    Qualcomm Atheros AR938x Wireless Network Adapter Not Found

    Ubuntu 18.04 cannot find my Qualcomm Atheros AR938x Adaptor. It is switched on and working properly and I get "No WiFi Adaptor Found" when I select Wi-Fi. I have tried several commands in the terminal to try and find it to no avail.

    Any help would be most appreciated.

    Can you copy and paste here the output of lspci -nnvv ? You can use http://pastebin.com for this.
