CASCADING A ROUTER (Same subnet)
Have you ever wondered how you could use an old router to extend your networks capablities? Why let such a useful peice of equipment go to waste?
This section will show you how to have a second router connected to your network (LAN to LAN) and utilize the LAN and Wireless functions of the router to extend your networks capabilities.
Second Router (Slave Router)
The process starts on your Second Router first.
Firstly, connect your computers LAN port Directly to any of the LAN ports on your router (2nd Router) via an ethernet cable.
Firstly start by loading up your configuration page of your router.
To do this, look on the bottom of your router, and there should be a default gateway and a Username and Password. Enter the default gateway into your internet browser and use the credentials on the bottom of your router.
------------------------------------------------------------------------------------------
If there is no information on the bottom of your router, do the following:
1 - Press Windows Key + R at the same time
2 - Type "cmd" without the quotes and click Run
3 - Type "ipconfig" once cmd is open
4 - Note down the IP address under Default Gateway
Type the IP address you noted down in your Internet Browser
It may ask you for a Username and Password
For a Netgear:
Username = admin
Password = password
For a Linksys:
Username = admin
Password = admin
To properly find the correct Username and Password for your router, visit

------------------------------------------------------------------------------------------
Once the configuration page is open, the first step is to set the routers DNS server to the IP address of your first router (Master), in this case my first router has an IP address of 192.168.1.1, so set your primary and secondary DNS to 192.168.1.1 (or whatever applies to your setup, may be 192.168.0.1)
The next step is to change the IP address of your Slave router to one increment higher than your first router(Master),
e.g Master Router = 192.168.1.1, so Slave Router = 192.168.1.2
All you really need to do is turn DHCP off, as your master router will assign the IP addresses (hence the "Slave" term)
Once complete, disconnect the Ethernet cable between your Slave router, and connect your PC straight to the Master router (This should be the first time you connected to your master router in this whole process)
First Router (Master) (192.168.1.1)
Access the configuration page, similarly to the way in which done previously.
Change the DHCP range of the router(Master) from 192.168.1.2-254, to 192.169.1.3-254, so the address range is one increment above the Slave routers IP address.
So this means that the Slave router is not in the master routers DHCP address range.
