    wifi crashes after some usage

    I have "Intel Corporation Wireless 3165" wifi card. After some time my wifi connection drops, system can not find any wifi signals. Rebooting ubuntu fixes issue. But after it drops again. I was using linux mint without any issues. Can anyone help? Thanks.

    Code:
    arda@pc:~$ iwconfig
    lo        no wireless extensions.
    
    enp3s0    no wireless extensions.

    Moved to Networking
    In terminal
    Code:
    sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
    sudo iwconfig wlp2s0 power off
    Reboot
