    3Com PCMCIA: Error for wireless request "Set Encode&quo


    Hi folks,

    I'm trying to get a 3Com AirConnect PCMCIA network card to work on my Toshiba Tecra 8000 notebook. I just installed SUSE 9.2 and prior to this I had Mandrake 10.0. I had managed to get everything working under Mandrake, but now when I try and connect I get the following message during boot up:

    ERROR: command 'iwconfig eth0 key off' returned
    Error for wireless request "Set Encode" (8B2A) "
    Set failed on device eth0 ; Operation not supported.

    ERROR: command 'iwconfig eth0 key open xxxxxxxxxxxxxxxxxx' returned
    Error for wireless request "Set Encode" (8B2A) "
    Set failed on device eth0 ; Operation not supported.

    I've searched using google and have seen that many others have had this message, but there has been nothing that tells me what I have configured incorrectly, and how I should fix it.

    I suspect that the system sees eth0 as a wired card, and hence why it doesn't recognise the wireless extensions. However, I don't know how to solve this. I have configured it all under YaST, and have selected wireless and pcmcia, but this has been to know avail. I am trying to connect to a billion modem 743GE and using DHCP.

    Please, any suggestions here would be really appreciated.....

    Running ifconfig and iwconfig gives:
    #ifconfig

    Also, I notice that when I shutdown, it fails on shutting down the PCMCIA _core module, it reports it is in use. It seems it the ds module (whatever that is) is running.

    Help..... please...


    Many thanks,

    Hi All,

    Well it has taken me a few days of pure frustration and investigation, but I now have it working. The answer, it seems, is that the 3COM AirConnect card wasn't supporting WEP. Thus, when the iwconfig eth0 key off command was sent, it didn't recognise the parameter key, and the "Operation not supported" message was posted.

    The solution was to upgrade the firmware on the wireless card so that it supported WEP. My suggestion (for what that is worth) check whether your network card supports the command that it is failing (especially if it is an old card), it most likely needs a firmware upgrade, or it is, as a long shot, thinking the wireless card is wired!!!!
