Ideapad 300 15Isk Network Adapter Not showing in Device Manager

 -Ideapad 300 15ISK Laptop

-qualcomm qca9377 wireless network adapter

 

Trouble started after VPN install. Within 24 hours, no wifi networks were being discovered. Networks were tested and being used by other devices properly, including other laptops. The network adapter was showing up in the device manager for awhile. Then it was only showing after I selected " show hidden devices". I redownloaded the driver on a usb drive from another computer. I deleted the driver from laptop, and then reinstalled new driver. After I restarted the laptop, the device manager gave a code 45 on the network adapter ( devices is no longer connected to the computer) I restarted the computer again, and now the network adapter is no longer in the device manager, or hidden devices at all. Please help with troubleshooting!! Thank you!

Hello Kwyn

Thanks for using the Lenovo forums.


If you are able, Try to download the WiFi and Chipset drivers for the unit from the support page.

 

Make sure to reboot after an update on the unit.

 

If that doesn`t work, I would recommend that you refresh back to an older version of windows before the installation/update, and see if the issue persists.

 

If that doesn`t work, try to see if you are able to perform a factory reset on the device.

 

 

Hope this helps, let us know how you get on.
