Activating Macbook

Hello
So I reset my macbook awhile ago and successfully completed the process.
However, when I about to activate it, it says that I have to choose a wi-fi at the menu or attach a cable network to continue.
Upon checking, there's ain't any wi-fi at the menu, I tried to look at the google of what could possibly I should do to fixed it but one of the article says that I have to remove the mac at the assistant recovery for the wi-fi connection to showed up so I did it but it never works.
I hope you could help me fixing this mac issue
Thank you and have a great day ahead.
