ROUTER-CASCADING

Router to router cascading a simple guide NOTE: Before you connect a router to another router, make sure that both have different IP addresses. This is mandatory because both routers may be set to the same IP address by default. If both routers have the same IP address, you need to change the IP address of the second router to prevent any conflict. There are two ways to cascade a router to another router: 1. Connecting one of the Ethernet ports (LAN ports) of the second Router to one of the Ethernet ports (LAN ports) of the main router. 2. Connecting the Internet port (WAN port) of the second Router to one of the Ethernet ports (LAN ports) of the main router. By connecting the second routers Ethernet port to the main routers Ethernet port, the computers connected to both routers will be on the same LAN IP segment. This will allow sharing of network resources within the network. By connecting the second routers Internet port to the main routers Ethernet port, it will be easier to identify which router the computers are connected to since they will have different LAN IP segments. NOTE: Before configuring the second router, make sure that it is not connected to the main router, where the broadband modem is connected. Then follow these instructions:

1. Cascading the Router to Another Router (LAN-LAN) __________________________________________ To cascade your router to another router, you need to perform two steps: 1. Connecting a Computer to the Router 2. Configuring the Router with LAN-to-LAN Connection NOTE: The steps mentioned should be performed on the second router.

Connecting a Computer to the Router 1.Shutdown the computer and plug it to any of the numbered ports at the back of the router. 2. Plug the supplied power adapter in the router.

Configuring the Router with LAN-to-LAN Connection 1.Access the routers web-based setup page {Second Router} To know better how to login to any router click on the link below. How to find Login IP of my router 2.When the routers web-based setup page appears, look for Local IP Address and change it to 192.168.X.2 { Most of the times router IP address is 192.168.X.1 where X starts from 0 to 255 } 3.When the web-based setup page opens, look for DHCP Server and click Disable 4.Click save settings 5.Click Advanced Routing and change Operating Mode to Router.(Depends on the router models and vendors this may

change} 6.Click save settings 7.Connect a standard Ethernet network cable to one of the numbered Ethernet ports on the main router, where the broadband modem is connected. Then, connect the other end of the Ethernet cable to the Ethernet port of the router that you have just configured. PS : If main router has IP address of 192.168.0.1 then the second router should have an IP address of 192.168.0.2 . Then only this kind of router cascade works.

Configuring the Router with Internet-to-LAN Connection NOTE: The steps mentioned should be performed on the second router. 1.Shutdown the computer and plug it to any of the numbered ports at the back of the router. 2.Plug the supplied power adapter in the router. Configuring the Router with Internet-to-LAN Connection 1.Access the routers web-based setup page 2.When the routers web-based setup page appears, look for Local IP Address and change it to 192.168.X.1 Where X is any number between 0 to 255 except the number in first router. [ie: If the IP address of the first router is 192.168.5.1 the X of second router is any number between 0 to 255 other than 5. ] 3.Click save settings. 4. Connect a standard Ethernet network cable to one of the numbered Ethernet ports on the main router, where the broadband modem is connected. Then connect the other end of the Ethernet cable to the Internet port of the router that you have just configured.

How to connect three routers in your network - Three Router cascading In this article we can check how to connect three routers in a network. For beginners connecting three routers may look like a little difficult but actually it is very simple as changing the third octet of the Router's IP address. For example consider the IP address 192.168.1.5, here the 3rd octet is 1. So let us start how to connect three routers in a network.

CONFIGURING ROUTER 1 FOR THREE ROUTER CASCADING

1. Connect your computer to router 1 using an Ethernet cable Note: LAN Port of the Router-1 should be connected to the LAN Port of computer using an Ethernet cable.

Ethernet Port is marked on the above image. 2. Power on router (Computer too !!!) and wait for 30 seconds. 3. On computer , go to command prompt and type ipconfig and press enter

The default gateway address is the IP address of the Router 1. 4. Type the default gateway address on the address bar of your web browser and press enter. 5. Now an Authentication window will appear:

Enter the default user name and password provided by router vendor. Normally it should be admin and admin. To know more about this follow the link below. How to Login a Router or Modem 6. Change the Router 1 IP address to 192.168.1.1 The DHCP server should be enabled. After Changing the router-1 IP address we need to save the settings.

7. Disconnect the router 1 from your computer.

CONFIGURING ROUTER 2 FOR THREE ROUTER CASCADING

The steps 1 to 5 are same for router 2 and router 3. So follow the steps 1 to 5 and then come to the next steps. We need to change the class C IP address of the router 2 to a different number. Here we assign 192.168.2.1 for Router-2. DHCP server of Router-2 should be enabled.

CONFIGURING ROUTER 3 FOR THREE ROUTER CASCADING

The IP address of the router 3 is : 192.168.3.1

DHCP server should be enabled.

