The problem is solved. It was Bob Weber post that led me to solution, though the problem was a kind of different. Here what I mean. Just by looking at my password, as entered into NM, I did not find any weird characters or trailing spaces in it. A typo was exclued since I copy-pasted it from my password manager storage. I was in loss and just for no reason, when in GNOME "Authentication required" dialog pressed Backspace once... All at a sudden I get through and connected!.. Then I copied the password I uncessfully tried to use in Network Manager and pasted it bellow a password copied from my modem/router (or as David rightfully called it "gateway" device). That was it. The original password was 64 characters and the one in my modem was only 63 characters. Aparantly the modem has a limitation on the password length, which it neither shows to a user. Instead it sighlently cuts off any excessive characters. Silly programmed device wasted 2 days of my time. Anyway I'm a happy bunny now, since it solved. :-) Thanks folks. And the bigest credit goes to Bob.
