I upgraded from Wheezy to Jessie today on my laptop. I cannot get wifi

tried removing everything network-manager related through apt and
starting over but that didn't work. I have network-manager and
plasma-widget-networkmanagement installed and can configure interfaces
through the GUI. Wired works, but wireless never fully connects no
matter if security (WPA2) is being used or not. See attached log.
I tried using Wicd and it worked fine to connect to wifi so I don't
think my hardware is at fault.
I am currently trying to figure out how to get more verbose logging
from
either network-manager or the wpa supplicant, all docs I can find seem
irrelevant so at least looking for tips on that.
Thanks,

An update.
added super debug mode '-dd' to wpa_supplicant startup in file
/lib/systemd/system/wpa_supplicant.service
Noticed the driver being used was 'nl80211'.
Copied /usr/share/doc/wpasupplicant/examples/wpa2-eap-ccmp.conf and
made an example conf file to run a standalone wpa supplicant instance
with:
wpa_supplicant -i wlan0 -dd -c wpa-psk-tkip.conf
Noticed that it just stayed in a loop of auth->disconnect->re-auth
(like it had been)
Forced the driver to 'wext', and it then worked fine....
Looks like this was a default that was changed during the Wheezy life
time:
http://w1.fi/cgit/hostap/plain/wpa_supplicant/ChangeLog
2014-02-04 - v2.1
* changed the default driver interface from wext to nl80211 if both are
included in the build
At this point I am trying to figure out how to get network-manager to
force and use the wext driver with wpa_supplicant. This page mentions
a config flag 'wifi-wext-only' but it doesn't work:
http://linux.die.net/man/5/networkmanager.conf
And forcing the wpa_supplicant to start up with -Dwext to force the
driver still allows network-manager to override and break again :(
This is on a Thinkpad T61, I have no idea how I am the only one bitten
by this....??
