Most times I reboot computer the network adapter disappears from file manager.  Takes several reboots to get it working.  I have uninstalled and update driver several times.  The HP PC Hardware Diagnostics UEFI - sp78036 says no wireless module installed when I run it.  This last time I refresh from boot then it's showing fine then again I on it its shows no WiFi connection then I did full format the then also its showing that's only after I check on component test WiFi module its shows  WiFi module not installed the image I am showing my product is out of warranty but in its show only problem please me this time. IMG_20190726_002005.jpg
