Are you running kali, or any other linux distrobution inside of Virtualbox, VMWare?

If your running Linux in a virtual container you need an external wireless card. Also your on an HP notebook that was built to run windows 10, you would need to live boot from a USB or CD, and try configuring your network adapter with ifconfig then, also your wireless network adapter might have a different name other than wlan0(kali configures this by default, unless you are not running kali)

INFO: The network card ("wifi card") that's in your PC may not even support packet injection, or monitor mode.

Also make sure that if you put wlan0 into monitor mode:

sudo ifconfig wlan0 down

sudo iwconfig wlan0 mode monitor

sudo ifconfig wlan0 up

Verify that you put wlan0 up before you try running reaver

You may have not properly brought up your wireless network adapter wlan0 You should restart your computer, run the above commands to configure your network adapter, and rerun reaver. If that didn't work continue below:

INFO: If there is a hardware switch that controls your network adapter switch it on before executing the following command

The command is usually:

sudo ifconfig wlan0 up ; sudo rfkill unblock all ; sudo rfkill unblock wifi

If that is not successful, try restarting your PC (at bootup if you have a wireless switch on your PC switch it on now), and repeating the above command. You may also want to try: sudo ifconfig wlan0 ; sudo ifconfig wlan0 down ; sudo ifconfig wlan0 up

If it still is not working, the order of precedence with the above commands matters. If you didn't bring your network card wlan0 back up before running reaver, restart your PC and try again. You also might need to look into rfkill (radio frequency kill), and unblock your network adapter by sudo rfkill unblock all ; sudo rfkill unblock wifi (run command a few times, and restart PC)

If all else fails, don't give up the world of IT and Cyber security is amazing. Learn the basics, look up how to install ubuntu from usb, or if you want to skip learning and use tools, how to download kali linux on usb after that lookup hp boot from usb
