Solved!

Noteboook doesn't find wlan anymore

HP Recommended
HP 255 G7 Notebook-PC
Microsoft Windows 10 (64-bit)

Hi,

 

the Notebook worked well. But now it doesn'f find the WiFi-Adapter any longer. The connection via Ethernet cable is ok. But if it is not connected, no network adapter is found. Windows could not solve the problem.

 

Best regards Nbdruck

Thank you Lil_Boy_Blue!

 

I opened the device manager and selected "WLAN Realtek RTL8821CE 802.11ac PCIe Adapter".

In "General" it shows me the device status:

The device could not be startet. (Code 10)

{Process failed}

The process could not be performed.

 

Now, I set the BIOS settings to the factory defaults and now it works.

Hi

Copy, Paste and Save in Notepad, as LBB.bat (not a .TXT) and double click to run.
Preferably run as an Administrator.
OR
Copy and use the individual command lines as needed.

Post anything non-personal, but relevant please.

@Echo OFF
getmac
netsh lan show interfaces
netsh wlan show interfaces
netsh wlan show drivers

PAUSE
systeminfo
PowerShell -Command "Get-NetAdapter"
PowerShell -Command "Get-NetAdapter -Name * | Format-Table -View Driver"
PowerShell -Command "GIP -Detailed"
PowerShell -Command "Test-NetConnection"
PAUSE

 

 

If in doubt please ask.

Thank you Lil_Boy_Blue!

 

I opened the device manager and selected "WLAN Realtek RTL8821CE 802.11ac PCIe Adapter".

In "General" it shows me the device status:

The device could not be startet. (Code 10)

{Process failed}

The process could not be performed.

 

Now, I set the BIOS settings to the factory defaults and now it works.
