Nokia versus Cisco

Hi,

I have for a customer testet a Nokia D211 Datacard also running Wlan. With
the card I can associate with many access point, but when I try with Cisco
access points it cannot associate. It is searching and searching but never
find the SSID or make a connection.

The Cisco access points that I have tried is:

Cisco 1242 with the standards 802.11g and (802.11a)
Cisco 1220 running 802.11b

Either of theese are working.

Have you heard about such a problem before? I cannot find any reference to
it on Internet - and that seems strange to me. (OK - it is an old Nokia
card - but anyway).

Best regards
Lasse

Are you sure the Cisco access points were broadcasting SSID? Could you
see them with other wireless clients?

Looks like the D211 had a problem with short preambles, so one workaround
would be to disable short preambles on the AP. Alternatively you may want
to see if you can find fixed code for the Nokia.

Hi,

We are aware of the problem with short preamples, so we do not use that.

And to John - We are also broadcasting the SSID and we can see the SSID with
other clients.

I'll assume Windoze XP Home on the Nokia D211 with the latest updates.
If you're running Vista, there are some nifty command line diagnostics
in netsh that can be used. Also, I keep running into XP SP1 wireless
systems that don't work.

Can other wireless clients connect to the two Cisco AP's?

Are you using WZC on the Nokia D211 to connect or some other
connection manager? If so, what's the name and version?

What happens when you run a wireless sniffer utility on the Noikia
D211 such as Netstumbler or Wi-Fi Hopper? Does that see the SSID's?

Some other possibles:
1. Nokia D211 set to ad-hoc only.
2. Cisco AP's set with MAC address filtering.
3. Cisco AP's set on non-US channels 12-14.
4. Short preamble (already mentioned).
5. Cisco AP's set to point-to-point or point-to-multipoint bridging
mode.
6. WZC is set to ignore the specific SSID's. There's some registry
trick to do that, but I can't find the reference.

Since the SSID's of the two Cisco AP's are known, try forcing a
connection with the Nokia as if the SSID were hidden. Then, look in
the Cisco AP's syslog output to see what's screwing up. I don't know
if the Nokia has a log output, but check that also. Finally, if
you're really a masochist, try enabling the Windoze Wireless
diagnostic output using:
netsh ras set tracing * en
net stop wzcsvc
net start wzcsvc
Look for log files in:
c:\windoze\tracing\
directory. There's quite a bit of output, but something should show
up in wzctrace.log.
