User's Manual

Under Router Settings click Wireless. Take note of the Network name (SSID), Password, Security mode, and Channel.
Under Router Settings, click Connectivity, then click the Local Network tab. Take note of the DHCP server’s IP address range (192.168.1.100 to 192.168.1.149 by default).
To use your old router as an access point, do the following:
With your computer connected to your old router, log into its browser-based administration utility.
NOTE
Save your changes by clicking Apply after finishing each step below.
Open the setup page for the local network (LAN).
In the Router IP address field, enter an unused IP address for the LAN network of your new router.
For example, if your new router has an IP address of 192.168.1.1, you should choose an IP address on the 192.168.1.0 network. You can choose any address within the range of
192.168.1.2 to 192.168.1.254. You should exclude addresses in the range that will be used by the DHCP Server of your new router (192.168.1.100 to 192.168.1.149). A safe
choice might be 192.168.1.250. Take note of this address, because this will be the address that you will use to manage your old router in the future.
In the Subnet Mask field, enter "255.255.255.0" or, if available, select that subnet mask from a drop-down list.
Disable the DHCP server on your old router. (Because your old router will be operating as an access point instead of a router, you don’t want it to distribute IP addresses. There
should be only one active DHCP server on your network, and that should be your new router.)
To reconfigure the wireless network on your old router, do the following:
Open the wireless network setup page.
Change the network name (SSID) to match the name of your new network. Having the same network name and security settings enables you to seamlessly roam between your
new router and your old router.
Change the security mode to match the security mode on your new router.
Change the password (sometimes called the pre-shared key) on your old router to match the password on your new router.
Change the wireless channel to a non-conflicting channel. Some manufacturers have an Auto function for channel selection that automatically selects a wireless channel that
does not interfere with other nearby wireless networks. If your old router supports an Auto function, select that. Otherwise, you may need to manually select the wireless
operating channel on your old router. In the 2.4 GHz wireless spectrum, there are only three non-overlapping channels: 1, 6, and 11. Pick a channel that does not overlap the
operating channel of your new router. For example, if your new router is operating on channel 11, configure your old router for either channel 1 or channel 6.
Connect an Ethernet network cable to one of the LAN/Ethernet ports on your old router and an Ethernet port on your new router.
CAUTION
Do
not
connect the cable to the Internet port on your old router. If you
do, you may not be able to set up the router as an access point on the
current network.
