HP ProBook G1 450 Networking :: WiFi Won't Turn On - Driver May Be Missing Or Corrupt

The Wifi on my a new ProBook won't turn on. Device Manager says that the device driver for Wifi won't load and may be missing or corrupted. It says the wireless device is an Intel Dual Band Wireless-AC3160 with Bluetooth combo device. The HP driver support page doesn't have a driver for this wireless device.

This is a new ProBook G1 450 which I am still doing basic setup on; I haven't even added my programs to it. I am setting up the preinstalled OS with the HP preinstalled programs. It does successfully connect to the internet via an ethernet cable, and I downloaded many Win 7 and HP updates that way. But it will not connect via a wireless network. It does not recognize that there are any Wifi signals in the area. My old Thinkpad and my tablet recognize a number of strong Wifs in the area, and connect easily to the one which I am authorized to use. The ProBook says there is no wireless in the area.

The ProBook's Wifi is apparently disabled. The wireless light is on (white), and when I click the appropriate icon, there is a message saying that Bluetooth is enabled, but Wifi is disabled.  The light is supposed to turn on if either of Wifi or Bluetooth or both are turned on, so it is not a malfunction if it turns on when only one is enabled. But I have not tried Bluetooth yet.

Many other ProBook G1 450's apparently have a Ralink wireless device or certain other devices. Not mine. My ProBook apparently has an Intel Dual Bank Wireless-AC3160 with Bluetooth combo device. That's what Device Manager says. And this device might be excellent or perhaps even a nice improvement. However, unfortunately, Device Manager also says "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)."

The HP support page for driver downloads for my ProBook does not have any driver for such an Intel wireless device. I didn't try the wireless until having installed many Win and HP updates. At the same time that I have noticed the wifi problem, I found that one HP update won't install: that was for Hotkey Support 5. Since then, I am having a little trouble with a couple of other updates. I mention this in case it is of some interest, but I don't see any connection between these updates and Wifi.
