To begin, this issue has been present since the VERY first power-on. No BIOS or other driver updates created this issue as I had just received the laptop and have not done any. To be crystal clear, the laptop was shipped with this issue. A lot of the initial setup was skipped because the wireless adapter could not be found.
After a clean power-on the wireless adapter is ALWAYS present and working. Whenever the lid is shut for a period of time (Sleep for 5 minutes), the wireless adapter disappears and wi-fi is not available (Network Reset doesn't bring it back either). Even though wireless is gone, the Bluetooth adapter is still present, working, and available. Bluetooth and wireless are derived from the same Qualcomm Network Adapter Card. This, and the fact that the wireless ALWAYS returns after a clean shutdown, lead me to believe the network card is seated properly. The fact that the wireless adapter disappears after Sleeping\Hibernation leads me to believe there is a FW\Driver\BIOS issue with the power-down state during sleep\hibernation. Not sure if this is an AMD CPU issue or FW/Driver/BIOS but I'd appreciate any assistance you can provide. Having to do a clean shutdown every time I want to use wireless is getting old and makes for a terrible customer experience.
I checked all of the power settings and even went a few steps further. While I was able to see the wireless adapter I went into Device Manager and dove down into the options for the Qualcomm Bluetooth\Wireless adapter and unchecked to the box to allow the device to power down during sleep. Still didn't work. I went so far as to also modify the power option to allow PCIe devices (which the Qualcomm card is) not to power down during sleep as well. I'm really at a loss from what to do from an OS perspective. This smells highly of a Driver/Chipset/BIOS issue. Could also be an AMD CPU power-state issue that needs to be addressed.
Thank you for the tag details.
Please download & save the following drivers to your desktop screen.
1)Qualcomm Wi-Fi & BT driver
2)AMD Chipset driver
3)BIOS (1.5.0) Download this even if you have the latest driver.
Open device manager – network adapter – right click on the Wi-Fi driver & click on uninstall (check the box that says delete driver) Do not restart the computer.
Install the above drivers & then restart the computer.
Open device manager – expand network adapter – right click on the wireless driver – Advanced tab – Uncheck Allow this device to sleep (save power)
Open Power management – Wireless adapter settings – Plugged in & On battery should be changed to Maximum performance.
Let me know the outcome.
Sent a PM. In short, did not work. Also did a factory reimage and tried your suggestions. Issue persists.
One additional step I tried. I went into Advanced Power Options and modifed PCIe Link Power Management to be 'OFF'. Figured it was worth a shot since the network card is a PCIe device. Still did not work.
This could be an issue either with the Windows OS or the motherboard. I would request you to back up data & do a clean install. If the issue persists, I can assist you with the service options.
I know how to do a factory install but do not know how to do a fresh, or clean install of the O/S. Do you have a quick link to an instruction or a brief explanation how to do it? If it is in the same 'F12' menu as the factory image restore I can figure it out.
Please use a blank 16 GB thumb drive & use the Microsoft media creation tool from this link http://bit.ly/2nmvVhA .
Once you have the image follow the below steps to install Windows. Please note that doing this will result in loss of data.
