WRT54G - Gives off signal, but cant connect

Question

I have a wireless router that worked perfectly with a cabel modem, but I now have dsl and it will not work. I have tried everything I know how. Reset everything, downloaded firmware, looked at all the other boards, but nothing works. I have tried automatic configuration and PPPoE and neither have worked. My status on the 192.168.1.1 website has my ip and all the fields as 0.0.0.0 and I cant get it to work. I have tried releasing and renewing. 
My ISP is sbcglobal and i have a speedstream modem, if that helps.
Thanks 

Answer 1

A)  In your computer, please make sure that your ethernet adapter, and your wireless adapter, are both set to "Obtain an IP address automatically" and "Obtain DNS server address automatically".  To check these setting do B and C below:
B)  Go to Start > Control Panel > Network and Internet Connections > Network Connections > then right click on "Local Area Connection" and select "Properties".  Then, go to the "General" tab.  Then in the box that says "this connection uses the following items", scroll down to "Internet Protocol TCP/IP" and highlight it.  Next click on the "Properties" button.   On the "General" tab, verify the settings that I mentioned above in A.  If your computer is not set as mentioned above in A, then select the settings in A, then if an "Apply" button appears, click on it, otherwise click on "OK" until all windows are closed.  NOTE:  If you changed any settings, DO NOT exit the windows by clicking on the "X" in the right corner, you must click on "OK". 
C)  Next, repeat the entire step B above, except, this time, in Network Connections, right click on your wireless adapter and select "Properties"
D)  If you changed any settings in B or C, reboot computer, then try again to connect, by ethernet cable, through your WRT54G.  If you have trouble, temporarily turn off your computer software firewall, and try again to connect.
If you still have trouble, try the following:
You need to try again to reset the router to factory defaults.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
11)  If you get this far without problems, then power down your entire network.  Then, using an ethernet cable, connect your speedstream modem to the Internet port of your WRT54G.  Leave your computer wired to a LAN port on the WRT54G.   Power up the modem and allow it to fully boot.   Power of the WRT54G and allow it to fully boot.   Power up your computer.  Turn off the wireless adapter in your computer.  Now try to connect to the Internet.  Your system should work.  If you have a problem, temporarily turn off your computer software firewall, and try again.
If you cannot get "Reply from ..." in step 9 above, your router is likely dead.  Report back with this problem.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt.   Report back with this problem.
If you need additional help,  please state the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.  Also report what you found in steps B, C, and D.
Please let me know how things turn out for you.
