How To Add New Connection in GUI Network Connections

I am a totally frustrated newbie. I have an Acer Netbook that had working WiFi under Windows 10. The WiFi is seen and it will list access points. But, it does not show in Network Connections. I deleted the blacklist file that had all Atheros Qualcomm Wireless blacklisted. Anyway, I tried to use Add New Connection in the GUI and couldn't get the "Save" button to activate. Is there a tutorial on what has to be entered to get the "Save" button to activate? I mean SSID, Password and automatic DHCP should be enough? How do I fix this?

Can you please post the terminal output pf lshw -c network to examine which wifi driver you need?

Have you enabled the module using modprobe?

sudo modprobe ath5k

I am not sure if enabling with modprobe as above was the trick or if I had been entering too many parameters in the add new connection. WiFi

But, it is working! And, I appreciate the response as quickly as it has happened.

Well, I thought it was working, apparently, I still have some information to add as it is still requesting a WiFi network adddress.
