How to find available network adapters on Ubuntu

Do you want to know what Nic you are using in Linux? In Linux, it is easy to find the network card manufacturer. Open a terminal and enter the following command: sudolshw-Cnetwork if the command above cannot be used in sudo, do not use sudo's privileged mode. Its output looks strange but useful. *-Networkdescription: Wirelessinterfaceproduct: BCM

Want to knowWhat is the network adapter you are using in Linux?In Linux, it is easy to find the network card manufacturer. Open a terminal and enter the following command:

1. Sudo lshw-C network

If the above command cannot be used in sudo, do not use sudo's privileged mode. Its output looks strange but useful.

1. *-Network
2. Description: Wirelessinterface
3. Product: BCM4360 802.11 acWirelessNetworkAdapter
4. Vendor: BroadcomCorporation
5. Physical id: 0
6. Bus info: pci @ 3::0:00. 0
7. Logical name: wlan0
8. Version: 03
9. Serial: 9c: f3: 87: c1: 5d: 6a
10. Width: 64 bits
11. Clock: 33 MHz
12. Capabilities: busmaster caplist ethernet physical wireless
13. Configuration: broadcast = yes driver = wl0 driverversion = 6.30.223.248 (r487574) ip = 192.168.1.23 latency = 0 multicast = yes wireless = IEEE 802.11abg
14. Resources: irq: 18 memory: b0600000-b0607fff memory: b0400000-b05fffff

As you can see, the wireless network card on my Macbook Air is BCM4360, which is a network card that is easy to detect wireless network problems under Ubuntu.

The lshw command is actually used to list hardware. Therefore, the command name is lshw. With the Network option, only the network hardware is filtered out.

In addition, you can use the lspci command to display information on the PCI bus. You should not run this command in privileged mode. Enter the following command line:

1. Lspci

The command output looks like this:

These commands list both wired and wireless NICs. You should note that the above output shows that my system does not have a wired Nic. Because I use a Macbook Air, it does not have an Ethernet port.

I hope this article will help you find the network card in your system. You are welcome to raise questions and suggestions.
