Is that correct? The wpa_cli command syntax is: password configure password for an SSID However, I'm not sure == SSID. When you add a network in interactive mode with: add_network the shell outputs a network id number; e.g. 3, which you are meant to use thereafter to set up variables for the AP; e.g.: set_network 3 ssid "starvebux" set_network 3 psk "Not Free" enable_network 3 In addition, I understand the wpa_cli command 'password', as opposed to variable 'psk' which is used in the interactive shell, to be for a EAP-PEAP authentication scheme. For a pre-shared key you'll use interactively: set_network 3 psk 0f0fbfdadff6271a5107a49cfb5db9e921138ee74a66b0. or if it is a passphrase you'll enclose it in double quotes "Not Free" as above. This is the reason I use the wpa_supplicant GUI when not restricted to working in a console, because the qt5 wpa_supplicant GUI makes it easier to click and fill in a PSK, compared to the multiple commands required in a terminal. signature.asc Description: This is a digitally signed message part.

During launch, wpa_supplicant blows up on... DIR=/var/run/wpa_supplicant GROUP=wheel DIR=/var/run/wpa_supplicant GROUP=0 https://wiki.gentoo.org/wiki/Wpa_supplicant#Configuration recommends... ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel The 3 lines in my wpa_supplicant.conf that are not commented out are... ctrl_interface_group=0 ap_scan=1 ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=wheel Thank you for your help. It works. I live in a condo building. As a regular user "wpa_cli scan" followed by "wpa_cli scan_result" shows approximately a couple of dozen machines. BTW I've disabled MVM and wifi still works. One last question; I occasionally see signs in various places saying Our network name is "foo" and password is "bar". My reading of the wpa_cli man page indicates I should use... wpa_cli password foo bar ...to log on. Is that correct? -- Walter Dnes I don't run "desktop environments"; I run useful applications

If you have enabled the wheel group and your user is a member of this group,
then you won't need to run things as root:
DIR=/var/run/wpa_supplicant GROUP=wheel
DIR=/var/run/wpa_supplicant GROUP=0
# (group can be either group name or gid)
Alternatively, you can add your users gid instead.

To state the obvious, this shows your key is not accepted:
nl80211: set_key failed; err=-22 Invalid argument
Also I can see:
key_len=0
Does this message mean you are using no passwd authentication? If so you have
to state explicitly:
set_network 0 key_mgmt NONE
in wpa_cli when you try to authenticate with your AP, or in /etc/
wpa_supplicant/wpa_supplicant.conf add a fall back configuration at the end of
the file for all open APs:
network={
key_mgmt=NONE
}
You can add BSSID, SSID to the above if you only want to use no authentication
with a specific AP rather than anything which might be within range.
BTW, key and passphrase are not the same thing. A passphrase must be entered
in quotations, or use wpa_passphrase to generate the preshared key from it:
~ $ wpa_passphrase MY_SSID "My secret passphrase"
network={
ssid="MY_SSID"
#psk="My secret passphrase"
psk=f90ff73cefa452385366f5278f64914fa832b61a5225d3c78dcd4291061b56a1

I'm having problems, even running as root. As per the previous message, the system is detecting the hardware, but wpa_aupplicant cannot get going. I have a minimal /etc/wpa_supplicant/wpa_supplicant.conf ctrl_interface=/var/run/wpa_supplicant update_config=1 From https://wiki.gentoo.org/wiki/Wpa_supplicant#Using_wpa_cli the command for debugging is... wpa_supplicant -Dnl80211 -iwlan0 -C/var/run/wpa_supplicant/ -c/etc/wpa_supplicant/wpa_supplicant.conf -dd ...to which I appended ">>logfile.txt 2>&1" to grab all output.

If you have emerged wpa_supplicant with USE="qt5" you will have a GUI to launch its client and click on Scan to find and select a desired AP. If not, you can run wpa_cli in a terminal. Something like 'wpa_cli scan' and 'wpa_cli scan_results' should show you what's available. If you run just 'wpa_cli' it will launch an interactive shell from which you can run: > scan > scan_results 'wpa_cli --help' for more subcommands and options. > 2) how do I connect to one of the listed networks (assuming either > it's public, or I have the password) ? With wpa_supplicant's GUI, or with wpa_cli, but the latter is more tedious. Run wpa_cli to get an interactive shell.
