Additional help on WiFi needed

[blevo]

I'm having trouble getting my usb device working properly. Or rather I'm having trouble getting it and Linux to play nice together.

I'm working with Cassandra and it will recognize that I have my wireless device in. Well, from the GUI everything seems to be working but I don't have any choices under 'wireless networks' and if I 'choose other wireless' and put in all the details it just says 0%

It does the same now that I've made sure I have the prism driver installed using ndiswrapper.

After removing my ethernet connection and running mintWifi.py this is the output:

can someone help me sort this out? and also translate that which is supremely relevant in the output as well, so I might learn something in the process

Thanks for reading

oh, and another weird thing, on the graphical wireless driver tool (ndisgtk? or ndiswrapper) it says "Hardware present: No" even though the d-link usb is in. and in the daemon.log it says "NetworkManager: <WARNING>^I nm_device_802_11_wireless_set_mode (): error setting card wlan0 to Infrastructure mode: Operation not supported"

Ok, so I followed part of this tutorial
http://www.linuxforums.org/forum/linux- ... post470915

The "problem" section of the tutorial. and after the final modprobe ndiswrapper everything clicked and it asked me the keyring thing and Voila! worked. I was pretty stoked... That is until I restarted my computer.

Now what happens is this: I'll boot up Cassandra and it won't recognize that my d-link DWL-122 usb device is even plugged in (even though the device is receiving power and both lights are solid). Not listed under lsusb. I physically unplug and plug it back in.

Code: Select all

lsusb 

-- it shows up but the network manager doesn't see it. I type

Code: Select all

sudo modprobe ndiswrapper 

and things click and I'm prompted for the keyring password. Everything works.

Now, how can I make it so it works from the get go without having to do the modprobe-ing? Do you think it's just a finicky usb device? Don't remember having this issue in winXP so I'm relatively sure it's not the device. Perhaps the usb controller, not sure how those work.

looks like the usb module is being a bit daft.

you could modprobe the usb module (may be more than one) to remove it and insert it again to rescan for usb devices.

I have seen similar problems with usb devices.

You could try:

sudo /etc/init.d/hotplug restart

if not, then the new way is:

sudo /etc/init.d/udev restart

That should force a re-scan.

Sorry, I am not very familiar with debian. In slackware, you would add this line to rc.modules:

Code: Select all

/sbin/modprobe ndiswrapper

I searched for it by hand (I'm using the xfce edition and I can't find a search function), but I could not find it or an equivalent file. Maybe someone else can help out.
