What and How to install Ethernet adapter drivers
I’m currently trying to set a computer with Ubuntu Server (version: 16.04.3). I believe the drivers for the wireless adapter are installed, but I need the iwconfig utility/command to configure it. But in order to get iwconfig , I need an internet connection. I’ve decided to temporarily enable ICS (Internet Connection Sharing) on the Ethernet port of my Windows 7 computer, but now I’m having trouble getting an internet connection over the Ethernet connection (between the Windows computer and the Ubuntu Server computer). Here’s the output for sudo lshw -c network :
*-network UNCLAIMED description: Ethernet controller product: Qualcomm Atheros vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:05:00.0 version: 10 width: 64 bits clock: 33MHz capabilities: pm pciexpress msi msix bus_master cap_list configuration: latency=0 resources: memory:ef100000-ef13ffff ioport:e000(size=128) *-network DISABLED description: Wireless interface product: RTL8192EE PCIe Wireless Network Adapter vendor: Realtek Semiconductor Co., Ltd. physical id: 0 bus info: pci@0000:08:00.0 logical name: wlp8s0 version: 00 serial: 7c:8b:ca:0a:03:34 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=rtl8192ee driverversion=4.4.0-87-generic firmware=N/A latency=0 link=no multicast=yes wireless=IEEE 802.11bgn resources: irq:132 ioport:d000(size=256) memory:ef000000-ef003fff From some digging online, the UNCLAIMED status leads me to believe that a driver is not installed for or not associated with the Ethernet adapter. Am I correct? How do I figure out which driver is needed? How do I acquire that driver (if it’s not already installed)? How do I set up / associate the driver with my device? Here’s the output for sudo lspci -nn | grep eth :

How to find network card driver name and version on Linux
Question: An Ethernet network interface card is attached to my Linux box, and I would like to know which network adapter driver is installed for the NIC hardware. Is there a way to find out the name and version of a network card driver for my network card?
For network interface card (NIC) hardware to operate properly, you need a suitable device driver for the NIC hardware (e.g., ixgbe driver for Intel NICs). A NIC device driver implements a hardware-independent common interface between the Linux kernel and the NIC, so that packets can be moved between the kernel and the NIC. While some drivers may be statically built in the kernel, most drivers for modern NICs are dynamically loaded as kernel modules.
When you are troubleshooting a NIC hardware problem, one thing you can do is to check whether a correct network adapter driver is installed properly. In this case, you need to know which kernel module is your NIC driver.
There are several ways to find the name/version of an Ethernet card driver on Linux.
Method One: dmesg
The first method is to to check dmesg messages. Since the kernel loads necessary hardware drivers during boot, dmesg output should tell if an Ethernet card driver is installed.
The above output shows that a driver named tg3 is loaded in the kernel.
If you want to know more detail about this driver (e.g., driver version), you can use modinfo command.
If dmesg does not print any information about Ethernet driver, that means no suitable network device driver is available on your system.
Method Two: ethtool
The second method is to use the ethtool command. To find out the driver name for an interface eth0 , run the following.
Method Three: lshw
Another useful tool for NIC driver information is lshw . Type the following command to get detailed information about available Ethernet card(s) and their driver.
In the lshw output, look for the capabilities line, and examine driver and driverversion in the line.
If no suitable NIC driver is installed on your system, the driver field will remain empty.
