Urgent Help! I Screwed Up Very Badly

I upgraded my Windows Home Premium 7 to Windows Ultimate 7. My computer doesn't have a built in internet connector, so I have an external one that plugs-in. I tried to revert my current windows back to the old file because my Linksys AE2500 didn't have the driver. The windows disk that I have doesn't seem to work as my dog scratched it very bad, hence; I can't revert back to my orignal windows.old file. I then tried to merge my windows.old file with my windows file and all it did was destroy the windows.old file. I went to the Linksys AE2500 and downloaded the Windows 7 version 1, yet I don't know where to put this file and I'm not even sure if that will work. Can someone help me? Is there anyone way I can connect to the internet, or must I buy a new connector? Please Help!

 

Hi z0mbie, welcome to Computer Help Forums..

Do you have the disk that came with your AE2500?......or is that the disk that the dog damaged

I'm assuming the file you downloaded is a driver...if that is the case and you have the file somewhere on your computer:

Go...
Start
Right click "Computer"
Select "Properties"
Click "Device manager" (Near the top left corner)
Expand "Network Adaptors"
Double click on your device
Click the "Driver" tab
Click "Udate Driver"
Click "Browse my computer for driver software"
Navigate to where you saved the driver to

Follow any instructions given to install the new driver...
