Note: If you change the start or end values, make sure the values are still within the same subnet
as the gateways IP address. In other words, if the gateways IP address is 192.168.1.1 (default)
and you change the DHCP start/end IP addresses to be 192.128.1.2/192.128.1.100, you will not
be able to communicate to the ADSL Router if your PC has DHCP enabled. In addition to the
DHCP server feature, the ADSL Router supports the DHCP relay function. When the ADSL
Router is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the
ADSL Router is configured as DHCP relay, it is responsible for forwarding the requests and
responses negotiating between the DHCP clients and the server.
By turning off the DHCP server and relay the network administrator must carefully configure the
IP address, Subnet Mask and DNS settings of every computer on your network. Do not assign
the same IP address to more than one computer and your ADSL Router must be on the same
subnet as all the other computers.

Diagnostic Test is used for investigating whether the ADSL Router is properly connected to the
WAN Network. See Fig 1-9. This test may take a few seconds to complete. To perform the test,
select your connection from the list and press the Test button. Before running this test, make
sure you have a valid DSL link.
