Getting dscape running

Getting dscape running

[Jon Smirl]

I'd like to get a basic connection working on my system so that I can
check out the dscape stack and do some work on it. I am targeting an
embedded system using USB dongles but right now I am working on my
desktop. Hopefully this new list can provide the guidance that I need.

I have NetworkManager from CVS and the current version of
wpa_supplicant running. Hardware is a rt2570 dongle using the dscape
stack. OS is Ubuntu.

When I use NetworkManager to switch to the wireless device it fails.
It says the access point is unencrypted when it is running actually
WEP. The problem is probably caused by the NULL gobject reference.
What's causing this?

Have you confirmed you are able to connect using iwconfig manually instead 
of Network Manager ? Are you able to get associated ? 

I assume you are using the rt2500usb.ko driver, but can you confirm 
you are using a recent CVS tarball ?

I'm using rt2500usb from the wireless-dev tree.
I'll pull from CVS and try your most recent code.

This is part of what makes working on wireless hard, the pieces are
scattered everywhere.

It would be helpful if you could provide a debug trace as well.

Probably best to move this discussion to rt2400-devel and let us check
if the problem still exists in our latest CVS. From there, if assoc
is working fine you can bounce over to the NetworkManager list and go
from there.

ralink CVS won't build with the current wireless-dev tree.
It tool a little while to check since I had to rebuild my kernel and
turn debugfs on.
I'll try Pavel's suggestions next.

The mailing list for NetworkManager is networkmanager-list@gnome.org,
the website is http://www.gnome.org/projects/NetworkManager/

I believe this list is about the kernel part of wireless support.  If
you track the issue to the kernel, then please post here.  Don't forget
the kernel messages and more details about the kernel.

If you want a basic connection with WEP, you can try to use iwconfig.
Please make sure to set the channel, the AP (BSSID) and the ESSID.

You can also run wpa_supplicant from the command line.  wpa_supplicant
would find the AP for you.

Here's the same rt2570 device using the ifconfig commands. I was
trying to get NetworkManager running on it in case it was doing
something that I wasn't doing manually. Some is not quite right with
the WEP exchange.

I'm unable to connect to it using WEP. The same device works on the Intel stack.

It would be interesting to look at the iwconfig output at this point.
If "Link Quality" is still 0, there is no much use in running dhclient.
Run iwconfig as root so you can verify that the WEP key is correct.

And how about connections without WEP?

My understanding of the code that prints the above is that either the AP
doesn't support WEP or the client doesn't have WEP enabled.  That can
include the case when some other encryption algorithm is active.

Just in case, please make sure your .config enables CONFIG_CRYPTO_ECB
and CONFIG_CRYPTO_ARC4.

I think I've located what the problem is. NetworkManager was hanging
around as a deamon and changing my encryption settings improperly
(turning off WEP) probably because of the NULL gobject problem. I
fixed my system to not run NM, rebooted and now I can connect. I'll
just get rid of NM since it is not needed for my application. Turning
off encryption gave me enough clues to blame NM.

d80211 selects ARC4. ECB is selected too if you have Linville's last update.
