Knowledge Center ---------------------------------------------------------------------------------------------- 1. MTU: 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. 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 provides it.
III Features & Configurations 33 3. Server Name: This is the descriptive name of the server. Only enter it if your ISP provides it. Static IP Configuration Procedures: ① Internet Connection Type: Select Static IP. ② IP Address/Subnet Mask/WAN subnet mask/Gateway/Primary DNS Server/Secondary DNS Server: Enter the ISP information you gathered in 1GettingPrepared. ③ Click Save to save your settings.
III Features & Configurations 34 DHCP Configuration Procedures: ① Internet Connection Type: Select DHCP. ② Click Save 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:
III Features & Configurations 35  A secure website that does not open, or displays only part of a web page  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.
III Features & Configurations 36 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. 2.3 WAN Speed Click Basic -> WAN Speed to the configuration interface. Here you can configure the WAN speed and duplex mode. Tip-------------------------------------------------------------------------------------------------------------------------------------------- 1. The router operates in "Auto-negotiation" (or Auto) mode by default. Usually, it works for most cases. In some situations, you might need to change the port mode. For example, if the cable connected to your router's WAN port is longer than 100m, you may need to use 10M full-duplex or 10M half-duplex for better performance. Ensure that your router's WAN port operates with the same speed and duplex mode as the remote link partner. If not, your router's WAN port may not receive and send data.
III Features & Configurations 37 2.4 DNS Settings Click Basic -> DNS Settings to enter the DNS configuration interface. Configuration Procedures: ① DNS Settings: Check to enable the DNS settings. ② Primary DNS Server: Enter the IP address of your ISP’s primary DNS server. ③ Secondary DNS Address: If a secondary DNS server address is available, enter it here. This field is optional. ④ Click Save to save your settings. Note --------------------------------------------------------------------------------------------------------------------- The default DNS settings are recommended. Only change the DNS default settings if you know that your ISP requires specific servers. If incorrect DNS settings are configured, webpages will be unable to open.
III Features & Configurations 38 2.5 MAC Clone Some ISPs (Internet Service Providers) require end-user's MAC address to access their network. This feature copies your current PC's MAC address to the router. Click Basic -> MAC Clone to enter the MAC Clone screen. Knowledge Cente------------------------------------------------------------------------------------------------ 1. Restore Default MAC: Reset the router’s WAN MAC to factory default. 2. Clone MAC: Clicking this button copies the MAC address of the computer that you are now using to the router. Also, you can manually enter the MAC address that you want to use. You have to use the computer whose MAC address is allowed by your ISP. To restore default MAC address: ① Click Restore Default MAC. ② Click Save to save your settings.

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 Basic -> DHCP Server to enter the DHCP Server screen. Here you can change the DHCP IP address pool and lease time. Configuration Procedures: ① DHCP Server: Select whether to enable or disable the DHCP server feature. ② Start IP/End IP: 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.

Tip--------------------------------------------------------------------------------------------------------------------------------------------- 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. 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
