Hello,

I am trying to get the Trendnet TEW-424UB to work. I have hardware
version 3.1R which is based on the Realtek RTL8187B chip. I got the
latest wireless-testing git version. I added the Trendnet PID & VID to
drivers/net/wireless/rtl8187_dev.c (shown below) but I still can't it
to work.

static struct usb_device_id rtl8187_table[] __devinitdata = {
        /* Realtek */
        {USB_DEVICE(0x0bda, 0x8187)},
        /* Netgear */
        {USB_DEVICE(0x0846, 0x6100)},
        {USB_DEVICE(0x0846, 0x6a00)},
        /* HP */
        {USB_DEVICE(0x03f0, 0xca02)},
        /*Trendnet Vendor=0bda ProdID=8189*/
        {USB_DEVICE(0x0bda, 0x8189)},
        /* Sitecom */
        {USB_DEVICE(0x0df6, 0x000d)},
        {}
};

When I plug the adapter in I get this under /proc/bus/usb/devices

The only other time I used wireless stuff under linux I used a distros
built in tools, so I hope I'm doing the config correctly. Here is what
I'm doing:

/sbin/iwconfig wlan0 key restricted MYKEY essid "ssid"
/sbin/ifconfig wlan0 up
/sbin/dhclient wlan0

Now #/sbin/iwconfig gives me this:
wlan0     IEEE 802.11  ESSID:""
          Mode:Managed  Frequency:2.412 GHz  Access Point: Not-Associated
          Tx-Power=27 dBm
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B
          Encryption key:XXXX-XXXX-XX
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

I am using Fedora 8 on a x86_64 system. My initial goal in all this
was to get the adapter to work with my embedded linux project
(http://opencircuits.com/Linuxstamp), but when it didn't work there I
figured I'd try it on my host machine.

Has anyone else gotten the TEW-424UB to work?

thanks
Paul
