How to install a network interface card

Typically an Ethernet network interface is built-in to most modern motherboards. Some computer systems, especially server systems, are equipped with two network interfaces built-in to the motherboard. Additional interfaces can be installed in extra PCI expansion slots.

Try the command lspci -vv to see if the hardware is detected properly, and which kernel module (if any) is being assigned:

or more specifically lspci -vv | grep Ethernet

The network configuration tools and network configuration files are different for Ubuntu/Debian vs Red Hat/Fedora based systems.

  • sudo /etc/init.d/networking start
  • sudo /etc/init.d/networking stop
  • sudo /etc/init.d/networking restart

Ubuntu GUI network configuration tool: /usr/bin/gnome-nettool (apt-get install gnome-nettool)

One can also configure Ubuntu systems by adding entries to the configuration file:
/etc/network/interfaces

Dynamic IP: Static IP: Address and netmask are required. The system can calculate defaults for the other values.

DNS configuration will be required in /etc/resolv.conf. For this and other networking configurations see the YoLinux Networking tutorial.

The most simple method of configuring Red Hat based distributions is by using the console based GUI tool:
system-config-network

Both static and dynamic configurations can be set. If configuring for DHCP, go to that line and pres the space bar. An asterisk “*” will appear to show that this option has been selected.

After device configuration, the new device will show up in the list.

  • /sbin/ip addr show OR
  • /sbin/ifconfig

The addition and configuration of the new Ethernet device will generate the new file:
/etc/sysconfig/network-scripts/ifcfg-eth1

See /usr/share/doc/initscripts-*/sysconfig.txt for the explanation of all options.

The command ifup eth1 and ifdown eth1 are used to bring the new Ethernet interface card into service or offline.

How to install a network interface card

Short for Network Interface Card, a NIC is also commonly referred to as a network adapter and is an expansion card that enables a computer to connect to a network such as a home network and/or the Internet using a Ethernet cable with a RJ-45 connector.

This section discuss the process of installing a Network Interface Card/Network Adapter.

Installation Process in Windows

  1. First step is to read the user’s guide and familiarize yourself with the new card.
  2. Power down PC and remove the AC power cord.
  3. Open the computer case.
  4. Find an available Peripheral Component Interconnect (PCI) slot on the motherboard and remove slot insert if one exists.

This site provides a step-by-step procedure list for installing a Wired Network Adapter, both USB and PCI.

This site outlines the different ways of installing a network card in Linux depending on the Linux Distribution being used.

This site outlines the steps to installing the Network Card driver via a manufacturer CD-ROM or a manufacturer’s website.

This site is another step-by-step account of installing a network interface card using Windows and Network Wizard.

This topic describes the types of Network Interface Cards (NICs) that an NDIS miniport driver can manage, as well as how the different kinds of NICs affect the way a driver transfers network data.

Reporting a NIC’s medium type to NDIS

To report a medium type for a NIC, a miniport driver passes a pointer to an NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure in the MiniportAttributes parameter of the NdisMSetMiniportAttributes function. A miniport driver calls NdisMSetMiniportAttributes from its MiniportInitializeEx function during initialization. Miniport drivers should set the MiniportAttributes attributes after setting the registration attributes in the NDIS_MINIPORT_ADAPTER_REGISTRATION_ATTRIBUTES structure and before setting any other attributes. Setting the MiniportAttributes attributes is mandatory. The driver sets the MediaType member of the NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure to the appropriate media type when setting the MiniportAttributes attributes.

When an overlying NDIS protocol driver calls NdisOpenAdapterEx to bind to a specified miniport adapter, it provides a list of medium types on which it can operate. NDIS uses the information from the miniport driver and from the protocol driver to set up a binding. This binding provides the path for transferring network data up and down the driver stack.

Physical NICs

The steps that a miniport driver completes to initialize a miniport adapter and to send and receive network data can depend on the features of a physical device, as follows.

With NDIS-WDM NICs, such as USB-based NICs, the way the miniport driver manages memory with DMA does not matter to NDIS and is not visible to it.

Bus-master DMA NICs

These NICs can directly access host memory through an on-board DMA controller that manages the transfer of data between the network and host memory without using the host CPU.

To send, the miniport driver sets up the NIC to map the outgoing buffers. The miniport driver then causes the device to start its transfer from this memory. The NIC DMA controller transfers the data from shared system memory onto the network and interrupts the CPU when the send is complete. To receive, the DMA controller transfers incoming data to host memory before notifying the host with an interrupt.

