    I know this problem seems really similar to the one posted by this thread, I tried the following solution provided by them but nothing changed

    Code:
    sudo add-apt-repository ppa:lexical/hwe-wireless
    sudo apt-get update
    sudo apt-get install rtl8192ce-dkm
    I tried downloading drivers from the internet and attempting to install them but I always got "hardware not detected". I installed ndiswrapper and then tried to use the .inf file to install the driver. Did not work. What I tried is summarized in this thread

    Code:

    I even tried installing the bw43fcutter and all that using the following thread

    I am so tired and frustated please help me

    and does toggling the Fn-F8 wireless on/off command do anything? I wonder if it has fallen asleep.

    Well, I tried that , that does change the LED that indicates if the wireless is on or not. but does not help in detection of wifi hardware. So even when the Wireless LED is glowing, no wifi hardware is detected
