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?

In Ubuntu 18.04 and later, ifconfig is superceded with: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
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp0s25: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
