•You experience problems connecting to your ISP or other Internet service,\
 and the 
technical support of either the ISP or NETGEAR recommends changing the M\
TU setting. 
These web-based applications might require an MTU change:
- A secure website that does not open, or displays only part of a web page\
- Y
ahoo email
- MSN portal
- America Online’
 s DSL service
• Y
ou use VPN and have severe performance problems.
•Y
ou used a program to optimize MTU for performance reasons, and now you h\
ave 
connectivity or performance problems.
Note: An incorrect MTU setting can cause Internet communication 
problems. For example, you might not be able to access certain 
websites, frames within websites, secure login pages, or FTP or POP 
servers.
To change the MTU size:
1.  Launch a web browser from a computer or WiFi device that is connected to\
 the network.
2.  Enter  http://www
 .routerlogin.net.
A login window 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.
The BASIC Home page displays.
4.  Select  ADV
 ANCED > Setup > WAN Setup . 
5. In the MTU Size field, enter a value from 64 to 1500.
6.  Click the  Apply button.
Your change is 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  
MTUApplication
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, an\
d switches.
1492 Used in PPPoE environments.
1472 Maximum size to use for pinging. (Larger packets are fragmented.)
1468 Used in some DHCP environments.
1460 Usable by AOL if you do not send or receive large email attachments, for example.
1436 Used in PPTP environments or with VPN.
1400 Maximum size for AOL DSL.
576 Typical value to connect to dial-up ISPs.
 
Enable the Bridge or Add a VLAN Tag Group
Some devices, such as an IPTV, cannot work behind a router’s network address translation 
(NAT) or firewall. Based on what your Internet service provider (ISP) re\
quires, for the device to 
connect to the ISP’s network directly, you must enable the bridge between the device and the 
router’s Internet port or add new VLAN tag groups to the bridge. 
Enable the Bridge 
If your device, such as an IPTV, is connected to the router’s Ethernet port or WiFi network, 
you can enable the bridge so that the packets sent between the device an\
d the router’s 
Internet port are not processed through the router’s network address translation (NAT).
To enable the bridge:
1. Launch a web browser from a computer or WiFi device that is connected to\
 the network.
2.  Enter  http://www
 .routerlogin.net.
A login window 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.

Add VLAN Tag Groups
You can add VLAN tag groups to the bridge and assign VLAN IDs and priority values to each 
VLAN tag group.
If you add a VLAN tag group to the bridge, packets sent between the device and the router’s 
Internet port are not processed through the router’s network address translation (NAT) or 
firewall.
To add a VLAN tag group:
1. Launch a web browser from a computer or WiFi device that is connected to the network.
2. Enter http://www.routerlogin.net.

field.
•If you are not sure, click the Speedtest button.
Speedtest verifies the upstream speed of your Internet connection. The Uplink 
bandwidth Maximum field displays the result of the test.
8. Click the Apply button.
The router assigns a high priority to Internet traffic from your gaming devices to the 
Internet.
Add Upstream QoS Rules
You can give prioritized Internet access to the following types of traffic:
•Specific applications
•Specific online games
•A specific device by MAC address
To specify prioritization of traffic, create a policy for the type of traffic and add the policy to the 
QoS Policy table in the QoS Setup page. For convenience, the QoS Policy table lists many 
common applications and online games that can benefit from QoS handling.

Optimize Video Streaming with Downstream QoS
Downstream QoS prioritizes Internet traffic from the Internet to your network. This delivers 
better performance when you stream Internet video, such as when you watc\
h YouTube 
videos.
Best effort traffic
Internet
High priority traffic
 
Figure 8. Downstream QoS assigns high priority to video streaming from t\
he Internet
NETGEAR recommends that you enable downstream QoS only if you watch stre\
aming 
Internet video. When downstream 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 enable downstream QoS:
1.  Launch a web browser from a computer or WiFi device that is connected to\
 the network.
