Hello wasimbhatti, Thanks for the detailed post. Looks like you’re missing a Chipset driver and the Dell Wireless driver. Unfortunately when chipset drivers are not installed first it can cause issues with other driver installation after so it’s always recommended to clear any chipset installations initially after a new install. Hopefully we just need to get that driver installed though. Here is a link to the systems Chipset drivers. Intel Lynx Point Chipset [URL] Intel Management Engine [URL] If these fail to install I would recommend attempting to manually install from the device manager or using the Intel Auto update tool: [URL]   After installing the missing chipset driver, the Dell Wireless card should install from the following link. Dell Wireless 1705 1x1 WLAN 802.11b/g/n (2.4GHz), Bluetooth v4.0+HS  [URL]   Thanks,
