Hi all, i recently acquired an alfa AWUS036NH but i'm having some issues.
I'm using kali 2.0 and now i have a PCI wireless card and a USB wireless card (alfa AWUS036NH). When i try to use the second one i need to use airmon-ng check kill or it don't go in monitor mode and when i do it it says that kill the process wpa_supplicant. At this point i'm able to use my card but after 2-3 minutes it stop to work, and stop to work also the PCI one that i try to use with the my wifi, it stay connected but don't load any pages. This until i reboot the system.

Also, i don't know if this can be the issue, when i start the system i have this error:
failed to start open vulnerability assessment system scanner daemon in kali 2.0
i tried the commands:
openvas-stop
openvas-start
as i saw in a post here and i get this error:
Starting OpenVas Services
Job for openvas-scanner.service failed. See 'systemctl status openvas-scanner.service' and 'journalctl -xn' for details.
Job for openvas-manager.service failed. See 'systemctl status openvas-manager.service' and 'journalctl -xn' for details.

Any idea how to get the wireless cards work?
