Description Pete Black (reporter) 2006-10-30 23:59:24 UTC 
We have had major issues getting the Nokia 770 to participate in meshed
wireless
networks using WDS.

The 770 has been tried with 3 different Access points from Proxim (Atheros
chipset), Checkpoint (Atheros Chipset) and Linksys (Broadcom chipset), and
anytime WDS is used, the 770 suffers from random disconnects, usually within
seconds of association, followed by varying conditions depending on AP.

With the checkpoint, connection comes up, but seconds to minutes later,
'Connection Lost' appears on screen and the 770 drops its connection. Socket
connections during the connected period are extremely unreliable, though it
seems a constant ping helps to delay disconnect, and ICMP traffic seems
relatively unaffected.

With the proxim, connection comes up and appears marginally more stable than
the
Checkpoint APs but will often randomly disconnect after 1-5 minutes. Similar
TCP
socket instability is observed, along with ICMP keeping the connection up
longer.

With Linksys WRT54GLs running DD-WRT firmware, the connection comes up, and
seconds later is dropped, though the onscreen indicator indicates that the
connection is still present. No IP connectivity is available at all ,and a ping
command does not mitigate this condition. 

We have tested the final 2005 software, and the latest 2006 software and
observed similar, if not identical behaviour in all cases. We have tested with
multiple devices (we have a total of 32 Nokia 770s , and all we have tried have
shown this behaviour)

Multiple instances of 'eapd' are seen to be running in the top output.

Common to all these conditions is the following behaviour, monitored with
iwevent:

script used (testConnect signals libosso to connect a profile using the C API):
#!/bin/sh
/usr/local/sbin/iwevent &
./tuxapp/testConnect 'MeshTest' &
sleep 10
/usr/local/bin/ping 192.68.1.1

(Association, followed by backgrounded ping to AP IP, with iwevent output
interleaved)

Suffice to say that this is of major concern to us, as WDS meshing is becoming
more common, and is somewhat central to our project involving the 770s. 

Other devices such as laptops (e.g. my Apple iBook w/Airport Express Card and
MacOS X, a colleagues Dell w/Atheros chipset/madwifi drivers, another Dell with
inbuilt wireless running XP - do not exhibit this issue at all.)

It would seem a number of issues with APs, even in non-WDS mode are related, as
it seems the 770 generates large amounts of DEAUTH packets on the network,
followed by repeated attempts to reassociate, in some cases seemingly
unsuccessfully and often causing complete connection losses or TCP socket
terminations.

I have also observed a number of spontaneous reboots occurring after repeated
testing of these conditions. It would seem the drivers or firmware used to run
the Nokias Prism54 SoftMAC chipset have some issues.

What, if anything else, do you guys need from me to get a handle on this
problem?
Comment 1 Pete Black (reporter) 2006-11-08 10:50:17 UTC 
The latest 2006 release from maemo.org (e.g 2006 release update 1 as detailed
in
the november maemo-announce posting) seems to improve things a great deal.

Haven't had time to do detailed analysis, but WDS connectivity now works, and
if
the 'constant re-auth' issue is also gone, then it looks like Nokia might have
really come through for us on this one. 

Big thanks to anyone involved in addressing this issue

Pete, did you have any chance to retest this again against current maemo
software and hardware?
