Today I bought My Linksys WRT54G2 ( Wireless G broadband) Router. In this post I will talk on how you can configure , With Lan Wire and Wireless , the router with ADSL broadband Modem. This can be similar to other modems also. Configuring the router was little tricky for me. I say tricky because its not hard its just we need to know how to do the right way. So lets get to the topic.
What I had ?
ISP : BSNL borad band
ADSL Modem SMART AX MT882 ( provided by broad band )
My ISP had give me a Static IP and Some IP for default gateway.
New : Linksys WRT54G2 Router
My Goal :
Configure my Linksys WRT54G2 Router to talk to Modem and My computer to Router
Configure for both Wired and Wireless connection
Though Linksys router / modem comes with a CD which has setup for making this work but it did not work for me. I had to do the manual way. In case you have any previous settings, please reset to factory settings.
Update : This should also work with
Linksys WRT54G Router with huawei MT 880 or 882 BSNL modem. Thye have similar settings
ADSL Modem/Router UT-300R2U with Linksys Wireless Router WRT54G
BSNL smartAX MT882 modem and linksys WRT54G router
So finally It Should look like this :
My Home Wifi network
Configuring for Wired Connection :
Saving Previous Settings :
Make a note of all your IP, DNS IP address and Default Gateway which you can find in your current Ethernet /LAN connection. I had a static IP. The below step tells you how to do it.
My Network Place > View Network
Connection. Select the network
which is for your Ethernet.
Right Click the network
connection. Then go to properties You will see lot of things listed there. Look for Internet protocol ( TCP / IP ). It could also be IPv4
Now Click on properties button. It will open another window . Under general tab of the windows. You can see if the IP is set to manual or Dynamic.
If manual You will have all the IP, DNS, gateway listed right there. Save the ip address on notepad .Also if you have any DNS IP save it too.
Now change your LAN settings to Dynamic IP and Remove option for DNS. So its all Dynamic no manual configuration.
Do not change any configuration of your modem. Let it be the same and keep it on.
We will need them when we actually make the modem and router talk.
Detecting Router and Changing Router IP Address
Unplug the network cable connected to your current Modem.
Plug the network cable ( Mine was Blue ) which comes with the Router Box pack to your computer. The other end goes into any of the Router Ethernet Port ( 1 or 2 or 3 or 4 )
Now type in 192.168.1.1 in IE or Firefox or any browser. You will prompted for password which is admin. You must be logged into Linksys Router.
Now since your ADSL modem is also having the same IP , we will change the IP address for WRT54G2 Router to 192.168.5.1
Under Setup >Basic Setup look for Network Setup and Change Router IP. Change to 192.168.5.1 and Save changes.
Since the IP has changed you will need to close the Browser.
Sometimes the IP doesnt change automatically. Do a IPCONFIG / RELEASE and then IPCONFIG / Renew

You will need to configure here Security Mode : WPA Personal, WPA Algorithms: TKIP
WPA Shared Key is what you will need when you connect to your router without wire. This key does the authentication and keep unwanted people away. Add 8 digit alphanumeric key.
