Sure! Sorry I just got a walkthrough from a different site and wanted to try that first so that I wont bother you guys with something I could've found off the net.
Heres the walkthrough I found.
Connecting Two WRT54G Routers Together
Product Class:
WRT54G
Operating System:
N/A
Q U E S T I O N
How do I setup a WRT54G behind another WRT54G?
A N S W E R
WRT54G (first) ----------> WRT54G (second)
During this article, the two routers will be referred to as the “first” router (the main router), and the “second” router (the router that you are connecting to the first). The information assumes that both routers are Linksys WRT54G routers both with default factory settings to start; however, if you are familiar with the steps, they can apply to other routers and other manufacturer routers as well. Please contact the appropriate manufacturer for assistance.
Note: Having a “Dual Router Network” can potentially cause unexpected problems during the troubleshooting process if you were to ever have a problem. Be sure to record and remember any settings that are changed during this setup process. Settings that are changed are summarized at the end of this article.
Configuring the “second” router
1. With the “second” router powered on, and nothing plugged into any of its network ports, hold in the Reset button on the unit for about 30 seconds.
2. Connect one computer (it does not matter which one) into one of the numbered ports on the back of the “second” router, then restart or turn on that computer.
3. Verify that you are getting a Link light that matches the port to which you plugged the computer into. For example, if the computer was plugged into port 2, then the Link light on the front of the router for the number 2 port should be lit.
4. When the computer finishes its start up, open a web browser.
5. In the “Address Bar” type
http://192.168.1.1 and press the [Enter] key on your keyboard
6. A box should appear asking for a “User Name” and “Password”. Leave the “User Name” field empty and type your WRT54G’s password into the “Password” field (The default “Password” is admin) and click the OK button.
7. The router “Setup” page should load.
8. You need to change two options on this page.
Local IP Address: change to 192.168.1.2
DHCP Server: set to Disable
9. Click on the Save Settings button toward the bottom of the page to save changes, and then close your web browser.
Physically connecting the two routers
10. Unplug the power to both “first” and “second” routers.
11. Take a straight-through network Ethernet patch cable and connect it to a free numbered port of the “first” router (1, 2, 3, or 4), and plug the other end of the cable into port 4 of the “second” router.
12. Plug the power cord first the “first” router, and then the “second” router.
13. At this point, the two routers are now connected and on the same network. Ports 1, 2, and 3 on the “second” router along with the remaining open ports on the “first” router are now available for other devices to plug into. You also have another wireless access point on the “second” router. Be sure to change the wireless SSID and channel on the “second” router so that they do not conflict with the “first” router.
To recap the settings of both routers:
“First” router: (default factory settings)
Local IP address: 192.168.1.1
DHCP Server: Enable
“Second” router
Local IP address: 192.168.1.2
DHCP Server: Disable
The “second” router can now be easily referred to as a Wireless 3-port switch.
If any of the steps do not work, or if you are having other difficulties, please contact Linksys Technical Support for further assistance.
