Device not able to re-establish the connection with the Wi-Fi Access Point. RRS feed

  • Question

  • Our windows embedded compact 7 device is connected to a Wifi enterprise network using PEAP authentication. When the device was placed inside the faraday cage the wifi connectivity is lost due to zero signal strength which is expected. If the device is brought out of the faraday cage in <= 5 minutes, it is able to reestablish the connection with the wifi
     network. However if the device is brought out of the faraday cage after 20 minutes duration, it is not able to reestablish the connection with the wifi network.<o:p></o:p>

    Please let us know how we can improve the performance of the wifi driver here by increasing this time out time. Possibly
    if there is any configurable parameter that has to be updated in [HKEY_LOCAL_MACHINE\Comm\CCWMXWIFI\Parms].

  • Yes, it is an issue that is probably fixed in later updates.

    I don't understand why the first thing you try when you encounter an issue is not install all latest updates.

    What do you think updates are for?

  • Are you building your kernel from a fully updated WEC7 tree? I remember some update that should've fixed this issue...

  • I changed jobs in July 2017, and no longer have access to the updates - but according to several posts in the forum, there have been a years worth of updates since June 2017.  So why did you say yes to having the latest updates?

  • You can read the release notes for the updates.  That is something that you should do on a regular basis, and then re-read them when a customer has a problem.
