The best MTU setting for NETGEAR equipment is often the default value. In some situations,
changing the value fixes one problem but causes another. Leave the MTU unchanged unless
one of these situations occurs:
•
You experience problems connecting to your ISP or other Internet service, and the
technical support of either the ISP or NETGEAR recommends changing the MTU 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
-
Yahoo email
-
MSN portal
-
America Online’s DSL service
•
You use VPN and experience severe performance problems.
•
You used a program to optimize MTU for performance reasons, and now you are
experiencing 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 an Internet browser from a computer or wireless device that is connected to the
network.
2.
Type
or
.
A login window opens.
3.
Enter the router user name and password.
The user name is

. The default password is

. The user name and
password are case-sensitive.

In the
MTU Size
field, enter a value from 64 to 1500.

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
MTU
Application
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.
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) requires, to allow 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 and the router’s
Internet port are not processed through the router’s Network Address Translation (NAT).
To enable the bridge:
1.
Launch an Internet browser from a computer or wireless device that is connected to the
network.
2.
Type
or
.
A login window opens.
3.
Enter the router user name and password.

•
If your device is connected to your router’s WiFi network, select a
Wireless

Note:
You must select at least one
Wired Ports

Click the
Apply
button.
Your settings are saved.
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 an Internet browser from a computer or wireless device that is connected to the
network.
