Windows 10: Wi-Fi not showing and only ethernet works

Hello Everyone, Hope you are all doing well. I have an HP Pavilion which I bought back in 2014.I forgot the model name. The day before yesterday I was unable to turn on my laptop. I took it to the technician, and he told me that my mother board is faulty and requires service for the last one year I had to fix many things since my laptop became old. Originally, I had a 4 gb RAM. Since working slow, I told him to install a 8 gb RAM also. I told him to fix the issues. He fixed the issues and I checked everything and my laptop worked well.

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?
