Description Aleksandr Koltsoff (reporter) 2010-03-19 15:19:14 UTC
(Settings > General > About product)

DI-524 (AP) running V2.04 (2006-04-28) firmware.

(Explain in detail what you do (e.g. tap on OK) and what you see (e.g. message
Connection Failed appears))
1. While selecting a network that is WPA protected ("WPA-PSK/WPA2-PSK") N900
will prompt for a WEP key instead for a WPA passphrase. Not possible to enter
the passphrase (since it's not hex).
2. The icon shown for the network has only one lock (as opposed to WPA networks
that have two).

N900 should detect the network correctly and ask for PSK and then associate


Connection cannot be attempted since PSK is never asked for.

(always, less than 1/10, 5/10, 9/10)

Always, this is the third firmware that fails in an exactly the same way.

Associating to other WPA networks works (behind colubris APs). The one on
DI-524 fails.

Other devices connect to the DR-514 network without problems. Including N800,
N810, Wii, all kinds of laptops (windows and Linux), etc.




The network is not special in any way (not hidden etc).

s/DR-524/DI-524/. A typo.
Comment 2 Andre Klapper maemo.org 2010-03-23 17:31:25 UTC
That hardware seems to create quite some problems. Also see bug 9057 or bug
8638 comment 3.
Comment 3 Andre Klapper maemo.org 2010-04-07 19:55:44 UTC
Can you please provide a syslog? See
http://wiki.maemo.org/Documentation/devtools/maemo5/syslog and
http://wiki.maemo.org/Documentation/devtools/maemo5#Installation for more
If you are not used to Linux, after creating the syslog file you can copy the
syslog file to those folders that are visible in the Maemo File Manager by:
  * Starting X Terminal
  * cp /var/log/syslog /home/user/MyDocs/.documents/
After that you can find the file in the Maemo File Manager by going to Nokia
N900 > Documents.
Comment 4 Derek 2010-04-25 02:02:03 UTC
I was able to solve this issue by setting up the DI-524 to use "WPA-PSK" mode.
After that, the n900 correctly detects the WPA encryption.
If the DI-524 is set up with "WPA2-Personal" or "WPA-Personal/WPA2-Personal"
modes, the n900 wrongly detects WEP. I can see similar problems (at least with
the WPA2-Personal mode) using my ubuntu netbook.

Aleks, does this also work for you?

Not quite sure, but using WPA-PSK wouldn't have been an option anyway. I ended
up running to a store and got a newer AP and everything worked just fine with

I also noticed the same effect as Derek, newer Linux kernels don't work with
the AP-524. I'm thinking that some lower level parsing has changed to be more
strict in the kernel, or maybe some subsystem works differently now. I wouldn't
be surprised at all if the AP-524 broadcasts some evil stuff.

Given perfect universe I could probably retest and do some real over-the-radio
captures of the stuff that AP-524 sends, to detect what infact is the matter.
Maybe some day.. :-). Meanwhile, I don't have the time to test, sorry to say.

This week Nokia released the Maemo5 update version 10.2010.19-1 for public
(also called "PR1.2").
If you have some time we kindly ask you to test again if the problem reported
here still happens in this new version - just leave a comment (and feel free to
update the "Version" field to the new version if it's still a problem).
Comment 8 Andre Klapper maemo.org 2010-08-30 15:34:00 UTC
Aleksandr, is this still a problem in 10.2010.19-1?

Hi there, sorry to say, the D-Link device in question has joined our local
scrap-pile, so I won't be able to test. Maybe marking this bug as INVALID will
make it go away?

best regards, ak.

Ah, pity... but thanks for the update!
