Wireless-N ADSL2+ Gateway

The QoS Tab

QoS (Quality of Service)

QoS ensures better service to high-priority types of network traffic, which may involve demanding, real-time

applications, such as Internet phone calls or videoconferencing.

Wireless

• ACK Mode. This setting prioritizes QoS for users who also have ACK Mode enabled. Users with Immediate

ACK (the default setting) will experience reliable connectivity for normal network use. Burst ACK is faster but

less reliable and may also affect long-range wireless performance. The No ACK setting disables the ACK

feature. Clients utilizing ACK must have their wireless adapter on the same setting as the Gateway. This is

normally used in a multicast broadcast like video. Do not use this unless you are an advanced user.

• 802.11e/QoS. QoS will be enabled by default to provide the best performance for your wireless connection.

Select Disable to improve performance for a mixed wireless network.

Internet Access Priority

In this section, you can set priority based on Application, Port Range, or MAC Address. There are four priories you

can set: High, Medium, Normal, or Low.

• Enabled/Disabled. To limit outgoing bandwidth for the QoS policies in use, select Enabled. Otherwise, select

Disabled.

• Set Internet Bandwidth. This setting allows you to limit the outgoing bandwidth for the QoS policies in use, so

you can control how much bandwidth a particular application is allowed to use. Enter the bandwidth in the

field.

• Application. With this option you can select None, Online Game, MSN Messenger, YAHOO Messenger,

Skype, Voice Device, Add a New Application, or select from the list of applications you want to set. To

create a new entry, select Add a New Application, and refer to the Add a New Application section.

• Priority. Select High, Medium, Normal, or Low for the bandwidth priority you need for the application you

selected. Don't set all applications to High, because this will defeat the purpose of allocating the available

bandwidth. If you want to select below normal bandwidth, select Low. Depending on the application, a few

attempts may be needed to set the appropriate bandwidth priority. Once you have made your selection, click

Add to add to the Summary list.
