    Question Ralink wifi usb stick can't be verified automatically when Ubuntu start.

    Now i can use the ralink wifi usb stick(i got help at http://ubuntuforums.org/showthread.php?t=2147236, thanks Chilly and Bucky Ball), but every time i start ubuntu, it can not identify the usb stick automatically. the "Enable wireless" option in the internet icon is shut down automatically. I have to plug the usb stick out and plug it in, then it will work. How can i solve it? Thanks.

    Please open a terminal and do:
    Code:
    sudo su
    echo rt2800usb >> /etc/modules
    exit
    Now does it work as expected?

    No, it did not work. When the ubuntu starts, the "enable wireless" option in the Internet panel is not choosed. I still have to select the option and plug the wifi usb stick out and in.

    Please restart your computer. Before you do anything else, please run:
    Code:
    dmesg > zhengtao.txt
    lsmod >> zhengtao.txt
    iwconfig >> zhengtao.txt
    Start your wireless. Find the text file zhengtao.txt in your user directory and paste it here and give us the link in your reply: http://paste.ubuntu.com/

    Thanks.

    The driver is loaded but the card is "off". Check
    Code:
    rfkill list
    Please also check in your BIOS if the network starts before the OS

    The wireless is enabled in the BIOS.
    When Ubuntu starts, before I do something-
    0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
    1: ideapad_wlan: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
    2: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no

    After I choose the "enable wireless" in the Network panel-
    0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    1: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    2: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no


    And after I plug the wifi usb stick in and out-
    1: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
    2: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
    3: phy1: Wireless LAN
    Soft blocked: no
    Hard blocked: no

    Strange, its renaming phy0 to phy 1. Try "sudo rfkill unblock all" directly after booting with stick plugged.

    zhengtao@android-AAA:~$ sudo rfkill unblock all
    sudo: unable to resolve host android-AAA
