Thank you for choosing the Linksys E1200/E1500
Wireless-N Router. The Router lets you access the Internet
via a wireless connection or through one of its four
switched ports. You can also use the Router to share
resources such as computers, printers and files.
A variety of security features help to protect your data
and your privacy while you are online. Security features
include Wi-Fi Protected Access 2 (WPA2) security, which
encrypts data on your wireless network; a Stateful Packet
Inspection (SPI) firewall to help block unauthorized access
to your Router; and Network Address Translation (NAT)
technology, which enhances network protection by
allowing your computers to share Internet access through
a single, public Internet IP address. (IP stands for Internet
Protocol.)
Setup and use of the Router is easy using Cisco Connect,
the software that is installed when you run the included
CD. Advanced configuration of the Router is available
through the provided browser-based utility.

by your Router when it functions as a DHCP server. (The
first IP address assigned by the Router will be randomly
selected within the range you specify.)
Because the Router’s default IP address is 192.168.1.1,
the Start IP Address must be 192.168.1.2 or greater, but
smaller than 192.168.1.254. The default Start IP Address is
192.168.1.100.
Maximum Number of Users Enter the maximum
number of computers that you want the DHCP server to
assign IP addresses to. This number cannot be greater
than 253. The default is 50.
IP Address Range The range of available IP addresses is
displayed.
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 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, however, you wish to use
a different DNS server, enter its IP address (you can enter up
to three DNS server IP addresses). These static DNS server(s)
will have higher priority than the ISP’s DNS servers. The
Router will assign these DNS servers to the computers and
other devices in your local network.
