How to Cascade a Cisco Router’s…!!!!!!

Step 1 : Designate which one of your routers will be the primary router and which will be secondary. Your primary router should already be configured as, or with your modem.

Step 2 : Connect your computer directly to your secondary router using an Ethernet cable by plugging the cable into one of the numbered Ethernet ports on the back of the router and to an Ethernet port on your computer. Make sure it is not plugged into your primary router.

Step 3 : Access your router’s web-based configuration menu. Connect to the router’s IP address with a web browser.

• Depending on the make of your router, you may have to navigate to a specific URL to access your router’s web-based configuration menu. Consult your router’s user manual to find out.

Step 4 : Look for the local IP settings and reset the router’s IP address from its default settings. The key here is to make sure that your secondary router has a different final digit than the IP address of your primary router.

• An example IP for your primary router is 192.168.1.1. So an example of your secondary router’s IP address could be 192.168.1.2.

Step 5 : Locate the router’s DHCP Server settings and turn them off.

Step 6 : Make sure your router is set to router operating mode. This is often located in an advanced settings menu.

Step 7 : Plug another Ethernet cable into one of the numbered Ethernet ports on the back of the primary router. Plug the other end of that cable into a numbered Ethernet port on the back of the secondary router. Your routers are now cascaded.

Method 2 of 2 :
Connect Ethernet to Internet or LAN to WAN 

Step 1 : Connect your computer to your secondary router and access the web-based configuration menu.

Step 2 : Change the local IP address so that the second-to-last digit is different from your primary router.

• If your primary IP address is 192.168.0.1 then your secondary router’s IP address should be something like 192.168.2.1.

Step 3 : Save your IP address changes.

• Disconnect your secondary router from your computer.
  

Step 4: Plug an Ethernet cable into one of the numbered Ethernet ports on the back of your primary router.

Plug the other end of the cable into the Internet port of your secondary router. Your routers are now cascaded.
