you want to use. If you plan to stream multimedia content or use VoIP on your network, the QoS feature
should be enabled.
ACK Mode
There are two acknowledgement (ACK) modes that can be employed to get the best multimedia
performance on your network: Burst ACK and Immediate ACK.
Immediate ACK is the default (factory) setting and is recommended for normal network operation. Changing
the ACK mode from Immediate ACK to Burst ACK may affect long-range throughput. Use Immediate ACK
when long-range performance of your network is most important to you.
Burst ACK mode will lower overhead by not acknowledging every packet sent over the network. When there
is a very good link between the Router and the client, Burst ACK can provide a throughput boost. If an
application, such as streaming multiple high-data video streams, requires maximum bandwidth, use Burst
ACK mode. Keep in mind that long-range performance may be affected when using Burst ACK mode.
QoS Switch
Allows you to turn ON or OFF QoS.
Changing the Wireless Security Settings
Your Router is equipped with the latest security standard called WPA (Wireless Protected
Access). It also supports the legacy security standard called WEP (Wired Equivalent Privacy). By
default, wireless security is disabled. To enable security, you will need to determine which
standard you want to use. To access the security settings, click “Security” on the “Wireless” tab.
Setting WPA Security
Note: To use WPA security, your wireless network cards must be equipped with software that
supports WPA. At the time this User Manual was published, a security patch from Microsoft is
available for free download. This patch woks only with Windows XP.
Your Router supports WPA-PSK (no server). WPA-PSK uses what is known as a pre-shared key
as the security key. A pre-shared key is basically a password that is between eight and 39
characters long. It can be a combination of letters, numbers, or characters. Each client uses the
same key to access the network. Typically this is the mode that will be used in a home
environment.
Setting WPA-PSK
1. From the “Security Mode” drop-down menu, select “WPA-PSK (no server)”.
2. For “Encryption Technique”, select “TKIP” or “AES”. This setting will have to be identical on
the clients that you set up.
3. Enter your pre-shared key. This can be from eight to 39 characters and can be letters,
numbers, or symbols. This same key must be used on all of the clients that you set up.
