default, DHCP is enabled. If the router fails to obtain an IP address over DHCP it will Auto IP
with 169.254.X.Y.
1) Insert the provided CD-ROM into a computer also on the network.
2) Run the IPSetup.exe program from the CD-ROM.
3) Find unit under “Select a Unit”.
a. Change IP address to match that of your PC if DHCP has failed.
i. You will know DHCP has failed if the router’s IP address is AutoIP at
169.254.X.Y.
ii. If successful, it will say DHCP’d at ex: 192.168.0.100 however your DCHP Client
is set up.

Committing Changes to the Settings
♦Changes made to the settings of the router will not take effect until the router is
restarted.
♦Changes will not be stored if the router’s power is removed prior to rebooting.
♦The router detects changes and will prompt you with a red notice box to reboot the
router after change.
♦NOTE: The router does not need to be restarted after every change. Multiple changes
can be made before a restart, but they will not be committed until the router is
rebooted.
♦The webpage will redirect to our rebooting page shown below.
♦After the router has restarted, which can take up to 15 seconds, the router will
automatically redirect to the diagnostics page. You will know the save was successful if
the red box is no longer present.
If you don’t understand the load screen reference you need to add Stanley Kubrick’s
2001: Space Odyssey to your must watch list. We recommend finding a Betamax version.
