You are not alone http://en.community.dell.com/support-forums/network-internet-wireless/f/3324/t/19347574.aspx  This one that I linked was a possible Bios issue.  It uses the Broadcom chipset, so it should be rock solid and not having this issue.  It is either going to be the bios or it is going to be a child process that is causing this.  Both are hard to diagnose.


If Dell does not blacklist cards in the bios for that unit, you could try replacing it with the Intel 7260 Dual-band Wireless-ac mini-PCIe Card.
