Question

Hello all! I've been having a serious issue with my WRT54G2 Router as of late and have had many reccomendations on how to fix it but nothing has worked. I'm going to post just about every interaction I've had on there boards to date.  Any more help would be much appreciated. I'm getting desperate.

I'm using a WRT54G2 Router.  It's wired to a Motorola Surfboard modem.  I can't access the manual config 192.168.1.1 and two other computers that are wireless in the house rely on my access point to be able to use the internet. Problem is I'm getting that good o'l "You are connected to the access point, but the internet cannot be found."  I've tried assigning static IP's, power cycling, release/renew in IPCONFIG,  I've whispered sweet nothings into my PC's ear...etc...etc...etc... I CAN access the manual config through the one laptop when it's wired to the modem though. Please for the love of everything someone help me!!!!!
Here's what IPCONFIG /ALL says about my computer.

Are you trying to access 192.168.1.1  wirelessly?   If so, stop doing this.  Wireless access to 192.168.1.1  often fails.  Use a computer that is wired to the router when you want to change router settings.
1)  I assume that the "IPCONFIG /ALL"  info that you posted was obtained when your computer was wired directly to your modem  --  is that correct?
2)  When you did the "IPCONFIG /ALL", was your computer wired to the modem with ethernet cable, or USB cable?
3)  Your network should be setup like this:
Motorola Surfboard -- WRT54G2  )))     ((( wireless computer(s)
                                    |--- wired computer
Motorola Surfboard ethernet port wired to WRT54G2 Internet port, using ethernet cable.
Wired computer connected to a LAN port on the WRT54G2, using ethernet cable.
Nothing connected to USB port of Motorola Surfboard.
Wireless computers connect directly (and wirelessly) to WRT54G2, not to your wired computer.
Is above the way your system is setup?  If not, how is your system setup? 
4)  Please clarify the problem that you are having.  Are you saying that your computer simply cannot access 192.168.1.1 , or that it cannot access the Internet, or that you cannot get any of your computers to access the Internet through the WRT54G2?    Are you trying to connect this computer by wire or wirelessly to the WRT54G2?
5)  Can any computer access the Internet through the WRT54G2?

No, I'm trying to acess it through a wired computer. The computer I'm on right now is wired to the access point which is wired to the motorola modem. I can access the login page(as well as the internet) through the computer wired to the router(which, as stated just a few sentences ago, I'm currently using), but when i type in admin for the password it literally kicks me right back into the login screen with both username and password feilds blank. My entire system is setup the way you described that it should be ethernet cable and all. Trust me that was the first thing I checked. The IPCONFIG /ALL is the status of the computer wired to the router. The other two computers in the house (one is a laptop with wireless card and the other is a PC that I bought a wireless card for) cannot access the internet. They used to be able to until recently and I've made no changes to any of the settings.
I also tryed power cycling the system. It granted wireless access to the wireless computers as well as my playstation 3, BUT, I lost internet access on the wired computer. Imagine my frustration. I power cycled again then I was back to square one. No wireless access but access with the wired pc. It's not set to a static IP address either.

D)  Have you upgraded the router's firmware?
E)  After the firmware upgrade, did you reset the router to factory defaults, then setup the router again from scratch?
F)  You said that the "IPCONFIG /ALL" was obtained when you were connected to the WRT54G2 router.  But this looks like IPCONFIG data from connection to the Motorola Surfboard modem.  Are you sure this IPCONFIG /ALL is from connection to the WRT54G2?
G)  Have you been running unsecured wireless?   Or are you using encryption?  If you are using unsecured wireless, perhaps your neighbor logged into your router (by accident or intentionally) and changed your login password.
I would suggest that you reset your router to factory defaults, then setup the router again from scratch.  If you saved a router configuration file, DO NOT use it.
Please use the following procedure to reset your router:
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, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
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.
Please let me know how things turn out for you.

My apologies for the delay in response, things have been hectic lately.  Alrighty, I did all that you said and here are some interesting results, I'll break down the results by each machine that a fiddled with:
Wired Desktop PC:
-I got no response when trying to ping the router
-Could not access the 192.168.1.1 configuration screen, not even the prompt for username and password
-When using the installation disk AND the installation program i downloaded off the Linksys website it would not detect the router.
Wireless Laptop(this is where i think it gets interesting):
-I was able to fully install and automatically configure the router by using the installation disk
-I could ping and get full response from the router both wirelessly and while it was directly wired to the router
-I could also access the configuration menu 192.168.1.1 in my web browser
-I also had a backup copy of the latest firmware for the router on my flash drive, so I updated the firmware through the laptop.
-The laptop was using the router as it's access point, however the internet could not be found.
If I wasn't at a total loss before I tried all this, I certainly am now. Could it be a problem with the network settings on the PC that is wired? Perhaps a faulty ethernet port? Your thoughts?
Well, that's where it left off, I got no responses back from anyone after the last post. Help!!!

Answer 1

As you are able to access your router's web interface you should now try to re-configure it...
