How to Connect Multiple Routers in Your Wireless Network

What happens if you're routers don't have the RJ45 WAN port, but only the Twisted pair ADSL WAN port? how do i connect them?

Most of the routers have Ethernet port as the WAN port. Please make sure that you are using a Router or gateway.

this technique has helped me to connect to 2 more router can we connect any other router to cascaded 2 more router

We can cascade more than two routers. The limit of the cascade is (theoretically ) the limit of IP ranges.

Eg:


192.168.X.1 if you are using class C IP address. Here the maximum number of router cascade possible is X and it is 255-1 = 254

Thank you for making something so complicated so simple.

could,'t connect the third router in this router configuration. Could you tell me the UP addresses for all routers and the DHCP status ?

I can connect second router to the primary router and now waiting for the third router.

i want to show a wan in a demo...
for that i have 4 routers only...suggest me how can i make my wan...

Hi Prince, You can follow the diagram below to cascade 4 routers.


Router 1(LAN port)----(WAN Port)Router 2(LAN Port)-------(WAN Port)Router 3 (LAN Port) ---(WAN Port) Router 4

I have already wired CAT5 cables the other 3 computers originating from ADSL router 1. Without Wireless formerly all the 3 computer are connected to ADSL router (Router 1). Now to make the other 2 rooms wireless (due to ipad, ipod, etc), how do I do configure the IP and the DHCP so as not to conflict? So now the CAT5cable 1 from ADSL (router 1) go to computer port. Cable 2 will go to LAN of Router 2 (and computer 2 will be conencted to LAN port of router 2) and cable 3 from ADSL will go to LAN of router 3 (computer 3 will be connected to LAN of router 3). Can this be done?

Your network diagram should be:

Router 1: (LAN Port)---> PC1 + (WAN Port) Router 2


Router 2: (LAN Port)-----> PC + (WAN Port) Router 3

Always connect the LAN Port of first Router to the WAN port(some times called Internet Port) of second router.

You can configure the IP address and DHCP according to the blog post.

Can users of 192.168.1.1, 192.168.2.1, 192.168.3.1 all see each other?

@Jimp

May I know what did you mean by seeing each other ?

Your direction to

"1. Connect your computer to router 1 using an Ethernet cable.
Note: The Ethernet cable from the computer should connect to the WAN Port of the Router."

has never worked for me. My Ethernet cable is ALWAYS connected to the LAN port in order to access the router.

great tutorial. i have 2 routers cascaded like this tutorial suggests; both connect to the internet without issue and get their ip addresses according to the router on their respective networks. Is there a way to share files between the two networks? When I am on network 192.168.2 i can connect to both the routers but is there a way that a computer on 192.168.2.x view shared files from a computer on 192.168.1.x? What i would like to get at is 192.168.2.x can see shared files from 192.168.1.x but not the other way around.

The easiest way to share files between computers connected to both routers is to disable the DHCP of Router 2 and give IP address in 192.168.1.X range. Click on the link below and check LAN-LAN cascading for more information.

@Bill

Thanks for your correction. It was my mistake and I corrected it.

Wonderful Guide, thank you

Thanks ! I'll try it. But how can I configure the wifi for each router ?

You can enable Wi-Fi on any of the routers depends on your network needs. If you want to connect all devices to same wireless network, you may enable Wi-Fi on first router and disable wireless on other routers.

Thanks for adding to my knowledge

Hi, Siju,
I have 3 cascading routers connected previously as you described, with appropriate ip addresses.
However, a 4th router was added later with addresses in the 10.0.0.1 and net mask 255.0.0.0. which is different from the earlier 3 (which have 192.168.x.1 and net mask 255.255.255.0).
Everything works. But I notice the gateway for each of the earlier routers is that of the preceding router in the cascade for the 3 with similar (only different 3rd octec) addresses.
Only the 4th router does not follow this 'rule' and has a completely different gateway.

I have no complaints but wonder if it is advisable or advantageous to configure the 4th router in this different fashion.

Thank you in advance for your comments.

Using this method, can I configure each individual router to use a VPN?

What I would like is to have a single internet connection but a number of routers, each configured to VPN through a different country. If I want to change which country a particular device is routed through, I would connect (via Wi-Fi) to the appropriate router.

Furthermore, I would like to connect multiple different devices to multiple different countries simultaneously.

Thanks!
Marc

Having different subnet mask may cause some issues in this network structure.

You can use as long as your ISP doesn't feel any issues with it.

Hi Alex, I have just found and read your article. Actually this is similar with my network environment at home but unfortunately every machines which have connected to different router cannot communicated to each other but every machines able to connect to internet (etc. browsing, download/upload).
Example :
(WAN : Internet) Router 0 (LAN : 192.168.0.254) --> DHCP On
(WAN : 192.168.0.1) Router 1 (LAN : 192.168.1.1) --> DHCP On
(WAN : 192.168.0.2) Router 2 (LAN : 192.168.2.1) --> DHCP On
(WAN : 192.168.0.3) Router 3 (LAN : 192.168.3.1) --> DHCP On

How can I communicate every machines on each different router?
I hope you can help me to solve this issue on my network environment.
Thank you.
