To check a network adapter, determine if it’s internal or external and wired or wireless. Use the operating system or software to check and fix minor problems. Virtual adapters exist only in software. Troubleshoot by checking cables, restarting, or contacting a technician.
There are many types of network adapters, including wireless network adapters and virtual network adapters. To check a network card, you first need to determine if the type of card you’re using is internal or external, and whether it’s wired or wireless. Checking the network adapter can often be done through the computer’s operating system or through the software installed on the computer. You may also need to verify that the hardware and any cables or wires are connected correctly.
External adapters are the easiest to find and control, because they’re usually connected to a computer through a universal serial bus (USB) or other type of external port. Once you find it, you can determine if the external network adapter is a wired or wireless adapter by checking for any open connections. If the external adapter has a port for plugging in an Ethernet cable, then it’s a wired adapter. If there isn’t a port open, it’s usually a wireless adapter.
Internal network adapters can be slightly more troublesome to find and check. For an internal wired network adapter, there will be a port for connecting an Ethernet cable. Internal wireless network adapters will not have such visible signs.
It is often possible to control a network card through the operating system itself. The specific method varies between operating systems, but is usually found under the heading “Network Connections” or something similar. Many operating systems have software that can check a network card and fix minor problems, and you can usually do this by simply clicking an option within your computer’s control center. Sometimes, a problem can be resolved by having the operating system reset the network adapter. If you’re having trouble figuring out how to get your operating system repaired or reset your network card, be sure to read the instruction manual, search your operating system’s “Help” function, or contact your system manufacturer’s customer service center operating or network adapter.
Your computer may be using a virtual network adapter. These adapters are mostly used in virtual private networks (VPNs) to create secure connections between remote computers. These types of adapters exist only within computer software. If you have a persistent problem with a virtual network adapter, you may need to contact a computer technician or the company that created that virtual network adapter.
If you are still having problems with a hardware network adapter, there are a few additional steps you can take to attempt to resolve the issue. For wired connections, you should make sure all cables are connected properly. For wireless connections, you should check your wireless router to make sure the device is turned on and connected to the Internet. As a last step, restarting your computer sometimes resolves software conflicts that may be preventing your network card from working properly.
When all else fails, contact a computer technician to examine your computer. Many computer users will attempt to open and replace or repair parts on their own. This will often void any warranty on the computer. When someone needs to check a network card at the hardware level, a certified computer technician is almost always your best bet.
