1. MTU: The MTU (maximum transmission unit) is the largest data packet a network device

III Features &Connectivity

transmits. The normal MTU value for most Ethernet networks is 1500 bytes, or 1492 bytes for

PPPoE connections. The best MTU value is often just the factory default value. For some ISPs,

you might need to change the MTU. This is rarely required, and should not be done unless you are

sure it is necessary for your ISP connection. For more information, see WAN MTU Setup.

2. Service Name: This is the descriptive name of the current connection. Only enter it if your ISP

③ Click OK to save your settings.

III Features &Connectivity

DHCP

Configuration Procedures:

① Internet connection Type: Select DHCP.

② Click OK to save your settings.

WAN MTU Setup

The MTU (maximum transmission unit) is the largest data packet a network device transmits.

The normal MTU value for most Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE

connections. For some ISPs, you might need to change the MTU. This is rarely required, and

should not be done unless you are sure it is necessary for your ISP connection. When one

network device communicates across the Internet with another, the data packets travel through

many devices along the way. If a device in the data path has a smaller MTU value than the other

devices, the data packets have to be "fragmented" to accommodate the device with the smallest

MTU value.

The best MTU value is often just the factory default value. In some situations, changing the MTU

value fixes one problem but causes another. Leave the MTU unchanged unless one of these

situations occurs:

A. You have problems connecting to your ISP or other Internet service, and either your ISP or our

technical support suggests changing the MTU value. Below web-based applications might require

an MTU change:

 A secure website that does not open, or displays only part of a web page

III Features &Connectivity

 Yahoo email

 MSN portal

B. You use VPN and encounter serious performance problems.

C. You used a program to optimize MTU for performance reasons, and now you have connectivity

or performance problems.

If you suspect an MTU problem, try changing the MTU to 1400. If this does not help, gradually

reduce the MTU from the maximum value of 1500 until the problem disappears.

The common MTU sizes and applications are listed in the table below.

MTU Application

1500 Typical for connections that do not use PPPoE or VPN.

1492 Used in PPPoE environments.

1472 Maximum size to use for pinging. (Larger packets are

fragmented.)

1468 Used in some DHCP environments.

1436 Used in PPTP environments or with VPN.

Note ---------------------------------------------------------------------------------------------------------------------

A wrong/improper MTU value may cause Internet communication problems. For example, you

may be unable to access certain websites, frames within websites, secure login pages, or FTP or

POP servers.

---------------------------------------------------------------------------------------------------------------------------------

III Features &Connectivity

router's WAN speed and duplex mode.

Tip-------------------------------------------------------------------------------------------------------------------------

1. The best port mode is often just the factory default of "Auto".

2. In some situations, you might need to change the port mode. For example, if the cable

connected to your router's WAN port is too long, you may need to use 10M full-duplex or 10M

half-duplex for better performance.

---------------------------------------------------------------------------------------------------------------------------------

1.5 LAN Settings

Click Advanced -> LAN Settings to enter the configuration screen. Here you can configure the

LAN IP address. This IP address is to be used to access the router’s settings through a web

browser. Be sure to make a note of any changes you apply to this page.

1.7 DHCP Server

DHCP (Dynamic Host Configuration Protocol) assigns an IP address to each device on the

LAN/private network. When you enable the DHCP Server, the DHCP Server will automatically

allocate an unused IP address from the IP address pool specified in this screen to the requesting

device as long as the device is set to "Obtain an IP Address Automatically". If you disable this

feature, you have to manually configure the TCP/IP settings for all PCs on your LAN to access

Internet.

Click Advanced -> DHCP Server to enter the DHCP Server screen. Here you can change the

DHCP IP address pool and lease time.

III Features &Connectivity

Configuration Procedures:

① DHCP Server: Select whether to enable or disable the DHCP server feature.

② IP Pool Start IP Address / IP Pool End IP Address: You can specify the starting and ending

address of the IP address pool here. These addresses should be part of the same IP address

subnet as the router’s LAN IP address.

③ Lease Time: The lease time is a time length that the IP address is assigned to each device

before it is refreshed.

④ Click OK to save your settings.

Tip-----------------------------------------------------------------------------------------------------------------------

1. By default, the router functions as a DHCP server. Do not disable the DHCP server feature

unless you want to manually configure the TCP/IP settings for all PCs on your LAN.

2. Lease time will be renewed automatically upon expiry. No additional configurations are

needed.

3. If you are not an advanced user, the default DHCP server settings are recommended.

---------------------------------------------------------------------------------------------------------------------------------

1.8 DHCP Client List

Click Advanced -> DHCP Client List. You can know whether there are unauthorized accesses by

viewing the client list.

Also, you can specify a reserved IP address for a PC in the LAN. That PC will always receive the

same IP address each time when it accesses the DHCP server. Reserved IP addresses could be

assigned to servers that require permanent IP settings.

III Features &Connectivity

Static Assignment Application Example:

To have a PC at the MAC address of 44:37:E6:4F:37:3B always receive the same IP address of

192.168.0.123.

Configuration Procedures:

① Enter the last number of the IP address you want to reserve, for example, 123.

② Enter the MAC address of 44:37:E6:4F:37:3B.

③ Click Add.

III Features &Connectivity

④ Click OK to save your settings.

Tip-------------------------------------------------------------------------------------------------------------------------

1. If the IP address you have reserved for your PC is currently used by another client, then you

will not be able to obtain a new IP address from the device's DHCP server, instead, you must

manually specify a different IP address for your PC to access Internet.

2. For PCs that has already obtained IP addresses, you may need to perform the Repair action

to activate the configured static IP addresses.
