yesterday I format my laptop and install window 8.1. Now there is no wifi option in my laptop, not anywhere in the network option. I try to check if there is problem with my wifi by installing Ubuntu. It works well in Ubuntu bt not in window 8.1. plz help me fix my problem.
First of all, Windows 8.1 don't require any drivers the Os is meant for that, if you are not getting any of options regarding WIFI you can change them in control panel.
There may be a adopter problem by switching it on and off.you may get your WIFI options back.
You can have this settings in control panel-network connections.
Even then if you need wifi drivers,then you need to have your laptop series then you can download that particular series drivers from official website or other providers.
I managed to get mine working again by going into network settings going to VPN clicking change adaptor options and then three options came up. Bluetooth, Ethernet and wifi, wifi was disabled so I clicked it and it fixed itself again
