I have no ethernet controller driver for the windows 7 ultimate
The drivers that you need for devices such as sound, video, ethernet, etc. Are usually contained on a driver CD that was shipped from the manufacturer with the device. If the device is built into the motherboard, the drivers will be on a CD that was provided with the computer. If you do not have this CD, you will have to visit either the website of the manufacturer who made the motherboard, or the website of the company who made the computer to download the drivers that you need.
Once you get to the website, look in the support or downloads section of the site for the model number of your computer (or the model number of the motherboard or plug-in device).and select the drivers you need for download.
In the event that you cannot locate the driver(s), look for a "contact us" link on the website support or home page. This link will provide you with contact information (phone or E-mail) and allow you communicate your problem to them.
