Wifi doesn't work in my new HP all in one f0045z with a Realtek PCI adapter. I cannot find anything about how to make it work or locate a driver.

$ lspci | grep Wire 02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter

$ nmcli general STATE CONNECTIVITY WIFI-HW WIFI WWAN-HW WWAN
connected full enabled enabled enabled enabled

$ rfkill list 0: hci0: Bluetooth Soft blocked: no Hard blocked: no

$ iwconfig lo no wireless extensions.

enp1s0 no wireless extensions.

thanks

I suspected a module signing issue, so I attempted to sign the module per the sys admin guide. While I was successful with most of the steps (creating and importing keys), I kept getting an error using the perl script to sign the module. I finally turned off secure boot and when I finished booting the wifi was working. Thanks for the help. For now I'll just leave secure boot turned off, I guess.
