could someone help me fix the "unidentified network" problem?

#1
sorry for my bad English. I'm a Vietnamese so if there were any problem with my language, please ignore it. I've known a password of a wifi and have connected it for 4 months with no problem. But on a beautiful day, it turned out to be "unidentified network" and "limited access". I tried everything I search on Google but nothing seem can fix my problem. Here what I tried:
1. Go to services, try to find ##Id_String2.6844F930_1628_4223_B5CC_5BB94B87 9.762 but couldn't find it.
2. Configure the "wireless network connection" --> tab advanced --> set the value of Network Address with 12 any numberic digit but nothing happened.
Is there anything else I can do?
here's the "ipconfig/all" of my laptop:
