    Question Error for wireless request "Set Frequency" (8B04)

    I have my wireless enterasys card in managed mode and i load its interface eth1 during booting with a static ip. When i try to change the channel to 11 or frequency to 2.462GHz i get the following error.

    [root@monaco ~]# iwconfig eth1 freq 2.462G
    Error for wireless request "Set Frequency" (8B04) :
    SET failed on device eth1 ; Device or resource busy

    [root@monaco ~]# iwconfig eth1 channel 11
    Error for wireless request "Set Frequency" (8B04) :
    SET failed on device eth1 ; Device or resource busy

    Has anyone seen this before?What is happening?

    (2.6.16-1.2080_FC5)

    You might need to bring the interface down in order to do that.

    Code:
     ifconfig eth1 down
    iwconfig eth1 freq 2.462G
    iwconfig eth1 channel 11
    ifconfig eth1 up
    My crime is that of curiosity. My crime is that of judging people by what they say and think, not what they look like. My crime is that of outsmarting you, something that you will never forgive.

    Trickster thanks for your post.

    It doesnt work even if i take it down:
    ifconfig eth1 down
    ifconfig eth1 channel 11
    Error for wireless request "Set Frequency" (8B04) :
    SET failed on device eth1 ; Device or resource busy
