I just bought a D-Link DWL-G122 WLAN-USB-Adapter and made it work with ndiswrapper. I need WPA-PSK with TKIP which works quite fine if I start up everything manually. The automatic startup at boot does not work because of two problems:

  • On startup the system hangs and syslog says
    Code:
    usb 1-1: reset high speed USB device using ehci_hcd and address 9

    Repluging the stick helps sometimes (not always)
  • wpa_supplicant does not start up as it should I configured /etc/wpa_supplicant.conf as follows
    Code:
    ctrl_interface=/var/run/wpa_supplicant
    ctrl_interface_group=wheel
    eapol_version=1
    ap_scan=1
    network={
            ssid="MyWLAN"
            scan_ssid=0
            proto=WPA
            key_mgmt=WPA-PSK
            pairwise=CCMP TKIP
            #pairwise=TKIP
            group=CCMP TKIP WEP104 WEP40
            #group=TKIP
            psk="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
            priority=2
    }

    /etc/conf.d/wpa looks like this
    Code:
    # List of interfaces
    INTERFACES="wlan0"

    # Common arguments to all wpa_supplicant instances
    ARGS="-w -d"

    # Interface specific arguments
    ARGS_wlan0="-Dndiswrapper"


Starting up wpa_supplicant on the shell does work fine, automatic startup seems not to work because there is no entry of wpa_supplicant in /var/run

Another problem, although not Linux specific, is that the stick does not find the access point if it is hidden. Perhaps someone has an idea about this issue, too?
Has anyone experiance with this USB WLAN-stick and solved these problems already?

After using an USB 1.0 port the stick works without problem. Additionally I added "-c/etc/wpa_supplicant.conf" to /etc/conf.d/wpa_supplicant

Seems to be a problem with the USB drivers for EHCI?!

I just had success with this as well. The drivers were downloaded from:

http://support.dlink.com/products/view.asp?productid=DWL%2DG122%5FrevB#

Code:
emerge ndiswrapper


Find the NetRTUSB.inf file.

Code:
ndiswrapper -i NetRTUSB.inf
ln -s /etc/init.d/net.lo /etc/init.d/net.wlan0
/etc/init.d/net.wlan0 start


I had a working config file for wireless tools... so I didn't have to reconfigure.

That is the trick: you are using the Winblows driver with ndiswrapper. The wrapper "translates" the driver so that it works with Linux.
