I have tried 0.5 before but never managed to get it to connect to my Asus router, which has a hidden SSID.
The difference between 0.4, which works, and 0.5, seems to be some lines missing from /etc/wpa_supplicant/wpa_supplicant.conf
I added:
eapol_version=1
ap_scan=1
fast_reauth=1
- and 0.5 connected immediately.
