'No WIFI networks found' My laptop is not detecting WIFI

Recently the LED of my laptop was changed.After repair my laptop came back and Then I turned it on but it could not connect to any Wifi because it is not detecting any Wifi. Before repair there wasn't any issue with network connectivity. But my phone is connected to the wifi available. The laptop is only connecting to the Mobile hotspot only when the phone is near the laptop otherwise it does not connect. I have tried to reinstall the wifi drivers but it still does not detect any wifi.

Hi,

By LED do you mean the LCD screen?

It may be that the WiFi antennas have not been plugged back into the WLAN card when the screen was replaced or they have come loose from the WLAN card.

Here’s a link to the service manual for your laptop.

Scroll to p.40 to view the necessary pre-requisite steps and then the procedure to remove the WLAN card. You don’t have to remove the card, just check the antenna connections
