My laptop came with Windows 8 preinstalled in it. The WIFI was working fine then. After that I upgraded to Windows 8.1 and then to Windows 10. There were no issues with the WIFI connectivity. After some days my laptop started to hang and then ultimately it crashed. I deleted Windows 10 and installed Windows 8.1. But during the installation, I was unable to connect to my home WIFI. I skipped that step but after installation also I was unable to connect to my home WIFI. In both the cases, it is showing that the connection is limited. But when i install Windows 10, I am able to connect to the WIFI during the installation process and also use it after installation.

I do not want to install Windows 10 since my laptop crashes in a few days everytime I do it. I want to install Windows 8.1 but I am facing this connectivity issue. Please help.

    The support page for your device should have Windows 8.1 compatible drivers for the device. You should download and install those. – Ramhound Aug 15 '18 at 20:15
  • Exactly as in the previous comment. Windows 10 has native support for your WiFi and that's why it works OOTB, older versions don't so you need to either reinstall (the OS) with manufacturer's media or recovery system or download the drivers from another PC and transfer them to the laptop with a thumbdrive and install. Or try connecting with an alternative method (Ethernet, phone tethering, etc.). In some cases Windows Update downloads and installs some missing drivers in the background. – GabrielaGarcia Aug 15 '18 at 20:27
  • @Ramhound, I did. No use. – MrAP Aug 16 '18 at 7:40
  • @Except my home router and my phone, all other sources of WIFI work. – MrAP Aug 16 '18 at 7:42
