Problem wifi-Disabled Hardware

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Good morning,
I have a problem with my wireless, I have a Toshiba U840-10u.
When I install Fedora directly activate the indicator light that the connection is enabled.
After installing it is impossible to turn the wifi says "Hardware disabled", my network card is Intel Centrino Wireless N 2230.

To enable and disable wifi use the FN + F12 key, but does not work (all other function keys work properly). In windows if you press two times this key activates the wifi, three times activates bluetooth and four times off everything, both bluetooth and wifi.

I have read that a user disabled the bluetooth from the BIOS and then it worked, but I don't have the option to disable bluetooth in my BIOS.


  • When I run: rfkill list

0: hci0: Bluetooth

Soft blocked: no

Hard blocked: no

1: phy0: Wireless LAN

Soft blocked: no

Hard blocked: yes

  • Run “rfkill unblock 1” but does nothing:

1: phy0: Wireless LAN

Soft blocked: no

Hard blocked: yes


  • I have reinstalled the firmware
    yum install linux-firmware

yum reinstal linux-firmware


  • After this release the order to
    sudo modprobe-r iwlwifi
    I appreciated the following error:
    modprobe: FATAL: Module iwlwifi is in use.
    run:
    sudo ifconfig down wlp2s0
    And again:
    sudo modprobe-r iwlwifi
    But was still dating the same message:
    modprobe: FATAL: Module iwlwifi is in use.
    I launched:
    sudo ifconfig wlp2s0 up
    and gave me the following error:
    SIOCSIFFLAGS: Operation not possible to be disabled radiofrequency




I do not know how to fix it, I leave the configuration information below.
