    Exclamation Cant connect wifi (Centrino Wireless-1000)

    I'm a really noob, in this linux world, but i want to try it.

    The problem I am having is with my Toshiba Satellite L655-S5117 - Laptop. Windows 7 works fine. My distro flawless except wireless wont work. Can detects a wireless card, but can't use it(connect). Here are the specs.

    Welcome to the forums.

    Now, the output of

    Code:
    sudo lshw -C network
    Thanks. Your problem could relate to wireless N. Have you tried disabling it?

    Re: Cant connect wifi (Centrino Wireless-1000)

    You have 2 drivers running at the same time...might be conflicting with eachother possibly. Looks like you need the "iwlwifi" module. Have you tried removing the other?

    sudo modprobe -r rt2800usb

    Then removing the other and inserting it back in?

    sudo modprobe -r iwlwifi

    sudo modprobe iwlwifi

    then try again to connect using network manager

    Re: Cant connect wifi (Centrino Wireless-1000)

    Is rt2800pci loading because of a declaration in /etc/modules?
    Code:
    gksudo gedit /etc/modules
    If rt2800pci or any other rt2x00s are in there, remove them. Proofread, save and close gedit.

    Now in a terminal, do:
    Code:
    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 11n_disable=1 bt_coex_active=N
    If this helps you connect, we can write one file and make it permanent.

    I guess i'm running 2 drivers because im using a wireless usb adapter, the only way to connect right now.

    Im not sure, maybe is the driver of wireless usb adapter.
    I'll restart the laptop to use gedit. I'll post the result 2-3 min.

    Re: Cant connect wifi (Centrino Wireless-1000)

    I suggest you remove the USB and then try these commands:
    Code:
    sudo modprobe -r rt2800usb
    sudo modprobe -r iwlwifi
    sudo modprobe iwlwifi 11n_disable=1 bt_coex_active=N
    Then tell us if you are able to connect with the internal device only.
