    Question Wi-Fi stopped working after the first reboot (After clean install of 20.04 beta)

    Good morning,

    So after the clean install (of Ubuntu 20.04), everything worked perfect. I downloaded some files (like Transmission, chromium and some other apps), used internet, all was OK. But after the first reboot the Wi-Fi just doesn't work at all.

    The Wi-Fi card is an RTL8723AE . I have the same issues as: wifi networks lost after updating
    I have tried the following:
    sudo apt-get update && sudo apt-get install build-essential git dkms
    sudo apt-get install mokutil && mokutil --sb-state
    sudo apt-get install git build-essential linux-headers-$(uname -r)
    git clone https://github.com/lwfinger/rtlwifi_new.git
    cd rtlwifi_new
    make
    sudo make install
    rm -v -R --interactive=never rtlwif*
    Also some variants as:
    git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
    sudo dkms add ./rtlwifi_new
    sudo dkms install rtlwifi-new/0.6
    sudo modprobe -r rtl8723ae && sudo modprobe rtl8723ae
    echo "options rtl8723ae ant_sel=3" | sudo tee /etc/modprobe.d/rtl8723ae.conf
    But I have no good result.
    The point is: It was already working fine, why it all went wrong with a reboot? If it was working properly at first, what could be happening now?

    I also attach the text file generated by the Wireless Script submitted by the forum

    Thank you very much for your help.

    I encountered a problem similar to this on a different wireless device. Work around involved NOT rebooting, but Power Off, remain OFF for a couple of minutes, set Power to ON. My wifi device came back on; maybe yours will too.

    Well... Instead of trying to sign the drivers - you installed mokutil but there's no mention of using it so... - jus disable SEcure Boot in UEFI settings.

    No way to make it work again.

    @CelticWarrior

    jus disable SEcure Boot in UEFI settings.
    Just checked via BIOS. UEFI was already disabled.
    Even with command line for mokutil just says:
    EFI variables are not supported on this system

    Thank you

    I made another fresh install of Ubuntu 20.04 and the Wi-Fi is not working at all.
    I don't know what could happen, because in the first fresh install everything worked.

    It's official. Today I reinstalled the new version (official) 20.04.
    Wi-fi not working at all.
    Seems to be some kind of problem with the realtek drivers.

    I also put a question in askubuntu:
    https://askubuntu.com/questions/1229...stall-of-20-04

    And I am watching some similars (like: https://askubuntu.com/questions/1229...ading-to-20-04)

    I made it work!
    The big problem was, that thinking that the command dmesg | grep wlp4s0 was the point that fixed the problem I reinstalled Ubuntu 20.04 again.
    I can't make it work again. I have repeated the same steps but I just cannot. As I see in some other questions in askubuntu they had the similar issue and they don't know how they fix it (like I did):
    https://askubuntu.com/questions/1229...stall-of-20-04 (my question, thanks to @chili555 something solved the problem the first time)
    https://askubuntu.com/questions/1192...ifi-no-results (someone who solve it but didn't know how)
    https://askubuntu.com/questions/1155...after-updating (someone in the same situation as I am)

    FYI
    I made it work again. The only thing that happened was that the computer was off for a few days.
    Reinstalled Ubuntu 20.04 (same issue RTL8723ae not working again), trying to repeat everything so I find WTF is happening here.
