    sudo ifconfig wlo1 up
    SIOCSIFFLAGS: Input/output error

    i have also restart the network manager but still there isn't any improvement

    i can enable/disable networking and wifi but under wifi networks it shows devices not ready
    same kind of problems were there when i was working on windows

    Hiya, post the output of

    $ uname -a
    $ lsmod

    and install & run the wireless info script from
    https://ubuntuforums.org/showthread.php?t=370108

    and paste the result here using a [CODE] tag .. thanks , lets hope it's a driver issue/conflict and not a hardware failure!

    # hopefully a staff sees this thread and moves it to it's proper section Networking & Wireless , so that it receives more attentions.

    Re: Wireless connection failure

    Oh, by the way

    sudo ifconfig wlo1 up
    SIOCSIFFLAGS: Input/output error
    Might not work as well as

    Code:
    sudo ifconfig wlo1 down
    sudo ifconfig wlo1 up
    For some reason, switching the wireless adapter off/down before switching it on/up seems to work better then simply commanding it to up. And you do have a driver installed

    broadcast=yes driver=rt2800pci driverversion=4.10.0-27-generic firmware=0.37
    Does clicking the Network Manager icon produce a drop down menu with a list wireless access points in range? Is your wireless access point included?

    Hi

    "same kind of problems were there when i was working on windows"

    Maybe the problem is with the BIOS or motherboard, even the WiFi card itself.

    It may not be an Ubuntu or Windows problem, but it could be related to the router channel and amount of traffic/signals that are being transmitted in your neighbourhood.

    So please be prepared to do fault finding on your router as well.

    SOLUTION: Something tightened in cockpit.
