Dear Experts, I recently installed windows 8.1 on my Dell Inspiron 14(3421) but now I can't see any wifi networks on my network list. Simply, there is no wifi now. But, I can connect to the internet via Ethernet cable.Previously I was using 32-bit Win 8 and everything was fine. I checked the device manager and found that under óther devices', 'Nework Controller' and ÚSB 2.0-CRW' have yellow exclamation mark and have no driver installed. I tried installing driver for network controller but none of them were relevant. I tried updating driver from the properties of Network Controller but windows could not find any. Please please please help me by suggesting what should I do? or what is the relevant driver for my Network Controller?