A bus-master DMA NIC typically has an onboard ring buffer that the miniport driver maps to a set of buffers in system memory. Typically, the NIC can be programmed to efficiently handle several packets. A miniport driver that manages such a NIC typically supports multipacket sends and receives because the NIC can efficiently handle several packets and thereby improve its I/O throughput.

Nonbusmaster DMA NICs

Currently, nonbusmaster DMA NICs include the following:

System DMA NICs

A miniport driver that manages such a NIC uses the system DMA controller to manage the transfer of packet data to and from the network. Transfer of the data requires the cooperation of the host CPU.

Virtual NICs and miniports

In a virtual machine, NDIS miniport drivers can manage either software-only resources as a virtual miniport, or they can manage a virtual NIC that represents hardware resources. The following table explains the differences between a virtual miniport and a virtual NIC.

Most computers and motherboards today have a network card onboard, which means you may not need to install a network card.

How to determine the network card type

Before getting started

  1. Difficulty of installing a PC network card should be a 4 out of 5.
  2. Write down important information from the top or bottom of the card such as the Model Number, Serial Number, and specifications.
  3. Ensure you are familiar with ESD and its potential dangers.
  4. When physically installing the network card, ensure the computer is powered down and unplugged.

Set jumpers

Before installing the network card, verify that the jumpers are properly set. Today, most computers do not have jumpers for a network card installation and allow the network card to be set up and configured through software or plug and play. If available, we recommend it be used.

Install into expansion slot

Today, network cards connect to the PCI slot. Locate an available expansion slot in the computer and gently push the card into the slot until it snaps into place. Once the card is inserted, place a screw into the top of the card to hold the card into position.

If your computer has a network card already installed and you are replacing or upgrading that network card, you need to remove the existing network card before installing the new card. For further help, see: How do I remove an expansion card in my computer?

Attach internal cables

Most network cards will not include internal cables, but you may find Wake-on-LAN cable, which wakes the computer when network activity is present. If cables are included with the network card and your computer supports these cables, install the cables now.

The Wake-on-LAN cable must also be a supported feature of the computer motherboard. The cable will connect to the Wake-on-LAN or similar connection on the motherboard. Consult the motherboard documentation or manufacturer for additional information if this is a supported feature or where the cable should be connected.

Attach external cables

Once the network card is physically installed, replace the case panel and connect the keyboard, mouse, monitor, power, and network cables. Then, connect the other end of the network cable to the network outlet on a hub, switch, or router.

Software setup

Once connected, turn the computer on and install the drivers for the Network card. If you do not have drivers for your network card or the network card drivers included appear not to work, you can find links to network drivers on our network card drivers page.

Once the Network card is installed, set the configuration values for the network card in the software. These values will depend on the configuration of your network. If it is a corporate or business network, and you aren’t sure how to configure your network card, contact your network’s administrator for detailed instructions. If it is a home network, consult your router’s printed or online manual.

How to install a network interface card

Microsoft Windows users can determine the NIC (network interface card) currently installed in their computer by following the steps below.

Windows 8 and 10 users

  1. In Windows 8, start typing system info while on the Start screen and select the System Information option in the search results.

Windows 7 and earlier users

  1. Click Start and then click the Programs or All Programsoption.
  2. Click the Accessories and then the System Tools folder.
  3. In the System Tools folder, click the System Information program.
  4. In the System Information window, click the + symbol next to Components in the left navigation area.
  5. Click the + next to Network and highlight Adapter. The right side of the window should display complete information about the network card.

Microsoft may install a different, but compatible driver for some network cards. As a result, the network card listed may not actually be the exact manufacturer or model that is installed on your computer.

Other methods of determining the network card type

  1. Looking at the back of the desktop or side of a laptop, if you see an RJ-45LAN (local area network) port, the computer has an Ethernet network card.
  2. Another method of determining the network card in the computer is by physically looking at the network card. Many times the network card lists the manufacturer and part number on the actual card.
  3. If you cannot locate a manufacturer or model number of the network card, but can locate an FCC identification number, we recommend you perform an FCC search using that number. For additional information about FCC numbers, see our FCC definition page.

Product listing or specifications

If you’re trying to list all the specific information about your computer network card, specifying the manufacturer, type, model, and speed of the network card is sufficient. Below is an example of how this may look.

Drivers or installation

Replacement or repair

If you’re trying to determine the network card because it needs replaced or repaired, we recommend the network card be replaced with another network card. If you are replacing an old 10 MB network card, we recommend it be replaced with a 10/100 network card.
