It appears this is a common topic but I think my problem may be unique in that I cannot find ifconfig. I was trying to follow this tutorial and others. I am on Ubuntu 18.04 and Windows 10. When I type

ifcongig

This is what I see. 

Command 'ifconfig' not found, but can be installed with: sudo apt install net-tools

It sounds as though I need to do a reinstall, this time getting these default programs included so I can get wifi. Does anyone have any suggestions as to how I might get these default appications?

  • ifconfig is no longer bundled with Ubuntu, but you can install it with apt as suggested in the error output. But you can also switch to the current software, ip. See man ip to learn how to use it. Example: ip a – sudodus Nov 27 '18 at 16:07

In Ubuntu 18.04 and later, ifconfig is superceded with:

ip addr show

Here is a sample output:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    inet6 ::1/128 scope host
