Problem with hotspot - WiFi connection on, but internet is down



  • I often connect my laptop (U20.04) via Android hotspot (Redmi Note 10 5G).

    Systematically, after a while, internet connection on my laptop disappears. In particular, the indicator shows that there is still a wifi connection with my phone, but internet is not available.

    Two solutions:

    1. Turn off and turn on wifi on my laptop- After this, internet connection comes back
    2. Turn off and turn on the hotspot on my phone. After this, internet connection comes back

    Anyway, in both case, after a while the internet connection disappears again.

    I've tried my laptop with other networks (also with other hotspot), but the problem is not present.

    Is there some way for fixing this? Is these some way for performing a diagnostic test?

    Please ask if additional information are required.

    Thanks in advance!



  • I have a fix for LinuxMint which is derrived from Ubuntu and I posted the fix on LM.

    Using "Search" (application), I searched for ".conf" in "File System" and found the file /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

    This .conf file contains:

    [connection]

    wifi.powersave = 3

    (and I changed it to 0 (zero), but you should set it to 2)

    After I posted the above, someone added the below on-line.

    Changing it to 2 is disable, 3 is enable, 0 is default value, 1 is don't touch existing setting.
