    Ralink RT5390 wifi not properly working on Ubuntu 20.04

    I'm totally new to ubuntu, it's been 2 days since i have been using this, everything seems fine but have been facing issues with my wifi connections.
    Wifi signals always are weak even at very small distance from wifi hotspot. When i bring hotspot close enough I get good signals but still the network speed is really slow, many times it would disconnect by itself, then I have to turn wifi off and on to re-establish the connection.

    Need help with it, think this is the right place to get it solved.

    sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

    Found this but it didn't worked

    I could provide whatever the logs needed

    used below command, maybe it could be of some help
