    Question Ubu-20 keeps dropping my WiFi connection. Refuses to connect.

    I have Ubuntu 20.04 LTS installed and use a USB Wifi adapter for my Internet connection.

    When I start Ubu, my Internet connection ALWAYS starts disconnected. Clicking "Connect" tries for about 20 seconds then gives up.

    I have no idea what's wrong. The WiFi connection worked perfectly when I installed Ubu from a thumb drive, including downloading "third-party" drivers and software, but now that installation is complete, it is extremely difficult to establish/maintain a connection (which I'll always lose a few minutes later.)

    I'm typing this from Windows on the same PC using the same Wifi adapter. Any ideas?

    TIA

    Thanks for the reply.

    I downloaded the script from Windows to a thumb drive, copied it from the thumb drive to Ubu's Downloads folder, changed the Permissions to "Allow executing file as a program", and as noted at the link:

    [NOTE 1: Since Ubuntu 13.04, Text Files open up in text editor even if they are made executable. To change this-
    Open any folder > go to Files > Preferences > Behavior tab > select "Ask each time" option under "Executable Text Files" section.]


    But when I go to "Files" ("Downloads" folder open. Ubu 20.04), "Preferences" does not appear in the menu.

    I tried to change "Open With" to "Run Software", but that didn't work either. I might be able to execute it from the Terminal if I knew what command to use.

    TIA

    Update: I'm noticing I stay connected for about 15 minutes when I first boot into Ubu. Logging off & Restarting is the fastest way to reconnect.

    Very annoying.

    Lets try

    Code:
    sudo sed -i "s/wifi.powersave = 3/wifi.powersave = 2/g" /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
    sudo systemctl restart network-manager.service

    Re: Ubu-20 keeps dropping my WiFi connection. Refuses to connect.

    Hmm, I executed the commands from the terminal (Copy/Paste. Didn't retype) and it didn't appear to have any effect (I did reboot.)

    When Ubu starts, I typically (always?) have a connection, which can last anywhere from 30 seconds to 5 minutes.

    (my network is "Virus Central". Everything fine at first.)


    (Suddenly, connection stops, but visible networks still visible and icon stil says "Connected".)


    (A minute later, all visible networks disappear except mine, which is unable to connect... yet still says "Connected" on header [but icon on toolbar now shows broken].)


    As I mentioned, this is the same computer & same connection (same USB WiFi adapter) I'm using in Windows to reply.

    Big thanks.

    In a terminal what does the following command show for your card info?
    Code:
    lshw -C network
    post back here.
    also what is the output of
    Code:
    iwconfig

    those outputs look incomplete please rerun them with sudo (as super User)
    Or let us know which wireless card is in the machine.
    Also you can run the wireless script in my signature.

    Sorry for the delay:

    Running the commands with Sudo this morning actually produced less information. I'm not sure these will be helpful:

    Thx.
