I got my laptop (Vostro 15 5568) fixed by dell technician because of some broken screws. After that I turn on my laptop and found red cross sign at network sign. When I click Show Available Network, there is nothing. No WIFI signal at all. I can use only Ethernet to connect to the internet. Before that it works totally fine. I don't know what went wrong.
I'm at my wit's end. Any help would be appreciated. This problem also occurs with Bluetooth:
Thank you for your message. I apologize for the inconvenience caused. I will be glad to assist you with this.
What is the BIOS version installed?
Restart the computer & tap F2 to get into BIOS- Click on the Wireless tab – Click Wireless Device Enable – Enable WLAN & Bluetooth – Click Apply & restart.
