How to connect a router to another router:
Advantages of connecting a router to another router:
- You may have a very large home and single unit might not be powerful to send the wireless signal all over. In this case you can add second unit to increase the wi-fi signal also increase the number of Ethernet ports to connect the wired devices.
- You may have a wired network and want to add some new wi-fi devices to it. In this case you can add wireless access point to get wi-fi signal.
- To create open wi-fi for guest users and not allowing them to enter into your main network.
Steps to connect 2 routers to each other:
Let’s take an example that you have 2 Linksys routers that you want to connect to each other.
The main Router A (Linksys E3000) will be always connected to the modem and it will be the primary unit for the Internet connection. You don’t need to change any settings on main unit E3000.
Router B (Linksys E1000) will be the additional unit that you want to add in the network.
There are 2 types of connections.
Type 1: LAN to LAN connection: In this type of connection, you are going to attach Ethernet (LAN) port of E3000 to Ethernet port of E1000. In this connection type all the computers connected to both the routers will be in the same IP address range and thus will be able to share the resources within the network. In this connection type E1000 will act as a wi-fi access point and switch. E1000 will not assign IP address.
Let’s consider the IP address of both the routers is same (192.168.1.1).
Connect one computer to E1000 with the Ethernet cable.
Open the setup page and change the IP address of E1000 to 192.168.1.2.
You will also need to DISABLE the DHCP server on E1000.
Now connect Ethernet cable from any available Ethernet port of E3000 to one of the Ethernet port (1, 2, 3 or 4) of E1000. (Do not use Internet port of E1000).
Power cycle both the routers and you are good to go.
You can also connect your wired devices to remaining 3 Ethernet port on E1000.
It is not necessary to use same wireless settings on both the wireless routers A and B. You can create 2 different wi-fi SSIDs and different security keys for both the SSIDs.
If you are using the same wireless network name and password for both the routers then make sure that wireless channel on both the routers will be different.
Type 2: LAN to WAN connection:
Let’s consider the same example of Linksys E3000 and Linksys E1000 where E3000 is the main router. In LAN to WAN connection type you are going to connect Ethernet port of E3000 to the Internet (WAN) port of E1000. In this connection type both the routers will assign IP addresses and will have there own network. Thus computers or devices connected to E3000 will not be able to communicate with E1000 and vice versa.
First connect one computer to E1ooo with the Ethernet cable.
Open the setup page of E1000 using 192.168.1.1.
Change the Local IP address of E1000 to 192.168.2.1. Power cycle E1000.
Now connect Ethernet cable from E3000 to the Internet (WAN) port of E1000.
Power cycle both the router and you are good to go.
I will suggest you to create 2 different wireless networks for both the routers so that you will come to know which network you are connecting your computer.
