    Wifi adapter disappears after sleep; recognized after battery removal

    edsager

      Hello All:

       

      I upgraded the wireless adapter in my Sony Vaio VPCF23EFX with the Intel Dual Band Wireless-AC 7260.

       

      I covered Pin No. 20, but because I do not use bluetooth, I did not cover Pin No. 51.

       

      All went well with connecting until my laptop went to sleep.  After sleeping, I often (though not always) get the following:

       

      1. Notification that I cannot connect to the Internet until I plug in an Ethernet cable.

      2. The wireless adapter can be seen in Device Manager only when viewing "Hidden Devices."

      3. No wireless adapter is recognized as connected to the laptop..In fact, the little green light that comes on when the wireless adapter is recognized is not on until the wireless adapter is recognized again.

      4. Uninstalling and reinstalling with a couple of restarts sometimes causes the laptop to recognize the wireless adapter. (Installed manually via Device Manager and also via downloaded Intel PROSet/Wireless Software and Drivers. When installed manually, Windows 10 installs driver v.18.33; when using the Intel software download, v.18.40 is installed.)

      5. When No. 4 above does not work, shutting down the laptop and taking out the battery seems to cause a re-recognition of the wireless adapter.

       

      Questions:

       

      1. Should I cover Pin No. 51 even though I do not use bluetooth?

       

      2. Is there something I am missing with the steps I take to get the wireless adapter to be recognized?

       

      3. Is there a reason why taking out the battery (which is in good condition) would cause a re-recognition?

       

      4. Is there a place where I can download the drivers only for this wireless adapter (not the entire 100+ MB driver + software)?

       

      5. Any other suggestions?

       

      Thank you,

          We understand you have replaced the original wireless adapter for the Intel® Dual Band Wireless-AC 7260. Before we go any further, we would like to inform you that Intel does not support integration. You can learn more about this matter by accessing this link: Regulatory Information Regarding Hardware Installation or Upgrade

           

          1. Should I cover Pin No. 51 even though I do not use bluetooth?

          As for the procedure informed about isolating pin 51, this is not supported by Intel either, and if you decide to do so, it is at your own risk but, please know that such procedure may cause damage to the adapter.


          2. Is there something I am missing with the steps I take to get the wireless adapter to be recognized?

          Since this is an integration, it may be that your system is not meant for this wireless adapter as the computer manufacturer always customizes the adapters by adding/removing or even changing features and voltage in order to be fully compatible with the type of system they offer.


          3. Is there a reason why taking out the battery (which is in good condition) would cause a re-recognition?

          Our adapters were designed to work efortlessly without removal of any physical part from the laptop. We highly recommend to contact the computer manufacturer for further assistance. For you convenience, here is the link where you can find your computer manufacturer contact information: Computer Manufacturer Support Websites


          4. Is there a place where I can download the drivers only for this wireless adapter (not the entire 100+ MB driver + software)?

          Yes, there is. You can go to this link: Download Intel® PROSet/Wireless Software and Drivers for IT Admins

            aleki_intel:

             

            Thank you for your response. I was not expecting someone from Intel to reply. Thank you for taking the time and effort to do so.

             

            I am familiar with the Regulatory Information Regarding Hardware Installation or Upgrade and I realize that isolating pin 51 is not supported by Intel.

             

            I have contacted Sony, but they no longer are in the business of laptops, so they will not assist. Nonetheless, previously, I was made aware that upgrading a component (specifically the wireless adapter) was not verboten for the Sony Vaio. One reason I purchased the Vaio is that there were no proprietary parts that I might want to upgrade.

             

            Thank you for the link to the driver-only download and for the other links. Very much appreciated.

             

            I appreciate your analysis of this situation; I guess I was hoping for other users to reply with their experiences.

             

            If there are users who come across this, could you please share your experiences (unless, of course, it is against the Rules of this Community).

             

            Thank you,

            P.S. Do you know what US Government agency is responsible for implementing the regulations concerning hardware installation or upgrades? Or maybe the cite to either the section(s) of the US Code (USC) or the Code of Federal Regulations (CFR) which cover the regulation of hardware installation or upgrades?  That would be very helpful.

                  Dear richardsonkane75:

                   

                  Thank you for your suggestion. Unfortunately, however, in my situation, the computer does not recognize that a WiFi adapter is connected. Only a wired connection is seen by the OS.

                   

                  When my computer has recognized the wireless adapter as being connected, I do make sure the "Allow the computer to turn off this device to save power" check box is not checked.

                   

                  I did find a solution: the computer never goes to sleep and I rarely restart the computer.

                   

                  When I close the laptop lid, the computer shuts down.

                   

                  When the computer demands to restart due to installed updates, I allow it to do so, after which I turn off the laptop and then turn it on again.

                   

                  All is well after that, especially with the quick boot of Windows 10.

                   

                  Thank you,
