WRT54GX2 isn't working, can't access its settings

Question

There seems to be a problem with my wireless WRT54GX2 router. It was working fine but now is not. Not only can I not access the internet when it is properly connected but I can't even reach the 192.168.1.1 settings. If I disconnect the router and connect directly to the modem and login to my SBC DSL PPPoE the internet works fine.
When the router is connected the power, internet, wireless, and LAN LEDs are all on. I have hit the reset button and it doesn't help. I have ran the router's setup CD, followed the directions, but when I reach the final step of saving the settings I eventually get the message that the router can't be found.
Any suggestions?
Thanks in advance.

You will need to try to reset your router to the factory defaults.  (Note: if you get stuck at any step, note the exact error message, and what lights on the router are on.)
Do the following:
1) Power down your computer, router, and modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Connect one computer, by wire, to LAN port 1  (not the Internet port).  DO NOT CONNECT THE MODEM.
4)  Power up the router, allow it to fully boot (1-2 minutes).
5)  Press and hold the router reset button for 20 seconds, then release the button.  Allow the router to reset and fully boot (2-3 minutes).
6)  Power down the router, and wait 2 minutes.
7)  Power up the router and allow it to fully boot (1-2 minutes).
8) Power up computer.
9)  Now, try to ping your router.  To do this, click the "Start button", select "Run".   In the box labeled "Open", type in "ping 192.168.1.1"  (no quotes), then click on "OK".   A black box will open and 3 or 4 lines will appear that start 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  
11)  Leave the user name blank, and enter the password "admin"
12)  This should take you to your router setup pages.  Note the router's firmware version.   This should be listed in the upper right hand corner of the router's web page.
13)  Close your browser.
Report back with your results, including your firmware version, and any error messages, and we will proceed to the next step.
If you get through all the steps with no errors, and all this is working, then you should be able to use your setup CD to complete the router setup.
