To know the manufacturer of the network adapter of your computer in Linux, type this command in terminal:
sudo lshw -C network
The output of the command may look something like this:
*-network description: Wireless interface product: BCM4313 802.11b/g/n Wireless LAN Controller vendor: Broadcom Corporation physical id: 0 bus info: [email protected]:03:00.0 logical name: wlan0 version: 01 serial: 70:f1:a1:c2:f2:e9 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=brcm80211 driverversion=2.6.38-8-generic firmware=N/A ip=172.17.4.253 latency=0 link=yes multicast=yes wireless=IEEE 802.11bgn resources: irq:17 memory:f0500000-f0503fff *-network description: Ethernet interface product: AR8152 v1.1 Fast Ethernet vendor: Atheros Communications physical id: 0 bus info: [email protected]:04:00.0 logical name: eth0 version: c1 serial: b8:ac:6f:67:11:46 capacity: 100Mbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress vpd bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=atl1c driverversion=22.214.171.124-NAPI firmware=N/A latency=0 link=no multicast=yes port=twisted pair resources: irq:43 memory:f0400000-f043ffff ioport:2000(size=128)
Check the output closely. It gives information about both Wired and Wireless Network Adapter. No need to specify that one with Wireless Interface describes wireless adapter and one with Ethernet Interface describes Wired Network Adapter. As you can see in the output, I have Broadcom’s wireless adapter and Atheros Ethernet (wired) adapter.
