Network adapter not found after waking up from sleep

[Arjun_RK]

My laptop is just 2 weeks old and I am experiencing some driver issues in windows 10 after turning the system back on from sleep. When I turn it back on from sleep, I can no longer connect to WiFi since the WLAN driver is found missing and Windows doesn't recognize that the laptop has a WiFi adapter. Troubleshooting would just say that WiFi is not supported on my device. I observed this happens with bluetooth adapter as well. When I look in the Device Manager, I can no longer find the WiFi adapter (Realtek RTL8822CE 802.11 ac PCle adapter in my case). I have to restart the computer everytime this happens, in order to reconnect to the Wifi. I tried a few common solutions like updating/rollbacking drivers, I found on internet and it doesn't seem to help. I tried a solution which suggest that I disable "Allow the computer to turn off this device to save power" in the Power Management Tab in Device manager. But I cannot find this tab (I believe it's removed for newer versions of Windows 10?). So the problem is still unsolved. I am dual booting Ubuntu 20.04 alongside Windows 10 and there seems to be some issues with sleep in Ubuntu as well. Sometimes, the computer doesnt even turn on from sleep in Ubuntu. Would dual booting have anything to do with these issues?

Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

1. In Windows, search for and open the Device Manager.

2. Click the arrow next to the device that needs to be adjusted.

   • To check the keyboard settings, select Keyboards.

   • If you are using an optical mouse, select Mice and other pointing devices.

     NOTE: If you prevent the mouse from being able to wake the computer, you can still wake the computer by pressing the Space bar on the keyboard or the Power button on the front of the computer.

   • If the computer is using an "always-on" Internet connection, select Network Adapters.

   • To check the high definition audio settings, click Sound, video, and game controllers.

3. Double-click the name of the device to open the Properties window.

4. Click the Power Management tab.

   • If the Power Management tab is not available, click the Change Settings button. The same Properties window opens with the Power Management tab available.

   • If you are prompted for an Administrator password or confirmation, type the password or provide confirmation.

5. Deselect the box next to Allow this device to wake the computer.

   

6. Click OK, close any open windows, and then restart the computer.

7. Repeat these steps for additional devices, if needed. You might need to do this for each of the devices listed: mice, keyboards, network adapters, and sound.

Hope this helps! Keep me posted for further assistance.
