Windows 7 could someone help me fix the "unidentified network" problem?

[genius3008]

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:

It seems like you're experiencing connectivity issues with your Wi-Fi network, resulting in an "unidentified network" and "limited access" error. Let's address the steps you've already taken:

• Searching for the ##Id_String2.6844F930_1628_4223_B5CC_5BB94B879.762 Service: This service you mentioned seems to be related to a specific network configuration but may not be directly related to your current Wi-Fi issue.
• Configuring the "Wireless Network Connection" Settings: Changing the Network Address (MAC address) to 12 numerical digits is not a common solution for fixing Wi-Fi connectivity problems. It's not recommended to modify this setting without a specific reason. Given the information you provided, here are some troubleshooting steps you can try to resolve the "unidentified network" and "limited access" issue:
• Reboot Your Router: Sometimes, issues with the router can cause connectivity problems. Try restarting your router by unplugging it, waiting for a few minutes, and then plugging it back in.
• Forget and Reconnect to the Wi-Fi Network:
• Go to your Wi-Fi settings on your laptop.
• Forget the Wi-Fi network you're having trouble with.
• Reconnect to the network by entering the password again.
• Update Wi-Fi Adapter Drivers:
• Visit the website of your laptop manufacturer or the Wi-Fi adapter manufacturer to download and install the latest drivers for your Wi-Fi adapter.
• Check for Windows Updates:
• Ensure that your Windows OS is up to date by checking for and installing any pending updates.
• Disable IPv6:
• Sometimes, issues with IPv6 can cause network problems. Try disabling IPv6 on your Wi-Fi adapter.
• Go to your network adapter settings, locate the properties of your Wi-Fi adapter, and uncheck the box for IPv6.
• Run Network Troubleshooter:
• Use the built-in network troubleshooter in Windows to diagnose and fix common network issues.
• Go to Settings > Network & Internet > Status > Network troubleshooter.
• Check Firewall and Antivirus Settings:
• Temporarily disable your firewall and antivirus software to see if they are blocking the network connection. Please try these steps and see if they help in resolving the Wi-Fi connectivity issue. If the problem persists, let me know so we can explore further solutions.
