    After I get this fixed, I want to look into those classes for Linux. Thanks for your help

    Yes, that does not really surprise me, given what we are unravelling :)

    Thanks for those pix, the one I was keen to see was the Advanced Options one that features Linux kernel 4.15.0-20 only. You haven't answered yet about the updates.

    Do you have Ethernet at home, to run the updates, or have you done so?

    Linux kernel 4.15.0-20 is apparently the one 'Tessa' ships with, I put on the MATE edition last night and found similarly.

    There is a newer version available, as you can see here.

    It is possible that if you update to the newer kernel, the wifi will work.

    I have to go out for a couple of hours but I'll be back with more.

    Cheers

    Always welcome, it's what we do here :D

    I can recommend at least one.

    I thought I did but I will verify. Some of them didn't update.

    Damn' shame, that :(

    On your Ethernet, try this:

    Code:
    wget https://github.com/lwfinger/rtlwifi_new/blob/master/firmware/rtlwifi/rtl8723befw.bin
    If that is successful, then

    Code:
    sudo cp rtl8723befw.bin /lib/firmware/
    Reboot.

    Report back.

    Cheers

    Chris

    I connected to my WiFi and then I turned it off. I have been out of town for a bit. My next couple of questions, what now. You think it's good now? Also is there a way I can have it boot up before window or going into the boot menu and booting from my USB?

    Hang on a sec, let's back it up a little bit.

    Are you saying that that command line exercise worked, and that the wifi is working now?

    I'm going to verify tomorrow but I unplugged the Ethernet after I did the reboot. It took only a moment and it connected to my network

    If it sustains a couple of warm boots and a couple of cold boots, you should be good to go on with.

    If the wifi is good and you'll bear with me a little longer, I'd like to lock into place a snapshot of your system, so that if anything goes wrong in future, you can roll back to a working environment.

    You have a utility in place already, on your Linux Mint 19.1 that can do that, and that is Timeshift. You may have already seen a reference to it if you ran your updates from Update Manager, which looks like this when up-to-date.

    [​IMG]


    It might have had a "nag" message about setting up scheduled snapshots.

    If you haven't come across it, you can read about it at my Tutorial HERE, or else Linux Distro Linux Lite have a good little guide HERE.

    Cheers

    Just ried to boot up this morning and everything was good but I couldn't connect to my network. I honestly thought you fixed it.

    Yeah, I guess it was too early to break out the champagne :(. We are making ground, though, and I thank you for your patience.

    I'll send out a ping to @JasKinasis and @Lazydog and any others whom know more about wifi than I (which is many) and hope they have some good value.

    Chris, in your menu is Synaptic Package Manager, we may be making use of that to see if some packages are installed or not.

    Meantime, can you give me the output of

    Code:
    apt-cache policy network-manager
    ?

    Mine looks like this

    Code:
    [email protected]:~$ apt-cache policy network-manager
    network-manager:
      Installed: 1.10.6-2ubuntu1.1
      Candidate: 1.10.6-2ubuntu1.1
      Version table:
     *** 1.10.6-2ubuntu1.1 500
            500 http://mirror.as24220.net/pub/ubuntu bionic-updates/main amd64 Packages
            500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages
            100 /var/lib/dpkg/status
         1.10.6-2ubuntu1 500
            500 http://mirror.as24220.net/pub/ubuntu bionic/main amd64 Packages
    The 500 means it is installable, the 100 means it is installed.

    Thanks for that, now might be a good time to make the acquaintance of

    Code:
    nano
    Nano is a command-line Text Editor a number of us use (there are others). Have a read through this Post before trying this.

    At Terminal, you will be issuing the following command (when I place a # it is me making a comment, not a command to type)

    Code:
    sudo nano /etc/NetworkManager/NetworkManager.conf
    
    #note the capital N and M
    You may get something like this


    [​IMG]

    Navigation is by your direction keys, up down, left,right

    Change "false" to "true" like so


    [​IMG]


    Saving and exiting is performed as follows - the little "carets" (^) at bottom represent the Ctrl key. So ^X (small x will do) leads to


    [​IMG]


    ... and then it is capital Y to save, which leads to


    [​IMG]


    At this point, if you wished to employ a "Save As" action on a file, you could change the name, but we won't, and so it is just Enter and will leave the nano shell and be back in Terminal.


    Finally, unplug your Ethernet and enter the following

    Code:
    sudo /etc/init.d/network-manager restart
    
    #note lowercase letters and the dash (hyphen)
    See how you go

    It didn't work. Should I start over from scratch?

    Are you familiar with Murphy's Law? Basically, it says, what can go wrong, will go wrong :)

    From all the research I have done over the last week, it seems that the rtl8723be card/driver is one of the most "problematic" with LInux. And a User such as yourself cannot be expected to know that when they try to take up Linux.

    I can see one further option at the moment, and that is -

    at #35 above you had the pic of the kernels screen from Update Manager, at the top is kernel 4.18.0 -13, this is a short-term kernel supported until August 2019.

    If you click the line it is on, you will get a choice to install.

    Install it, reboot and report back.

    If that doesn't work, you may have to try another Distro (using Live USB sticks to see that wifi is working), or consider replacing the wifi card - I know, a PITA:(

    Cheers

    Got it working on it now. Worse case would a WiFi adapter work?
