients to find the most secure

encryption option they can all use (keeping in mind whether or not a RADIUS server

is available). Then click the Wireless page's Wireless Security tab, open the

Security Mode list, and select the option you will use.

Controls for setting up the selected encryption method will appear. Follow the

instructions below for that method.

• WPA Personal Step 1; WPA Enterprise Step 1:

Check, and if necessary change, the WPA Algorithms setting.

Leave this control set to TKIP if you have clients that can only use TKIP. Set this

control to AES if all your clients can use AES and you want stronger encryption.

• WPA2 Personal Step 1; WPA2 Enterprise Step 1:

Check, and if necessary change, the WPA Algorithms setting.

If only WPA2 clients will connect, use AES. If both WPA2 and WPA clients will

connect, use TKIP+AES.

• WPA Personal Step 2; WPA2 Personal Step 2:

(a) Input the WPA shared key.
