Wi-Fi not showing and only ethernet works.

[Udoy047]

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. But I forgot to check the wifi options. When I returned back home and tried to connect to my wifi connections it only shows the airplane mode. No wifi and other options are showing which I used to get earlier. Also, I can't turn on or off the airplane mode on screen. Only the button (F12) works for this. I can only access internet through ethernet. Only the ethernet cable is working. I have tried several googled solutions and watched many YouTube videos but can't fix my issues. In my network adapters many drivers are missing like wifi, Bluetooth, etc. I have attached several screenshots which may help you guys understand my problem.

Why is this happening? Did my technician make any mistakes while repairing the motherboard? How can I resolve this issue?

It is 10 years old now but it should have wifi adapter. What is it ? Could be due to missing driver

Regards.

I also suspect that. Would you please tell me how can I get back or install those required drivers?
