Before doing any of that, I recommend as root dmesg|grep -i wlan <cr>.
Some of these systems like to rename wlan0 and give it strange names and
this way you know what that name is and don't waste time.

Hi, Willem here.
I have not used wpa_cli, but if your /etc/wpa_supplicant/wpa_supplicant.conf
has a valid network block, you can look at your /etc/network/interfaces to
see what the entry for wlan0 looks like and then take it from there.
By the sound of it, you might not have a configuration for wlan0 in there.
If so, add something like the below to /etc/network/interfaces and then try
ifup wlan0
iface wlan0 inet dhcp
pre-up wpa_supplicant -iwlan0 -B -c/etc/wpa_supplicant/wpa_supplicant.conf
post-down killall -q wpa_supplicant
auto wlan0
HTH, Willem

Following the guide at
https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md,
I successfully got my Raspberry Pi 3 running a near stock Raspbian
Stretch Lite connected to my wireless network. Copying
/etc/wpa_supplicant/wpa_supplicant.conf and running wpa_cli -i wlan0
reconfigure, I repeated this on my Raspbery Pi 2 using a USB Wi-Fi
dongle without any effort.
Now, I'm trying to repeat this on a desktop that has Wi-Fi onboard
with much less success. I installed wpasupplicant and wireless-tools
via Aptitude, copied over the wpa_supplicant.conf file, and ran
wpa_cli -i wlan0 reconfigure to recieve the following error message:
Failed to connect to non-global ctrl_ifname: wlan0 error: No such
file or directory
And running iwconfig produces the following output:
wlan0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:off
Neither of which is all that helpful, especially since the above
mentioned successes with Raspberry Pis are the only successes I've
ever had connecting a Linux machine to a wireless network.
So, any ideas as to what I'm doing wrong?
