The wifi option is not showing. I checked the device manager for my wireless network adapter. But the network adapter is missing. Now I'm accessing the internet via ethernet. Can anyone help me? 

Previous logs:

No windows updates have been done before this problem. But I have given my laptop for repair (my power button was damaged). Just after the repair, the wifi option goes missing.
