A network driver is software that controls a device connecting a computer to a network, providing user feedback and converting information into usable formats. It acts as an interface between the operating system and hardware, abstracting technical differences. Updating and troubleshooting network drivers is important for stability and security.
A network driver is a software program that controls a device used to connect a computer to a network.
Network drivers control the interface between a computer and a given network. It is familiar with the protocol used by the computer network, creating a unique identification for the computer that can be used in the system. As information is exchanged between your computer and the network, the network driver converts it into usable formats. The network driver also provides user feedback on the state of the network so people know at all times when they are connected, at what speed and if there are problems with the network.
Computers can have one or more network devices, including wireless cards or wired Ethernet cards, for example. Without network drivers, these devices cannot function properly and may have problems accessing the network or executing user commands.
What does a network driver do?
Many people wonder what the main function of network drivers is. In general terms, any device driver acts as an interface between the “abstract” view of the hardware that the operating system has and the “physical” chipset that actually exists on the board. This layer of abstraction allows you to use different hardware from different vendors on many different operating systems. It also allows you to implement “software” devices (such as a network loopback device) that have no underlying hardware to control.
Each network chip will have different I/O registers, memory-mapped buffers, interface speed sensing modes, and all sorts of other fundamental technical differences. The driver’s job is simply to abstract these differences so that the operating system has a common API for moving packets from higher network layers to hardware (and vice versa).
Did you know?
A network driver is software that enables the transmission and reception of data on a network. Provides the data link protocol (Ethernet, Token Ring, etc.) that controls the specific brand of network adapter installed in your computer.
Network adapters are different from drivers, being hardware components that connect computers to networks via an integrated chipset, system on chip (SoC), or other suitable connection.
Most modern devices require drivers to work properly, including printers, video adapters, digital cameras, and computer storage devices such as CD-ROMs and floppy disk buses.
Device drivers, especially on modern Microsoft Windows platforms, can run in kernel mode (Ring 0 on x86 CPUs) or user mode (Ring 3 on x86 CPUs), the latter of which can help improve stability.
Network drivers play a key role in network management.
How do I find the current version of the network driver?
Identifying the current network adapter driver version on Windows 10 is a quick and easy process. From Device Manager, open the network adapter drop-down list and right-click the device you want to check. Click Properties, then the Driver tab to view the driver version. You may also see an option on this screen to update your device driver, which is a painless way to make sure your device drivers are always up-to-date.
When Should You Update Your Network Drivers?
We recommend that you update your network drivers when new software versions are released. These new releases can address security and device vulnerabilities that might otherwise become a problem for computer users, as well as expand functionality as much as the device allows. Users who are not sure whether or not they are using the latest driver can usually explore the network device properties to see which version of the driver software it is using and compare this information with the data available on the manufacturer’s website.
How do I install a network driver?
While many people may feel intimidated by the idea of installing network drivers themselves, the process is generally the same for all network devices and shouldn’t be mistaken as difficult. Once you know how to update your drivers, you’ll be better able to troubleshoot potential problems that may occur down the road.
Here’s what you need to do:
Locate and download the appropriate network adapter driver software for the device you are trying to get working properly. Most often, this can be found on the manufacturer’s website.
Find the driver installation file (probably in the “Downloads” folder) and double-click to open it. In most cases, an installation wizard will run and you just need to follow the on-screen instructions to complete the installation.
Then, click Start > Control Panel > System and Security > Device Manager.
Click on the “+” symbol next to “Network adapters”. If the installation was successful, you’ll see your network adapter listed here with an exclamation mark next to it.
From here, you can also manually update your device drivers via a zip file by clicking “Update Driver Software” and running driver update.
Network driver testing and troubleshooting
It is not uncommon for devices to conflict with each other, resulting in poor network access or stability. To test and troubleshoot the network driver, go to Control Panel > System and Maintenance > System > Device Manager > Network Adapters. From here, you’ll have a list of the drivers for your network cards and their properties, which you can right-click to view. Make sure the correct drivers are enabled and that there are no conflicts, which can also help you identify whether or not you might have a hardware problem on your hands, such as a faulty network card.
Network drivers play a crucial role in today’s increasingly interconnected digital world. By keeping your drivers updated regularly, you can ensure uninterrupted connectivity and a more enjoyable browsing experience.
