[gentoo-user] Problem logging on to wifi

[Walter Dnes]

  Here are the first 4 lines from scan_result at an establishment.  I've
replaced the 3-word ccompany name with "AAAA BBBB CCCC".  Note that they
share the same bssids with "BELL342".

Selected interface 'wlan0'
bssid / frequency / signal level / flags / ssid
26:20:c7:c2:b7:a7       5220    -53     [WPA2-PSK-CCMP][ESS]    AAAA BBBB CCCC
24:20:c7:c2:b7:a7       5220    -53     [WPA2-PSK-CCMP][ESS]    BELL342
24:20:c7:c2:b7:a6       2462    -28     [WPA2-PSK-CCMP][ESS]    BELL342
26:20:c7:c2:b7:a6       2462    -46     [WPA2-PSK-CCMP][ESS]    AAAA BBBB CCCC

  I've tried...

wpa_cli password "AAAA BBBB CCCC" <password>
wpa_cli password AAAA\ BBBB\ CCCC <password>

...and they both return "FAIL".  Any ideas on what to try next?

You could try:

wpa_cli add_network "AAAA BBBB CCCC" 

which will return a 'network id'; e.g. 0 if your wpa_supplicant.conf is empty 
and has no AP configured in it.  Then use this 'network id' number to specify 
a password:

wpa_cli password 0 "blah-blah"

or

wpa_cli password 0 '"blah-blah"'

NOTE:  Either the "AAAA BBBB CCCC", or the "BELL342" SSID may be for non-
public users and it could reject your attempts to authenticate if your device 
is not whitelisted, so try the other SSID if one of them won't work.

  PEBKAC.  I was mis-reading the instructions.  Since the sign at the
breakfast place mentioned "password", in the wpa_cli dialogue I entered...

> set password 0 "AAAA BBBB CCCC" "password"

...when I should've been entering...

> set_network 0 ssid "AAAA BBBB CCCC"
> set_network 0 psk "password"

  The flags "[WPA2-PSK-CCMP][ESS]" should've been the hint.
https://wiki.archlinux.org/title/wpa_supplicant#Connecting_with_wpa_passphrase
set me straight.  BTW, wpa_cli is "the hard way" of doing things.  What's
"the easy way", you ask?  It's a short script like so...

#!/bin/bash
/etc/init.d/wpa_supplicant stop
wpa_supplicant -B -i wlan0 -c <(wpa_passphrase "ssid" "password")

  No need for a stanza in wpa_supplicant.conf.  Note: *THE SCRIPT MUST
BE RUN FROM A ROOT SHELL.  "SUDO" WILL NOT WORK.*   The "wpa_passphrase"
tool is installed as part of "wpa_cli" install, no extra setup needed.

  I was the first customer in for breakfast, so I had the wifi network
capacity all to myself.  https://www.speedtest.net/result/13728930233
is the result from Speedtest Net, over 31 mbits down and 10 mbits up.
