The three interfaces side-by-side:
1394 or Firewire as it is commonly referred to is NOT I can assure you used for an ethernet connection and the ethernet connection is what is used for a broadband connection from the computer to the modem/router.
1394 connection showing on XP in Network Connections simply means that the computer has a Firewire port, either on an add-on card or on the I/O plate, that is the place on the rear of the tower where the mouse, keyboard and monitor (unless it has a separate graphics card) and the ETHERNET and USB connections are.
Basically the 1394 connection is a way of connecting another computer, that also has a firewire connection and was commonly used for cameras and other items. IT IS NOT used for a broadband internet connection.
So when you say
Ok, I just checked my other desktop right next to the one that's not working and it uses the 1394 adapter to connect! along with the Local connection.
I can assure you, that you are wrong in your assumption. It is shown, but it is NOT used.
The simple test for you to assure yourself that I am correct is to check yourself using the image above.
I will be extremely surprised if you have a cable connnected to the 1394 port.
Also if you go to the computer that you say uses THIS and the ethernet connection and in Network connections, you right click the 1394 connection and if DISABLE appears on the menu, click that.
If ENABLE appears then it is already disabled.
If it is disabled it is NOT being used.
If it is enabled and you disable it, you will find that the connection still works the same as it did. The only exception to this is if you have the most unusual arrangement of connecting.
NOW to the issue in hand
1. Go to device manager, right click the entry for the VIA RHINE 11 Fast Ethernet, click UNINSTALL, reboot the computer.
Watch to see if it has found new hardware and is installing the driver.
Post any details of any message indicating failure.
NOTE PLEASE
I am unsure NOW as to what cable you have connected and which you have disconnected. IF YOU DO NOT HAVE the ethernet cable connected from the computer to the modem/router, please CONNECT IT BEFORE uninstalling and rebooting the computer
NOW go to network connections and what is then shown please.
If the VIA RHINE connection is now shown test the internet connection.
IF the connection is still not shown in Network connections - proceed as below please
2. ONBOARD LAN, in otherwords the VIA RHINE may be enabled or diabled in BIOS, on booting the computer and on the POST SCREEN, it will very likely say to enter setup key F2, Delete or another key.
As soon as you see that message do so.
If it does not enter setup that time, reboot and now you know the key to press, do so immediately you see the post screen
When you get into the BIOS setup, find the screen showing
ENABLE ONBOARD LAN.
If it is ENABLED there is nothing to do, simply exit which is F10 usually. MAKE NO OTHER CHANGES
If it is DISABLED, click as shown on the right of the screen, and then select ENABLED from the options.
Again exit by using F10 - which is normally SAVE and EXIT.
The Bios screen will tell you.
DO NOT MAKE any other changes please.
IF IT WAS disabled, althougn I VERY MUCH doubt that it will have been so, reboot and check again what is shown in Network connections.
IF having done both the VIA RHINE is stil not shown in network connections proceed as below please.
3. Go start, in run type
msinfo32
when that opens
It should be on the system summary page, click edit, click select all, click edit, click copy, minimise that window, then open a word document and right click on the blank document and click paste, save the doument.
Now go back to that first window, that you minimised
on the left pane click to expand components, click to expand network, click adaptor.
when that opens, click edit, click select all, click edit, click copy, open a word document and click paste., in otherwords do the same as before
Do the same please on problem devices.
Then send me those pasted results by copying to a flash pen and attaching the actual copy and paste of the results to your reply.
Also attach to that reply, please the make and full model of the desktop if it is branded.
ie: Dell Optiplex 390 - or whatever it is.