CONNECTING THREE COMPUTERS IN THE NETWORK

The points in connecting three routers are: 1. Connect the WAN Port of router 2 to one of the LAN port of the router 1 using an Ethernet cable. 2. Connect the WAN Port of router 3 to one of the LAN port of the router 2 using an Ethernet cable. The Connection Diagram is : Router 1(LAN port)----(WAN Port)Router 2(LAN Port)-------(WAN Port)Router 3 Suggested Topics in Small Office Networking 1. Add a Wireless Router to a Cable modem

Increase the Speed of your Internet connection- Broadband Hack Previously I was thinking like we cannot increase the broadband speed. The reason is we are getting a fixed bandwidth from ISP so there is no way to improve the speed due to this fixed bandwidth. Later I found one tweaking program while searching in forums called TCP/IP optimizer. After using TCP/IP optimizer I feel a noticeable increase in download and upload speed so I would like to share the same idea with my readers. I would like to let you know at the beginning itself that I am not a part of this program development but I just used this program and experienced improvement in my Internet speed. I know it would be better if I show some results from my PC itself. So I provide screen shots of my Internet connection speed before and after using this program for your reference.

MANUAL STEPS TO IMPROVE INTERNET SPEED

If you are not impressed with the idea of installing a third party software and run on your computer, you can follow the manual steps provided below to improve your Internet Speed. 1. Remove Reservable Bandwidth limit in your computer Many are not aware of a Windows feature to keep 20% of Internet connection bandwidth as reserve for applications running on the computer. If you remove this bandwidth reservation, you can add the not using 20% Internet speed to the current Internet speed you are enjoying. In order to do this you have to edit group policy edit and change the bandwidth reserve from default 20% to 0%. Follow the steps below to perform this and increase your Internet speed up to 20%. 1. Type gpedit.msc on Run and click OK 2. Select Computer Configuration and go to Administrative Templates 3. Click on Network 4. Double Click on QOS Packet Scheduler

Now the "Limit Reservable Bandwidth" Window opens and you can see it as not configured. If you read the note there you can see "If you disable this setting or do not configure it, the system uses the default value of 20 percent of the connection." We have to enable this and change the default 20% to 0%. This will increase your Internet speed up to 20%.

Reboot your computer after closing the window. 2. Perform a Power Cycle Most cases a proper power cycle on your network can improve the Internet connection speed currently you are getting. To know more about this follow the link below. How to Perform Power Cycle 3. Remove Temp files and cache It is advised to delete temp files and browser cache in your computer occasionally to speed up your Internet connection. How to Delete Temp files 4.Make sure no one else is Sharing your Internet Connection If you are using Wireless Internet connection, it is better make sure there is no Internet sharing with unauthorised users. To ensure this you have to use best wireless key encryption to protect your wireless network from hackers and intruders. 5. Make sure no unwanted Programs consuming Internet Bandwidth Many users complained about getting slower Internet connection than the ISP offered. After checking their computer, we found many back ground programs consuming considerable protion of their Internet bandwidth. One example is torrent (peer to peer software). After denying the Internet access to those applications, users feel considerable improvement in Internet speed. 6. Make sure Network components are working fine Faulty network swith, Ethernet cable, modem etc can slow down your Internet connection. So you should check your network devices thoroughly and make sure they are working fine. 7. Make sure no Network worms and malicious programs running Malicious programs like network worm etc can consume the Internet bandwidth. So you have to run periodic scan to avoid the presence of these type malicious infections.

The pictures I provide below show the Internet speed I was getting (throughput) before installing TCP/IP optimizer and the current Internet speed I am getting. The Speed I was getting before installing the TCP/IP optimizer This picture shows my old broadband speed before installing the optimizer.

The two things we need to notice are download speed and upload speed. Download speed: 0.46 Upload speed : 0.24 Improved Broadband speed after installing TCP/IP optimizer This is the screen shot of the Internet speed test after installing optimizer in my PC. I found a huge improvement in my broadband connection speed.

You can understand the improved broadband speed from the details below. Download speed: 1.00 Upload speed : 0.44 The result shows now my computer has almost double the speed compared to the previous broadband speed. How it is possible? Anyway I am getting the same connection from the ISP with same bandwidth. So the change is not from the ISP side but from my computer side. So what would be the possible reasons for the improved broadband speed ? The possible reasons for the better broadband speed: 1. It changes the Windows registry value for the optimum performance. 2. TCP Optimizer works by tuning up all the important TCP/IP parameters (MTU, RWIN,QoS,ToS/Diffserv prioritization). It optimizes the TCP/IP suit for better MTU and so the stateful connections(eg:video streaming, downloads) will be faster.
