I have a Dell Inspiron 3521 that had Windows 10 installed. It is a 64-bit system. I have a piece of software that I use every day. It will only operate on 32-bit. I have a legal copy of Windows 7 Home Premium 32-bit. I have just installed it, but wireless networking won't work. When I look at Device Manager, the only network adapters installed are 2 Bluetooth devices. When I look at Other devices, it tells me that Network Controller, PCI Simple Communications Controller, SM Bus controller, Universal Serial Bus Controller and USB2.0 CRW do not have installed drivers. I've gone to Dell's website and can't locate 32-bit drivers for any of these items. Anyone have an idea how I can solve this mess?
