How to Connect a Linksys Wireless Router to a Wired Router for Internetby Andrew Mikael
If you have a Linksys wireless router in addition to a wired router for connection to the Internet via Ethernet cable, you can simply add the second wireless device to the setup and allow wireless computers, printers and other devices to connect over the air. This adds wireless connectivity to your network without the need to disconnect and reconfigure the original router.
Connect one end of an Ethernet cable to a numbered output port on the wired router, and connect the other end to the uplink port on the wireless Linksys router. The port is labeled "Uplink" on most Linksys routers, and can be found to the right of the other Ethernet ports. Turn both routers on.
Turn on a computer with wireless capability and connect to the new wireless network. By default, Linksys routers use "Linksys" as the network name.
Open a web browser and type "192.168.0.1" into the address bar (without the quotes), then press "Enter." This will open the wireless router's settings page. Enter your user name and password to continue. If you have not set up the router with a user account, leave the user name field blank and enter "admin" as the password.
Click the DHCP tab and disable the DHCP service. Keeping DHCP enabled will cause network conflicts between the two routers.
Turn on any computers connected to the wired router and note their IP addresses. (You can find the IP address by running the ipconfig command in a command prompt in Windows, or by opening the Network section of the System Preferences in OS X.) You need these numbers in order to set an accurate IP address for the wireless router.
Click to open the LAN IP Address options in the wireless router's settings and change the IP to match the IP address of the wired router, changing the last digits to a unique number. For example, if the wired router has computers using XXX.XXX.X.1 and XXX.XXX.X.2, change the wireless router's LAN IP to XXX.XXX.X.3 to keep the address unique. This prevents address conflicts between the devices.
