So i sat up a hotspot, with udoo-softap and hostapd it works fine, but i cant figure out how to reverse it, so that Udoo Neo can connect to other wifi again. The documentation says if I remove Udoo-softap the wpa-supplicant will work again. when I do so it doesn't work.
Could you paste your /var/log/syslog and /var/log/kern.log? Did you change your /etc/network/interfaces?
