I 100% stand by what
Leeky has said here! You just can't make a mad dash power grab for every network interface card driver under the sun, moon and stars. You have to be very mindful of what your trying to do here, many drivers for interface cards may come close, due to similar attributes, but even with being very similar, if the driver isn't written for your exact network card, the driver won't work. You just cant make a power grab for everything and throw it all against the wall, and see what sticks! I would strongly recommend that you take a couple minutes here and go about things in a more "hands on" way.
(1) Go to the computer in question.
(2) Go behind the computer and unplug the power cord, let it rest upon the floor.
(3) Grab an appropriate sizes screw driver and or use whatever means your computer is set for, and take the case off.
(4) Look towards the rear or back of the interior, match up the exterior RJ-45 connector to the card inside.
(5) Once located with the appropriate sized screw driver or other way, unsecure the network card and remove it from the PC.
(6) Once the card is in hand, inspect it, there should be various names and numbers on it.
(7) Once a company name and or model number is secured, jot it down on paper, all you find, jot it all down.
(8) Replace the network card back where you found it inside the computer, making sure it's secured.
(9) Replace the outer case of your computer, make sure all screws are secured and back in place.
(10) Replace the power cord, that has been resting on the floor, plug it back into your computers power supply.
(11) Proceed to a computer that has Internet connectivity.
(12) Open up a web browser, go to Goggle Search, and start inputting what you jotted down, company, model number, ect.
(13) Through the search, start targeting in on your findings, if manufacturer links to the card show up, click on that.
(14) If manufacture links showed up and you click on those, you should now find downloadable drivers for your network card.
(15) By whatever means, download the appropriate driver for your network card.
(16) Once the download is complete, use whatever medium to off load the driver from that computer.
(17) Take said driver on either USB flash drive, CD-R, ect. to the computer with the network card issue.
(18) Via the medium, go about making the computer ready for the new driver, either by "auto launch" or the "update driver"
feature located by accessing your device manager, finding the card, ((right)) clicking on it and selecting "properties.
Once the properties are being shown, select the "driver" tab button up above. You will now see and option in there
called "update driver", ((left)) click on that to accept. A directory window will now pop up, asking if it should look for the
driver automatically or should it look for the driver where you tell it to look? You will want to instruct this feature to look
for the driver where you want it to look, direct the driver search feature to the medium, USB, CD-R, CD-RW, whatever.
Tell it to look at the medium and select "ok" to accept. If successful you will see some "copying" in between Windows and
the medium, that means the driver is being copied and with luck the network card will soon be yours to use. Wait for this
process to complete. After everything is done, you will want to then confirm that this whole procedure was successful.
Go back into your "device manager" and look for your network solutions, if successful you should now see your network
in there and is now ready to use. Back out of your device manager and test things out by trying to gain access to the
Internet, if solved, you should now see whatever main web page the browser was programmed for.
I'm sure other might chime in here and either support what I've said, add onto it, or shoot it down, but if you do what I have said, you will then have your network card problem resolved.
Good luck!
