What IP Address Should I Use?


Connecting to the Router

Overview
--------
Settings on the router are controlled through a browser. You
can connect to the router on your local network by opening a
computer browser and typing the router IP address in the
browser address bar.

If your local network IP address range is 192.168.*.*, and
the factory IP (192.168.1.1) is not in use, you can change
the settings on the router just by connecting it to your local
network. Just run an ethernet cable from any switch on your
local network to port 1 of the 4 ports on the router (the
WAN port is not used in this configuration).

If your local network IP address range is 192.168.*.*,
but 192.168.1.1 in use (determine if in use with ping),
you could turn off or unplug the machine using that IP,
change the IP on the router, and then put that machine back
on the network. However, if you are not using 192.168.*.* as
your local address range, or 192.168.1.1 is in use and cannot
be temporarily disabled, do a "Direct Connect to Router".
If 192.168.1.1 will work, connect the router to your local
network and go to "Setup as local WAP".

Direct Connect to Router
------------------------
Plug ethernet cable from a computer into one of the 4 router ports.
(not the WAN port).
Reboot computer, or release and renew IP settings:
ipconfig /release
ipconfig /renew

Factory IP: 192.168.1.1
User: (blank)
Password: admin

You need to change the local IP address of the router if
192.168.1.1 is already in use on your local network, or you
are using the 10.*.*.* address range. If you are using the
192.168.*.* address range, you can test to see if 192.168.1.1
is in use by typing this from a computer that is on the local
network:
ping 192.168.1.1.
Use ping to find an unused IP address on your local network.

Change Router local IP address
------------------------------
Setup > Advanced Routing > Operating Mode: Router
[Save Settings]
Setup > Basic Setup > Router IP > Local IP Address: ?.?.?.?
(replace ?.?.?.? with your local IP address for the router)
DHCP Server: Disable
Timezone: {YourTimeZone}
[Save Settings]

Remove the computer ethernet cable, and return it to the normal port
(internet modem or switch).
Plug ethernet cable from modem or switch to port 1 of the 4 router ports.
(note: the WAN port on the Linksys is not used in this configuration)
Restart the computer.
Power cycle the router (unplug for 30 seconds).

When the computer is restarted, you should be able to access the Linksys at
the new IP address. If not, restart both the computer and power cycle
the router at least twice to be sure. If you cannot connect,
hold the reset button on the back of the router for 30 seconds
and start over.

Setup to use as a Wireless Access Point (WAP)

Setup as local WAP
------------------
Wireless > Basic Wireless Settings > Wireless Network Name (SSID): {YourSSID}
(pick an SSID that is not in use within range of your WAP)
[Save Settings]
Wireless > Wireless Security > Security Mode: WPA2 Personal
WPA Algorithms: AES
WPA Shared Key: {YourPasswordHere}
[Save Settings]
Administration > Management > Password: {ADifferentPasswordHere}
(the user name may be blank or anything when logging into the Linksys)
If you lose the password, use the reset button and then
setup the router all over or restore the backup file.

Administration > Config Management: Backup
Save the backup file. If you need to reset the router in the
future, you can restore this file and not go through the
complete setup.

You can plug other computers or devices into the other 3
free router ports (do not use the WAN port).

Setup to use as a switch only

Do Setup to use as a Wireless Access Point (WAP) and then do:
Wireless > Wireless Security > Wireless Network Mode: Disabled

Setup to use as a Router

A Router is needed if you have more than one internet connected device.
A Router is useful even for a single device to provide security features
that prevent unauthorized access to devices on your network.
