Wireless-G Router for Mobile Broadband

MTU. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. The default setting, Manual, allows you to enter the largest packet size that will be transmitted. The recommended size, entered in the Size field, is 1492. You should leave this value in the 1200 to 1500 range. To have the Router select the best MTU for your Internet connection, select Auto.

Network Setup

The Network Setup section changes the settings on the network connected to the Router’s Ethernet ports. Wireless setup is performed through the Wireless tab.

Router IP

This presents both the Router’s IP Address and Subnet Mask as seen by your network.

DHCP Server Settings

The Router can be used as a Dynamic Host Configuration Protocol (DHCP) server for your network. A DHCP server automatically assigns an IP address to each computer on your network. Select the mode you want the Router to use for its DHCP server function. If you are not sure which mode to select, keep the default, Mode 1 - Fixed configuration (Default).

Mode 1 - Fixed configuration (Default). In this mode, the Router will advertise itself as the DNS server for the clients (computers) to use. The clients will contact the Router for DNS, and its DNS caching server will resolve the addresses for them. This mode is recommended for networks whose UMTS upstream DNS servers change on a connection-by-connection basis, such as networks in the UK.

Mode 2- Network Supplied. Via DHCP, the Router will advertise the DNS and WINS servers it is using. This mode may be suitable for networks whose DNS servers have static addresses.

Mode 3- Manual configuration. You can designate the settings advertised to the clients via DHCP. Complete the Static DNS and WINS fields that will appear. You can specify up to three DNS servers and up to two WINS servers. Make sure these values do not depend on the Router’s static settings.

Network Address Server Settings (DHCP)

The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to each computer on your network. If you choose to enable the Router’s DHCP server option, you must configure all of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on your network.
