NOPE. NOPE. and NOPE. Neither of these worked. Seriously, how hard can this be? I sent you the hardware IDs. Let me say it once again: Inspiron 3721 and Windows 8 64 bit. Are you telling me I have a 'special' Dell Inspiron that can never use Windows 8 AND wireless?
Do I need to crack the case and look for identifying marks on the chips? This should be basic stuff. Wireless LAN driver for Inspiron 3721 with Windows 8 64 bit. Is there any way I can further clarify this? I've been through every driver that can be downloaded for this machine (and the last ones you suggested that are for neither this machine or Windows 8).
