Had to restore my XPS One 2710 from scratch using Windows 7.  System works well except I can't seem to activate a  wireless network.  Device manager is telling that both multimedia and network controllers are missing drivers yet I've installed all the available drivers for my system.  Ethernet controller works fine (Atheros AR8161).  Can someone please tell me what I'm missing?

Could it have something to do with a Windows update that simply will not install (KB4534310)?
