I still haven't solved this problem.
The timing has changed. So at first I thought it was a router/dhcp problem (lease on 30 mins). But I always used those settings. Coíncidently I was also changing options on my wifi. I changed them back (channel, auto, stuff like that), but it did not change anything (nor should it).
The first certificate warning takes a while to appear. Then they slowly become more and more frequent until upto a point where I MUST connect to unprotected wifi.
Chrome on windows learned me that virii can cause strange behaviour like this.
I also have a lot of problems with the unlock screen. Often it will just not react anymore. Only a black display (and maybe a blinking led). Also my AutomateIt voices were often stuttering like the phone was under very high CPU/RAM load. I did not have these problems from the beginning but combined with the fact that the phone sometimes just reboots or needs a battery eject... Starts to sound a lot like the infamous Samsung 4.3 roll-out:

http://www.gottabemobile.com/2013/11/12/samsung-galaxy-s3-android-4-3-update-problems-emerge/And yes, at times I also experience an EXCESSIVE battery drain. Usually I notice tthe emptied battery problem being followed by a non-responding lock screen (or reboot; or virtually non-responding).
And lastly, pressing home when (just) being locked could also be a cause instead of a symptom... :S
So things to do:
1. router reset (did not do that yet - only android has problems and my mini-mining-rigg cannot be disconnected. Maybe in 10 years or so ; -)
2. check for virii. I am currently installing al major (and unmajor) antivirus programs. I got some warnings, one or two that I could not easily explain. Of course I just removed anything I wasn't sure of. Still, the unlock problem remains - and I even unplugged the battery once more
3. new firmware. Starting the beginning of December (on Real Santa Claus Day to be exact;) Samsung has started rolling out new firmwares again (after being discontinued for a month).
BEFORE I do the new firmware, I FIRST will test by restore current system ROM. I expect it not to wipe my apps and icons (but that's a gamble I still do not fully understand;p).
So not over, not by a long shot
No karma

PS: also hinting on virus infection is the fact that I was checking and installing the November 2013 torrents for rebuilding my phone.
PS: I shortly also suspected my ADB tools (wifi && lock protector). But I used those programs almost from the beginning...
PS: Avast was installed al the way through; including Lost & Found
I removed that too, but it did not change much. Also, on PC downloading torrents, Avast was active. And Zemana AntiLogger.
