[Galaxy Tab S2 Android Development] CTXz:
Ok so to wifi :

I know most of you want as number 1. priority a working WIFI connection, but this doesn't seem to be that easy to fix, at least not for my empty brain. As you've probably already noticed, my debugging skills are still quite bad (Yes I'm still learning... Yes I'm not perfect.... well maybe yes... ok no just kidding). The current issue i'm facing has probably to do something with the api drivers and wpa_supplicant. I've noticed that the KMSG doesn't even show a tiny trace of the cfg80211 driver and the nl80211 driver. If any developer out there knows what to do with the following log output when trying to access the wifi HAL / Enabling WIFI please tell me.
