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.

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, 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 and 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.
