    Re: 12:04 LTS, Toshiba Satellite L850, RTL8111/RTL8168 WiFi non existent. HELP

    tristan@tristan-Satellite-L850:~$ sudo modprobe rtl8192ce
    tristan@tristan-Satellite-L850:~$
    When the terminal comes back blank, that means, roughly, 'command executed as requested and I have no errors or warnings to report.' That's exactly what we want!
    what is the "key" to press to bring the terminal without having to the "dash" to fetch it?
    Ctrl+alt+t.

    Let's poke around a bit. Please post:
    Code:
    iwconfig
    dmesg | grep rtl
    rfkill list all
    The pipe symbol | is on the right side of my US keyboard on the same key with \. Thanks.

    Ah, ha! Finally we see it! With the ethernet cable attached, please do:
    Code:
    sudo apt-get install linux-firmware
    sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce
    Are we there yet??

    Yeahhhhh, we have progress. I can now see the "enable wireless" in the top right corner. Can't see the router though

    Of course you may (Boy, you are so patient!) Thank you so, so much.

    What..?? I thought it had firmware??? Is it not grabbing it when it actually exists?
    Code:
    ls /lib/firmware/rtlwifi | grep B.bin
    If linux-firmware didn't install it, we can get and install it for you.

    Ahahahahah, if you say so... whatever "firmware" is.

    tristan@tristan-Satellite-L850:~$ ls /lib/firmware/rtlwifi | grep B.bin
    tristan@tristan-Satellite-L850:~$

    Still can't see any wireless option.

    That means the firmware is not present. Please download the file I've attached and drag and drop it to your desktop. Right-click it and select Extract Here. Now back to the terminal:
    Code:
    cd Desktop
    sudo cp rtlwifi/* /lib/firmware/rtlwifi/
    If you get any warnings that a file already exists and do you want to over-write it, say Yes. Now unload and reload the driver:
    Code:
    sudo modprobe -r rtl8192ce && sudo modprobe rtl8192ce
    Now are we there?

    EDIT: Off for the evening. See you tomorrow.
