  • Hi,

    WZC or wireless zero config is no longer supported in WEC7. Depending on what you need , you may use WLAN APIs or NDISUIO programming to achieve results.

    Native Wifi reference:

  • Hi balajit

    Thanks for response!!!

    Our main issue is that our wifi module that is connected to the board is always getting 169.254.x.x series IP with DHCP enabled and our hotspot having value for default gateway. Acc. to DHCP client server concept. The hotspot server should assign 192.168.2.x series address. But we are not getting that IP. That's why we want to proceed with WZC.

  • Hi,

    WZC has no role here. Neither has native wifi got a role (which superseded WZC). This seems more like a configuration issue.

    You may check the AP configuration / run wireshark to analyze DHCP issues.

  • Hi Pratap, If you are getting 169.254.x.x, means your WiFi module not connected to server. In adapter registry you can make AutoCfg = 0. No matter about server network mask, client will add and get server's network mask and server allocated ip. Check registry setting first using remote registry, as adapter settings are correct.

  • Balaji is correct, post your WiFi adaptor registry settings, that could help people to answer.

  • Dear Developers.

    Thanks for response!!

    I have checked in the adaptor registry settings and there was no AutoCfg entry then I created one entry and I saw no change for IP. Still I am getting the same IP what I had mentioned above.

    The adaptor registry settings are as -

  • Dear Vinoth,

    Thanks for reply.

    Nopes, I have not tested the above links, I will test and reply back. But one more thing I would like to discuss that upto so far we never update WINCE7.

  • Dear Developers,


    Out of the mentioned four links. I selected the one link according to my requirement as -

    After updating the WINCE7 I followed the steps but now I am getting the following exception-

      84726 PID:400002 TID:3d10002 Exception 'Data Abort' (0x4): Thread-Id=03d10002(pth=9e42f180), Proc-Id=00400002(pprc=83c4f5e0) 'NK.EXE', VM-active=019c000a(pprc=9e41148c) 'shell.exe'
      84727 PID:400002 TID:3d10002 PC=aded93e4(rwlpsdio.dll+0x000293e4) RA=adedec50(rwlpsdio.dll+0x0002ec50) SP=aaedf038, BVA=adfb8a10

    for some time I was thinking the issue may be related to H/W, but after then I flashed the older images and i confirmed that it was working fine. Now, the issue is above exception..

    What will be the best way to solve the above exception???


    First of all good to see you on this forum.

    I have seen the link what was shared by you. But, after deep analyses I observed that there is no information about my issue.

    But Thanks for sharing the link..

  • Hi,

    What is rwlpsdio.dll. Is it the wireless NIC that you are running?. Is yes, then there could be issues with the driver itself.

    Have you tried assigning a static IP to the wireless interface and could you ping the device on the wireless interface?.

    This should be your first check to see if the driver is really working (if the send and recv handlers work), the driver handles packets properly or not.

  • Dear Balaji

    Thanks for reply.

    I am getting this exception when I inserted the Wifi module in the SDIO slot and after that immediately I am getting this issue. Now, the H/W is not initialized yet.

    What is rwlpsdio.dll. Is it the wireless NIC that you are running?. Is yes, then there could be issues with the driver itself. 

    Yes, this is the wifi driver dll. From my point of view there is no issue with the driver because the same driver was working with Static IP, before updating the Wince 7.

  • Hi there

    I'm porting some wifi driver / wlan code from CE6 to WEC7.  The interface has changed from wzcsapi to wlanapi. 

    My question is, is there an equivalent call to the WZCRefreshInterface call in CE6?

  • Hi Royston,

    WZC is not available in WEC7. Maybe the discussion in this thread will help you.
