I have here a wn220 (a.k.a. WRUB-2011i, by Ashton Digital), which is a Prism 2 device. Before, to get it running in my ubuntu 7.10 laptop, I would use linux-wlan-ng, which I installed using synaptic:


raub@monaco:~/todo$ wlanctl-ng version
wlanctl-ng: 0.2.9
raub@monaco:~/todo$


raub@monaco:~$ sudo wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
message=lnxreq_ifstate
ifstate=enable
resultcode=success
raub@monaco:~$

But, after doing a few updates using the update manager, it now acts like it does not know about this device anymore:


raub@monaco:~$ sudo wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
wlanctl-ng: No such device
raub@monaco:~$

Any reason it could be ignoring me like that? Here are the relevant dmesg lines:


[ 281.924000] usbcore: registered new interface driver prism2_usb

[ 1822.264000] usb 2-1: device not accepting address 9, error -71


To me it sounds like the usb device and the laptop do not like each other anymore but so far my google-fu has not been very fruitful. Any suggestions? I will try it in my OSX laptop just to make sure it is still happy.

Resurrecting this old thread of mine, do I still need to deploy linux-wlan-ng to make a prism2 card to work under 8.04 or it should work out of the box?

Update: it seems one the wires that went from the USB connector to the board broke off because of the hinge design:

So, I found some old/broken USB device, cut its cable, and soldered it as a replacement to the old hinge thingie:

So, I tested it and it seems to work. Now it is just a matter of making it all fit on its original case and life will be good.
