If it's a Prism card, dont't use iwconfig for setting the SSID, but use the following instead:
Code:
 wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
 wlanctl-ng wlan0 lnxreq_autojoin ssid=SpeedStream authtype=opensystem
 ifup wlan0
 pump -i wlan0
Of course, you should use your own SSID instead of "SpeedStream"
