WiFi Adapter missing after Windows update, AGAIN

[ajayb8412]

I have a HP Spectre laptop which has been working fine until a Windows 10 update happened. Now the WiFI adapter (Intel 8265) is not installed (gives Code 56 error when I view in Device Manager). There is a yellow exclamation mark in front of the device. I have tried uninstalling, disabling, updating driver (also used the Intel tool to update driver). Nothing works. I used the Intel site to update driver, I used the HP support site to update driver....no luck. Code 56 error remains with the WiFi network adapter. I tried recovery which managed to get it to work again for 7 days and the update happened again. Stopped working. Very frustrating. Even a USB to Ethernet adapter cannot be installed (same code 56 error and the yellow mark in front of the device). Only thing that works is a USB to LTE dongle so I can get some internet access. I have tried all sorts of rolling back drivers, deleting and installing drivers (pretty much everything that is on the internet!). The WiFI adapter hardware must be good since it works when one of the recovery mechanisms work so does not look like a hardware problem. Can anybody help me with this? Really need the WiFi to work. In Network and Internet Settings, under Network adapters, I only see the Bluetooth adapter. No WiFi adapter. Also, hopefully once I get it to work again, how do I permanently disable ANY driver or Windows update? Very frustrating. Thank you for your help.

Hi

Does the F12 Aeroplane mode show?

HP Spectre, Windows 10 (updated since the WiFi adapter disappears as it gets updated), Intel 8265 Network adapter

System SKU 2LU96UA#ABA

What is interesting is that I cannot even get a USB to Ethernet adapter to work (same error).

Airplane mode shows but now it does not show WiFi sign.  Only bluetooth.

Also in the event log I see this:

Device PCIVEN_8086&DEV_24FD&SUBSYS_90108086&REV_78\4&2dbe3f31&0&00E1 was not migrated due to partial or ambiguous match.

Must have happened either when I tried to uninstall and reinstall the adapter or when Windows updated.

Yes, tried the driver from intel site and from HP site.  Looks like the driver is not installing at all (code 56).

Also this is in the event log.

Device PCI VEN_8086&DEV_24FD&SUBSYS_90108086&REV_78\4&2dbe3f31&0&00E1 was not migrated due to partial or ambiguous match.

I wonder if there is something wrong with the Windows side and not in the network adapter side

Hi

http://partsurfer.hp.com/Search.aspx?searchText=2LU96UA

does not list any Wi-Fi adapter.

That may be the reason.

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
msinfo32
PAUSE
systeminfo
PowerShell -Command "Get-NetAdapter"
PowerShell -Command "Get-NetAdapter -Name * | Format-Table -View Driver"
PowerShell -Command "GIP -Detailed"
PowerShell -Command "Test-NetConnection"
PAUSE

That should ID the adapter accurately.

For sure there is the Intel 8265 network adapter.  Has been working for over a year till Microsoft decided to update something and it has been downhill since then 🙂

The lbb.bat confirms that there is no adapter because the driver is not loaded (remember the code 56 error).  That is the whole problem!  How do I get the drivers to load and the laptop to figure out that there is this Network adapter and use it.
