Wireless-G Broadband Router
MTU MTU is the Maximum Transmission Unit. It specifies
the largest packet size permitted for Internet transmission.
Select Manual if you want to manually enter the largest
packet size that is transmitted. To have the Router select
the best MTU for your Internet connection, keep the
default, Auto.
Size When Manual is selected in the MTU field, this option
is enabled. Leave this value in the 1200 to 1500 range. The
default size depends on the Internet Connection Type:
DHCP, Static IP, or Telstra: 1500
PPPoE: 1492
PPTP or L2TP: 1460
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.
Router IP Address
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, make sure there is no other
DHCP server on your network.
Network Address Server Settings (DHCP)
DHCP Server DHCP is enabled by factory default. If you
already have a DHCP server on your network, or you do
not want a DHCP server, then select Disable (no other
DHCP features will be available).
Starting IP Address Enter a value for the DHCP server
to start with when is
suing IP addresses. Because the
Router’s default IP address is 192.168.1.1, the Starting IP
Address must be 192.168.1.2 or greater, but smaller than
192.168.1.253. The default is 192.168.1.100
.
Maximum Number of DHCP Users Enter the maximum
number of PCs that you want the DHCP server to assign
IP addresses to. This number cannot be greater than 253.
The default is 50.
Client Lease Time The Client Lease Time is the amount
of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the
amount of time, in minutes, that the user will be “leased”
this dynamic IP address. After the time is up, the user will
be automatically assigned a new dynamic IP address, or
the lease will be renewed. The default is 0 minutes, which
means one day.
Static DNS (1-3)
The Domain Name System (DNS) is how
the Internet translates domain or website names into
Internet addresses or URLs. Your ISP will provide you with at
least one DNS Server IP Address. If you wish to use another,
enter that IP Address in one of these fields. You can enter up
to three DNS Server IP Addresses here. The Router will use
these for quicker access to functioning DNS servers
.
WINS The Windows Internet Naming Service (WINS)
manages each PC’s interaction with the Internet. If you
use a WINS server, enter that server’s IP Address here.
Otherwise, leave this blank.
Time Setting
Select the time zone in which your network functions
from this drop-down menu. (You can even automatically
adjust for daylight saving time.)
Time Setting
Click Save Settings to apply your changes, or click Cancel
Changes to clear your changes.
Setup > DDNS
The Router offers a Dynamic Domain Name System (DDNS)
feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when
you are hosting your own website, FTP server, or other
server behind the Router.
Before you can use this feature, you need to sign
up for DDNS service with a DDNS service provider,
www.dyndns.org or www.TZO.com. If you do not want
to use this feature, keep the default setting, Disable.
