Thread: Can't access wep encrypted network with linksys wusb11 ver 2.6 net adapter

  1. #1

    Default Can't access wep encrypted network with linksys wusb11 ver 2.6 net adapter

    Hey, I have installed Suse 11.4 from the Gnome liveCD, and I "can" access my home network when it is unsecured, however, I can't access it when WEP is turned on. Now, I know that WEP is insecure but there are devices on the network that only supports WEP so the router settings can't be changed. Also just for testing purposes i have tried the WPA2 encryption method to no avail (dmesg reports that the connection timed out). The only encryption method that looks promising is the open-wep encryption. When trying to connect to the network (with open-wep turned on) I have performed a bit of checking to see what is going on, now I don't know much about in-depth linux and stuff but, below are the outputs from lsusb, dmesg, iwconfig, and ifconfig.

    I would really appreciate it if someone could shed some light on what's going on, and whether or not this is fixable.
    Thanks

    With WEP you have to use the whole hex key, usually 128bit
    Is that what you do?

    the key is a 64-bit key

    Not sure then.
    I'm no expert in this area, so hang around for them to respond.

    The driver for that 077b:2219 device is at76c50x-usb. The code says it handles
    WEP, and in fact your system authenticated and associated as shown in your dmesg
    output (your WEP Key is OK):

    [ 314.227524] wlan0: authenticated
    [ 314.641393] wlan0: associate with 00:17:9a:28:ea:6c (try 1)
    [ 314.644709] wlan0: RX AssocResp from 00:17:9a:28:ea:6c (capab=0x431
    status=0 aid=1)
    [ 314.644718] wlan0: associated
    [ 319.848103] ieee80211 phy0: wlan0: No probe response from AP
    00:17:9a:28:ea:6c after 500ms, disconnecting.

    Why the link went inactive after 5 seconds is not clear.

    To get some debugging output, do the following:

    Code:
    sudo /sbin/modprobe -rv at76c50x-usb
    sudo /sbin/modprobe -v at76c50x-usb options at76c50x-usb=0xF
    It may be necessary to get more debug output later, but let us start with this.

    After this I have to disconnect the adapter and reconnect it (a couple times). If i reverse the order of the commands i get no output for "sudo /sbin/modprobe -v at76c50x-usb options at76c50x-usb=0xF".

    I blew that with a bad copy and paste:

    sudo /sbin/modprobe -rv at76c50x-usb


    sudo /sbin/modprobe -v at76c50x-usb options at76_debug=0xF

    Pnce the driver has been loaded, you need to unload it before a reload produces
    any output.

    That was pretty clear. Leave the "options" keyword out of the command.

  10. Default Re: Can't access wep encrypted network with linksys wusb11 ver 2.6net adapter

    And I left out the "options" keyword, and got about the same thing again (just this time the "unknown parameter" is 'at76_debug=0xF'). If the purpose of this command is to simply reload the driver, sudo /sbin/modprobe -v at76c50x-usb seems to work
