Hi, good day! I'm John Dev a Windows user like you and I'll be happy to assist you today. I know this has been difficult for you, Rest assured, I'm going to do my best to help you.
I will ask a few questions, so I have a better idea of what solutions to provide.
When was the last time it worked properly? Have you tried installing the latest Wireless driver from the manufacturer's support page? What is your current Windows operating system and version? Press Windows key+R to open Run then type: winver
Kind regards,
