After applying instructions from #18, my connection problems disappeared and has continued to work for about 6 weeks. Yesterday the "bad password" problem returned. I fixed it by changing to a different driver in Preferences ->Advanced tab from wext to nl80211. My system is running on a Dell laptop MT6821.
