Router IP Address
IP Address This is the IP address of the router and is used
as the base for all of your local network settings .
Subnet Mask This is the subnet mask address for your
router . It offers a selection of addresses from a drop-down
menu . Most users will not need to change this setting .
Device Name The default device name is Ciscoxxxxx .
xxxxx represents the last 5 digits of your serial number .
This can be found on the bottom of the router . (The Device
name is also the Router’s NetBIOS name .)
NOTE:
If you used the setup software
for installation, then the device name is
synchronized with the name of your wireless
network (up to 15 characters) .
DHCP Server Settings
The settings allow you to configure the Router’s 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 or device on your network .
NOTE:
If you choose to enable the DHCP server
option, make sure there is no other DHCP server
on your network .
DHCP Server Setting

by your Router when it functions as a DHCP server . (The
first IP address assigned by the Router will be randomly
