Welcome to Geeks to Go
Lets hope for a second your driver is installed...
Click:
Start> Control panel> Network connections> locate the "icon" for your Ethernet, and make sure it is not disabled... if this doesn't work
Click on the
"windows" button and Pause\break the same way you would
CTRL-ALT-DEL.Now click
on the
Hardware Tab> Device Manager> Then scroll down to network connections
Do you see any ? marks or ! in red or yellow color? If so and they are located over your Ethernet "connection" then there is an issue with the driver, You may be able to "roll back" the driver, or it may say there is not one installed at which point follow the instructions below...
If you don't have the driver installed:
A. Find the Drivers CD your computer came with and install it.
B. If your computer is a name brand (Dell,Hp,etc...) go to their site and download the drivers...
1.Otherwise go to the manufacture of the motherboard in your computer...
If you don't have the CD and you can't find the site to download the drivers, or need help finding your manufacture of the mobo, write back and I will assist you further...
Good luck
