Hello to all,

I have such a question: Is there any posibility to soft change MAC ADDRESS of my WiFi card? I use Winzard WIZA200 G4.
I am under a Network coverage at work, but access points have an ALLOW LIST by MAC ADDRESS, so I can't connect.

Thank you in advance for every reply.

you mean you have access to the filer lists of ok mac's ?

and if you change your mac to another which is valid what would you do when the other nic with that mac connects ?

Yes, because I'm IT there :) , but don't have access to access points :mad: . Therefore all wireless devices I monitor :rolleyes: .

As I supply/repair device's, I always know which MAC address is free for use. ;)

Isn't the mac address normally stored in the wifi chip's eeprom or equivalent?

Hello,

I'm not programer for Pocket PC. I don't know where to find the MAC address for PocketPC, but I suppose that is stored in WiFi chip.

What is clear for me, that MAC is not stored in Registry .. at least in free text mode.

@Rudegar: It can't be changed like in Windows like system.

yes it's stored / hardcoded in the nic
both on windows and in pda but on windows at least
it's put in the registry and can be masked there
if thats not dont in windows mobil and the nic is requsted each time
the os need it
one need to capture all msg's asking for the mac and that's a bit of possible complex programming if the os never use it and the nic itself just add it to the packets there is no way to change it

Here's a link where someone explains how they got it to work.

Thanks a lot Chris & Paul,

Finally changing MAC on the fly is working .

Here are the steps I followed(just detailing them incase someone needs)
Step 1 --> changes to driver
Steps [2-5] from C# application

1) In NDIS Intermediate driver (QueryMiniport function), I made the
following changes
a) When OID is CURRENT_MAC_ADDRESS , open registry , read a
registry name ChangeMAC,
b) if value of ChangeMAC is 1 then read registry value of "NewMAC"
and then convert it appropriately to MAC format
(remove extra unicode characters etc)
c) then do a NDISMoveMemory to current adapters MACaddr field.
d) close registry

2) Set value of ChangeMAC (DWord) to 1
3) Set value of NewMAC (string) to the new mac address
4) Invoke a NDIS_REBIND_ADAPTER (this internally will call
QueryMiniport ) and inturn execute step (1)
5) Set value of ChangeMAC (DWord) to 0

Once again thanks Chris and Paul.

@Setok: Thanks for your research. I will pray for method to work ;)

@5n0rk: Thanks to copy paste the article right-here. not spending lot of traffic :)

@vijay555: Are you able to release the steps described above in C++ or C# like it is explained?:rolleyes:

How I understand from all that thread.. first we should change original drivers to a specific one which looks for macAddress in registry. And then to change the MAC in registry.. or with a program.

I have an 8525 that has a wiped eeprom, could I use this method to fix it?

If you are the manager for the Wireless AP's, would it not just be easier to add the MAC address of your device to the allowed list?
