    WiFi adapter not detected after low battery suspension Fedora 29

    [RESOLVED]

    I have a Galago Pro running Fedora 29. The computer went into suspension because of low battery. Now, Fedora does not detect the wireless adapter -- meaning the gui manager returns "No WiFi adapter found...".
    The adapter was working correctly prior to the suspension.

    `rfkill list` shows no hard or soft block.
    `lspci` shows:

    `ip link set wlp3s0 up` has no effect

    I have tried a hard (cold) reboot, restarting networking, and restarting network manager.


    Here is my system info

    Neither of those packages are installed, so no settings

    Can you add a new user to your system, cold boot it again, and log in as that different user ? and tell me if the WiFi device is found ?

    Thanks for getting back to me. I am sorry I did not post that I solved the problem.

    It looks like my most recent update failed on parts. I did another DNF update / upgrade and the problem went away. The reason I tried this route is I found that network manager was missing some components.
