network.
2.
Type

5.
In the
MTU Size
field, enter a value from 64 to 1500.
6.
Click the
Apply
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.)

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
or
.
A login screen displays.
3.
Enter the router user name and password.
The user name is
admin
. The default password is
password
. The user name and
password are case-sensitive.
