thanks for your replies, I was actually remembering the thing Textar said, so I didn't read the post (recently, I had read it, but forgot it, in the past).
I wrote down what u suggested me and was ready to try it out, i tried it and I got some output which I was ready to post here.
Still I wanted to be sure it was not a problem in my settings and be 100% sure it was an update problem.
I tried my backup (mylivecd) and runned live,...it worked, so I checked the settings and wrote some down.
I rebooted, and I was that one field was missing WPA-EAP IEEE8021X NONE was missing in the advanced section.
Now all works perfectly, so it was not an update problem, but a problem in the settings, thanks anyway.
Only strange thing is who did change that setting?
Marked as solved
