I am running Ubuntu-17.04 via a 16-GB bootable USB. Ubuntu is not installed on the usb or the disk.
HP ProDesk desktop computer, without Wifi. I am using a NetGear WNA 1100 (Atheros AR9271) USB dongle.

I am able to see all the Wifi SSIDs, but when I enter password, and try to connect, it does not. Presently I am using my phone via USB tethering. 

> sudo apt-get update   
> sudo apt-get upgrade   
> sudo service network-manager restart

Also, did not help me connect to wifi. I have also installed the ath9k_htc-installer_1-0-4.deb from https://sourceforge.net/projects/ath9k-htc/files/ath9k_htc-installer/ as recommend on https://help.ubuntu.com/community/HardwareSupportComponentsWirelessNetworkCardsNetgear#USB
