I found the driver by going to the business PC support website, and looked up a business notebook that has similar hardware as yours, and then looked up the latest Intel wlan driver. Since I don't work for, or represent HP, I can't answer your first question. Now you can run the Intel driver update utility as the other forum member suggested and see if it gives you an updated driver. Unfortunately I would have no idea what version would be installed for each model wlan card supported by the driver package. If Intel supported the 3160 for the latest driver, then it would have installed the latest driver (19.30.0.4). The driver would have installed version 18.33.51 for your card, and not 19.30.0.4. And I posted the driver I posted last night. Where can I find the latest driver for this card?. Let's say you didn't have a wireless driver installed at all for your AC 3160, and posted a question.I need a driver for this card, and I want the latest one. While the latest version is 19.30.0.4, apparently Intel is only supporting your model wlan card up to 18.33.51, so the installer doesn't install the latest version available, because your model is not supported for the latest version. Inside the driver file are the drivers for various model wireless cards, including the one your notebook has.
