Netgear WNR200v4 사용자 설명서

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. 

1500

The largest Ethernet packet size and the default value. This is the typical setting for 
non-PPPoE, non-VPN connections, 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 have 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.

Select Advanced > Setup > WAN Setup. 

The WAN Setup screen displays.

In the MTU Size field, enter a new size between 64 and 1500.

Click the Apply button.

The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host 
Configuration Protocol (DHCP) and Routing Information Protocol (RIP).

The router is shipped preconfigured to use private IP addresses on the LAN side and to 
function as a DHCP server. The router’s default LAN IP configuration is:

LAN IP address. 192.168.1.1

Subnet mask. 255.255.255.0

These addresses are part of the designated private address range for use in private networks 
and should be suitable for most applications. If your network has a requirement to use a 
different IP addressing scheme, you can make those changes on the LAN Setup screen.
