Hi Violentlee, Thank you for the information. I regret for the inconvenience. Here’s the correct link to update the chipset drivers: [URL] You may install the latest wireless drivers from the link: [URL] Hope this helps. Please feel free to reply for any further assistance.  
I've recently been given a new Inspiron 17 3721 with Windows 8 to add to our fleet of computers at work and need to downgrade to Windows 7. I can't seem to get any of the Dell drovers from the download section to  work. Many of them state upon trying to install the following - 'This self-extracting zip file is part of a multidisk zip file. Please insert the last disk of the set.' How do I get around this issue if in fact I'm even trying to use the correct driver(s). mt Service Code is <ADMIN NOTE: Service tag removed per privacy policy> if it helps get this right.  Violentlee
