having the iw option power_save turned on appears to have been the cause of my suddenly useless my wifi connection
though i don't remember turning this option on intentionally i can't rule that out - or maybe is set in 12.3 scripts?
i use the physical 'on' switch for the wireless card and have not modified the power settings on wifi cards in previous versions of OpenSuSE, even when we had to build the wifi modules manually... power_save=on would not mean don't bother to power the card, if i were guessing
from this in the log:

chased down reason=3 and found it was related to power - the physical switch turns card off/on - and cycling that power is recognized by NetworkManager - tries to bring up the card, gets a dhcp address briefly - then fails
iwconfig wlan0 power off
iwconfig wlan0 power on made no difference
however
iw wlan0 set power_save off
suddenly brought the card back online - turning it back on does not appear to kill the link
two other changes at roughly the same time could have impacted the issue:
1. commented out the regulatory domain entirely in
/etc/sysconfig/network/config
#WIRELESS_REGULATORY_DOMAIN=''"
2. killed the dhcpcp-hook that was stuck attempting to get an address assigned
not sure if those could have affected the result. now to reboot and see if the issue remains fixed.
now to reboot and make sure that was the real fix.
had none of that trouble with 12.2 - wanted to provide this admittedly imprecise report - in case the same is helpful to others.
