If you're able to get the wpa_supplicant logs, that would be useful as
well.

sudo dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugTimestamp variant:boolean:true

sudo dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1
/fi/w1/wpa_supplicant1 org.freedesktop.DBus.Properties.Set
string:fi.w1.wpa_supplicant1 string:DebugLevel variant:string:"msgdump"

will start spewing out tons of information to wherever the supplicant
sends log information on Ubuntu (systemd, syslog, etc).
