How to Find Wireless Chipset Information on CentOS/RHEL/Ubuntu Linux
This post will guide you how to check the information of currently installed WiFi drivers on your CentOS/RHEL/Ubuntu Linux system. How do I find out which WiFi driver is installed on your Linux system. How to find the hardware chipset information on CentOS Linux. How to find ou the name of my wireless chipset or interface information on Ubuntu/Debian Linux.
Find Wireless Chipset Information
You can use the lspci command to check the information of PCI buese of your computer. just type the following command to check the wireless chipset information:
$ lspci | grep -i wireless
Outputs:
devops@devops-osetc:~$ lspci | grep -i wireless
03:00.0 Network controller: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter (rev 03)
Then you can execute the following command to get the information about the wireless adapter driver:
$ lspci -vv -s 03:00.0
Or you can issue the following command to list the information of wireless chipset, type:
$ lspci -nnk | grep -A2 0280
Outputs:
08:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723AE PCIe Wireless Network Adapter [10ec:8723] Subsystem: Realtek Semiconductor Co., Ltd. Device [10ec:0724] Kernel driver in use: rtl8723ae
Find Network Wire Adapter Chipset Information
If you want to get the information of the network adapter chipset information on your Linux system, you also can use the lspci or lshw commands to achieve the result. just type the following command:
$ lshw -C network
Outputs:
devops@devops-osetc:~$ lshw -C network WARNING: you should run this program as super-user. *-network description: Ethernet interface product: 82540EM Gigabit Ethernet Controller vendor: Intel Corporation physical id: 3 bus info: pci@0000:00:03.0 logical name: enp0s3 version: 02 serial: 08:00:27:d9:84:92 size: 1Gbit/s capacity: 1Gbit/s width: 32 bits clock: 66MHz capabilities: bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=e1000 driverversion=7.3.21-k8-NAPI duplex=full ip=10.182.39.73 latency=64 link=yes mingnt=255 multicast=yes port=twisted pair speed=1Gbit/s resources: irq:19 memory:f0000000-f001ffff ioport:d010(size=8) WARNING: output may be incomplete or inaccurate, you should run this program as super-user.
From about outputs, you can find lots of information about network adapter, including description, vendor, product,driver information.
This command will give you information about both wired and wireless network adapters. As thise is no wireless adapter for my system , so the output do not print the information about wire adapter.
You can use the lspci command to get the same information about network adapter, type:
$ lspci --nnk | grep -A2 0200
Outputs:
devops@devops-osetc:~$ lspci -nnk | grep -A2 0200
00:03.0 Ethernet controller [0200]: Intel Corporation 82540EM Gigabit Ethernet Controller [8086:100e] (rev 02)
Subsystem: Intel Corporation PRO/1000 MT Desktop Adapter [8086:001e]
Kernel driver in use: e1000
Once you get the driver name that you are using in your system, and you can use the modinfo command to show more inforamation about this driver. From the above outputs, we can know that the current network adapter driver is e1000, so we can type the following command to get more detailed information about this driver:
$ modinfo e1000
Outputs:
devops@devops-osetc:~$ modinfo e1000 filename: /lib/modules/4.8.0-36-generic/kernel/drivers/net/ethernet/intel/e1000/e1000.ko version: 7.3.21-k8-NAPI license: GPL description: Intel(R) PRO/1000 Network Driver author: Intel Corporation, <linux.nics@intel.com> srcversion: A2CE8CF7D2BAFE382A1AB61 alias: pci:v00008086d00002E6Esv*sd*bc*sc*i* alias: pci:v00008086d000010B5sv*sd*bc*sc*i* alias: pci:v00008086d00001099sv*sd*bc*sc*i* alias: pci:v00008086d0000108Asv*sd*bc*sc*i* alias: pci:v00008086d0000107Csv*sd*bc*sc*i* alias: pci:v00008086d0000107Bsv*sd*bc*sc*i* alias: pci:v00008086d0000107Asv*sd*bc*sc*i* alias: pci:v00008086d00001079sv*sd*bc*sc*i* alias: pci:v00008086d00001078sv*sd*bc*sc*i* alias: pci:v00008086d00001077sv*sd*bc*sc*i* alias: pci:v00008086d00001076sv*sd*bc*sc*i* alias: pci:v00008086d00001075sv*sd*bc*sc*i* alias: pci:v00008086d00001028sv*sd*bc*sc*i* alias: pci:v00008086d00001027sv*sd*bc*sc*i* alias: pci:v00008086d00001026sv*sd*bc*sc*i* alias: pci:v00008086d0000101Esv*sd*bc*sc*i* alias: pci:v00008086d0000101Dsv*sd*bc*sc*i* alias: pci:v00008086d0000101Asv*sd*bc*sc*i* alias: pci:v00008086d00001019sv*sd*bc*sc*i* alias: pci:v00008086d00001018sv*sd*bc*sc*i* alias: pci:v00008086d00001017sv*sd*bc*sc*i* alias: pci:v00008086d00001016sv*sd*bc*sc*i* alias: pci:v00008086d00001015sv*sd*bc*sc*i* alias: pci:v00008086d00001014sv*sd*bc*sc*i* alias: pci:v00008086d00001013sv*sd*bc*sc*i* alias: pci:v00008086d00001012sv*sd*bc*sc*i* alias: pci:v00008086d00001011sv*sd*bc*sc*i* alias: pci:v00008086d00001010sv*sd*bc*sc*i* alias: pci:v00008086d0000100Fsv*sd*bc*sc*i* alias: pci:v00008086d0000100Esv*sd*bc*sc*i* alias: pci:v00008086d0000100Dsv*sd*bc*sc*i* alias: pci:v00008086d0000100Csv*sd*bc*sc*i* alias: pci:v00008086d00001009sv*sd*bc*sc*i* alias: pci:v00008086d00001008sv*sd*bc*sc*i* alias: pci:v00008086d00001004sv*sd*bc*sc*i* alias: pci:v00008086d00001001sv*sd*bc*sc*i* alias: pci:v00008086d00001000sv*sd*bc*sc*i* depends: intree: Y vermagic: 4.8.0-36-generic SMP mod_unload modversions parm: TxDescriptors:Number of transmit descriptors (array of int) parm: RxDescriptors:Number of receive descriptors (array of int) parm: Speed:Speed setting (array of int) parm: Duplex:Duplex setting (array of int) parm: AutoNeg:Advertised auto-negotiation setting (array of int) parm: FlowControl:Flow Control setting (array of int) parm: XsumRX:Disable or enable Receive Checksum offload (array of int) parm: TxIntDelay:Transmit Interrupt Delay (array of int) parm: TxAbsIntDelay:Transmit Absolute Interrupt Delay (array of int) parm: RxIntDelay:Receive Interrupt Delay (array of int) parm: RxAbsIntDelay:Receive Absolute Interrupt Delay (array of int) parm: InterruptThrottleRate:Interrupt Throttling Rate (array of int) parm: SmartPowerDownEnable:Enable PHY smart power down (array of int) parm: copybreak:Maximum size of packet that is copied to a new buffer on receive (uint) parm: debug:Debug level (0=none,...,16=all) (int) devops@devops-osetc:~$
