Network card issue on Ubuntu Linux

Hello,
I have an Acer computer running Linux Ubuntu, and it does not detect my network card. Therefore, I have to use a small USB network adapter to connect to the internet.
However, it does not allow for a great connection speed and occupies a USB port,
so I would like to be able to use the network card.

I used the command lspci | grep -i 'network\|wireless' which allowed me to find out that my network card is a Qualcomm Atheros Device 004.

I would like to know if there is a possibility to enable my computer to detect this card and to use it.
Thank you in advance for your responses.

Configuration: Linux / Firefox 45.0

    Hello,
    There are plenty of Atheros cards, give us the exact model.
    Open the terminal and provide the full result of the command 
    lspci | grep Wireless
    .
    -1

      Thank you very much for your response, but at my place the command lspci | grep Wireless returns nothing.
      So I tried other commands, like lspci | grep -i network
      , but it returns no more information (only 03:00.0 Network controller: Qualcomm Atheros Device 0042 (rev 30))

      and also with sudo lshw -C network
      which gives
      • -network

      finally with lspci | grep -i net
      which gives

      I haven't been able to get more information.

      Nevertheless, I thank you for your response and hope that you can help me.

      Apparently, it's a card that is resistant:

      However, it seems that someone has found a solution to get it working
      See post 23 on this page:

      I had already tried this method without success.
      I will try again or wait for the release of a driver or method that works.
      In any case, thank you very much for your help.
