I am on Debian testing with 2.3.1+deb8u4 being the last working version in conjunction with network manager.
So wpasupplicant 2.5-2+v2.4-3b1 is broken for me without the option "wifi.scan-rand-mac-address=no" in the networkmanager.conf The network-manager retries to connect all the time but with no success. I am using this USB Stick to connection to my wireless: AVM GmbH FRITZ WLAN N v2 [RT5572/rt2870.bin] Attached you can find the dmesg output with wpasupplicant 2.5-2+v2.4-3b1 after doing a "service network-manager restart"
wpasup-dmesg
