My HP suddenly can’t connect to internet, other computers and devices are fine. Only my pc.

I tried many ways, like update the adapter, reset ip....it always shows the global icon on bottom left corner. It sometimes connects, but can not open the websites, sometimes doesn’t work. Now it shows faint signal and a lot of WiFi accesses are gone.

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

Run as a complete batch file if possible, else just copy and paste individual lines...

Preferably run as an Administrator.

C:\>PowerShell -Command "Get-NetAdapter -Name * | Format-Table -View Driver"
