Not Able To Connect Internet To The Pi Project

Hello everyone, Thomas here. I’m having a weird problem with my Pi Project. I somehow managed to install Windows 10 IoT Core on it but now I am not able to connect it to the internet on my home network. All other appliances are working fine. I don’t know what is the main reason behind this. Earlier, I was able to solve this kind of problem with the help of this article. Now, this article is not helping me to solve this problem. Can anyone suggest to me some solution? Any kind of feedback would be highly appreciated.
