2 ethernet connection error

Question

I am installing a new WRT54G on my computer. Followed all the instructions on disk for the connections for computer to my Surfboard cable modem to the router. When it tries to read the router, it doesn't read it. What happens is I lose my internet connection. The error pops up that I have 2 ethernet connections open. This is my first and only ethernet that i know of. What's the problem?

Answer 1

Your router should work when set to its factory default settings.
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.
If you get this far without problems, power down the computer and router.   Using an ethernet cable, wire the ethernet port on the modem to the Internet port on the router.  Leave the computer wired to LAN port 1 on the router.   Power up the modem and allow it to fully boot (1-5 minutes).  Power up the router and allow it to fully boot (1-2 minutes).  Power up your computer.  Test your Internet connection.  It should work.
If you cannot get "Reply from ..." in step 9 above, your router is dead.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you.
