To change the MTU size:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the

MTU Size

field, enter a value from 64 to 1500.

6.

Click the

button.

Your settings are saved.

If you suspect an MTU problem, a common solution is to change the MTU to 1400. If you are

willing to experiment, you can gradually reduce the MTU from the maximum value of 1500

until the problem goes away. The following table describes common MTU sizes and

applications.

Table 2.

Common MTU sizes

1500

The largest Ethernet packet size. This setting is typical for connections that do not use

PPPoE or VPN and is the default value for NETGEAR routers, adapters, and switches.

1492

Used in PPPoE environments.

1472

Maximum size to use for pinging. (Larger packets are fragmented.)

1468

Used in some DHCP environments.

Optimize Performance

You can set up the router to optimize performance for applications such as Internet gaming, high

definition video streaming, and VoIP communication. By default, the router uses Wi-Fi

Multimedia Quality of Service (WMM QoS).

This chapter contains the following sections:

•

Optimize Internet Streaming with QoS

•

Add QoS Rules by Service

•

Improve Network Connections with Universal Plug and Play

•

Optimize Internet Streaming with QoS

You can use Quality of Service (QoS) to assign high priority to Internet streaming,

applications, and services.

Figure 5. QoS can assign high priority to streaming from the Internet

NETGEAR recommends that you enable this feature only if you use streaming Internet.

When QoS assigns a high priority to streaming video, it also assigns lower priority to the rest

of your Internet traffic. That means other tasks like downloading content from the Internet

take longer.



To turn on Internet access QoS:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the address field of the web browser, enter

http://www.routerlogin.net

or

.

A login screen displays.

3.

Enter the router user name and password.

The user name is

password are case-sensitive.

Add QoS Rules by Service



To add a QoS rule for a service:

1.

Launch a web browser from a computer or wireless device that is connected to the

network.

2.

In the address field of the web browser, enter

http://www.routerlogin.net

or

.

A login screen displays.
