This article introduces the relevant knowledge of "how to search and display network card information on the Ubuntu system". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Want to know what network card you are using in Linux? It is easy to identify the manufacturer of the network card in Linux. Open a terminal and enter the following command:

The code is as follows:

Sudo lshw-C network

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

The code is as follows:

*-network

Description: Wireless interface

Product: BCM4360 802.11ac Wireless Network Adapter

Vendor: Broadcom Corporation

Physical id: 0

Bus info: pci@0000:03:00.0

Logical name: wlan0

Version: 03

Serial: 9c:f3:87:c1:5d:6a

Width: 64 bits

Clock: 33MHz

Capabilities: busmaster caplist ethernet physical wireless

Configuration: broadcast=yes driver=wl0 driverversion=6.30.223.248 (r487574) ip=192.168.1.23 latency=0 multicast=yes wireless=IEEE 802.11abg

Resources: irq:18 memory:b0600000-b0607fff memory:b0400000-b05fffff

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

The lshw command is actually used to list hardware, so the name of the command is lshw. With the network option, only the network hardware will be filtered out.

Other ways to learn about network cards

You can also use the lspci command to display information on the PCI bus. You should use a normal user to run this command. Just enter at the command line:

The code is as follows:

Lspci

The output of the command looks like this:

The code is as follows:

0488SS9183 PCIe SSD Controller 00.0 SATA controller: Marvell Technology Group Ltd. 88SS9183 PCIe SSD Controller (rev 14)

These commands list both wired and wireless network cards. You should notice that the output above shows that there is no wired network card in my system. Because I am using Macbook Air, it does not have an Ethernet port
