Windows Zero Config and a Cisco LMC352

Hi All,

I have a Cisco LMC352 conneccted to a device running Windows CE .NET
4.2 on a MIPS II processor.

The Wireless network works first time it is configured.

If I save the registry then restart the board then the configured
wireless network can not be connected to.

Windows Zero config displays trying to connect to Adhoc network. My PC
shows that it is connected to an unknown network, the Windows CE zero
config dialog shows that
it is connected to an Adhoc network but that Signal strength shows "No
Signal".

I have searched this newsgroup for any hints on what could be the
problem and I have tried previous solutions,
such as setting the Registry key "MasterKeysInRegistry" to 1.

If I reboot the device, disable the WiFi card in the NetUI and delete
the Zero Config registry keys then reenable the WiFi Card, Zero Config
allows me to reenter the network details and make a new connection.

Is there any way of setting up Zero Config so that it can reload the
network configuration on startup or will I have to write some code to
emulate the disable/enable of the wifi card and the deleting of the
registry keys? The final solution has to run without any user
interface so I need to be able to do it all via software at startup.
Anybody have any ideas?

Graham.

I'd suggest building a debug version of the OS and capturing the messages
being sent to the debug serial port/Platform Builder. There may be
something there which points you to the right place. You're confident in
the persistent registry that you are using? You've captured the device's
registry a) before WZC and b) after and then, c) after the reboot, verified
that the registry is set the same at c and b?

Graham, I suppose restarting the board means cold boot?
ZeroConfig uses the device key created in cold boot for WEP key encryption,
hence if only the registry persists in teh cold boot and a new device key
is generated, it won't work.

hello Soemin

I'm on the same point as Graham!
Do you now any possibility to automaticly configure the Wifi-Card after a
cold boot?
My system has to communicate with a AP (if possible using a WEP Key of
104Bit's)without any intervention of the User.
I'm using Version 4.20

thanks for Your help

Martin, check out \public\COMMON\oak\drivers\netsamp\wzctool.
It's a sample on how to configure ZeroConfig preferred network entry that
you can make it launched in cold boot.
