confiring wireless manually from the command line

Hi

I have been attempting to configure wireless manually from the command line on my Thinkpad 400, but have been unable to get a connection. I am using Trisquel 8.0 which I believe is based on Debian:

$ uname -a
Linux technoethical-t400s-b9d0 4.19.0-gnu #1 SMP Mon Oct 22 06:05:01 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux

cat /etc/os-release
NAME="Trisquel GNU/Linux"
VERSION="8.0, Flidas"
ID=trisquel
ID_LIKE=debian
PRETTY_NAME="Trisquel GNU/Linux Flidas (8.0)"
VERSION_ID="8.0"
HOME_URL="https://trisquel.info/"
SUPPORT_URL="https://trisquel.info/wiki"
BUG_REPORT_URL="https://trisquel.info/project/issues"

I am using the following commands to configure:

# disable NetworkManager
systemctl disable NetworkManager

#kill existing wpa_supp
ps -ef | grep wpa
pid=`ps -ef | grep wpa | grep -v grep | awk '{print $2}'`
kill -s SIGQUIT "${pid}"

#check interfaces and find wireles device name
$ iw dev | grep Interface
Interface wlp2s0

#check device is up
$ ip link show wlp2s0 | grep UP

#if not bring it up
$ ip link set wlp2s0 up

# backup config file
$ cp /etc/wpa_supplicant.conf /etc/wpa_supplicant.conf.bu

# check ssid can be scanned
$ iw wlp2s0 scan | grep lcwire
SSID: lcwire

# create wpa_supplicant.conf
wpa_passphrase lcwire [passphrase] > /etc/wpa_supplicant.conf

# check driver
$ lsmod | grep 9k
ath9k 151552 0
ath9k_common 36864 1 ath9k
ath9k_hw 479232 2 ath9k_common,ath9k
ath 32768 3 ath9k_common,ath9k,ath9k_hw
mac80211 798720 1 ath9k
cfg80211 659456 4 ath9k_common,ath9k,ath,mac80211

$ wpa_supplicant
....
drivers:
nl80211 = Linux nl80211/cfg80211
wext = Linux wireless extensions (generic)
wired = Wired Ethernet driver
none = no driver (RADIUS server/WPS ER)
....

# run wpa_supplicant
wpa_supplicant -B -D nl80211 -i wlp2s0 -c /etc/wpa_supplicant.conf -d

After doing this the syslog seem to indicate theat the conneciton is contiually being deauthenticated.

I have attached files with output from journalctl (syslog.txt) and the debug output from wpa_supplicant.

I have a machine with fedora on it where I do a similar set of commands (different driver - use-D ext) and it connects fine.

If I use NetworkManager (which came enabled when I got the system) it also connects fine, though for some reason I have to reboot after powerup for it to work.

Other Notes:
1./
ifconfig gives me the following:

Not sure where wlp2s0:avahi comes from - I do not see this on my fedora machine or when I use NetworkManager to bring it up, only the interface with the locally configured ipaddress received from the router.

hen the interface is working after rebooting with NetworkManager enabled ifcoinfi shows:

Has anyone any idea why I am seeing the deauthentication ?
Does anyone know what the wlp2s0:avahi interface is ? - It seems to have a random (external?) ip addess assigned.

Can anyone see/is able to guess what might be wrong with the configuration ?

Has anyone any idea why I am seeing the deauthentication ?

Does anyone know how I can get information from NetworkManager - config files, logs etc. to see if I can tell what it is doing differently ?

Does anyone know what the wlp2s0:avahi interface is and why it is generated ? - It seems to have a random (external?) ip addess assigned.
