Losing Wi-Fi AFTER Sleep

Occasionally [ NOT ALL the time ], I have TWO problems, one of which I have a workaround for [ Problem 1 ], and the other is at present unsolved [ Problem 2 ], but BOTH occur after waking from sleep, whereby the Wireless Icon in the Taskbar shows as a globe [ NO Wi-Fi and NO Wi-Fi list ].

There is NO problem with Ethernet [ Wired ].

BOTH Problem 1, AND, Problem 2, work correctly if I perform a Restart because it Re-Establishes the Wi-Fi Connection.

I have tried MANY MANY different methods [ Looked at Log files, Event Logs, run PowerCFG Reports, etc, etc to name a few ] to resolve this, and if I were to list them ALL, this would make this post VERY VERY long indeed. Therefore I am happy to use workarounds until such time that I can address this again when I have more time.

Problem 1: [ Workaround ]

If the Wi-Fi DOES show in Control Panel > Network and Internet > Network Connections, then running the below Batch Script gets me back online . . .

Code:

@echo off
echo. & echo  Processing . . .
              netsh interface set interface "Wi-Fi" disable
              netsh interface set interface "Wi-Fi" enable & timeout /t 5 /nobreak >nul
echo  Current Network Adapter Status . . .
              netsh interface show interface
echo. & echo  Processing Complete.
echo. & echo ^>Press ANY key to EXIT . . . & pause >nul & Exit

It only takes a few seconds and I can live with that. The bonus is that the above does NOT require a Restart.

Problem 2:

If the Wi-Fi does NOT show in Control Panel > Network and Internet > Network Connections, I have to Restart the Laptop to Re-Establish the Wi-Fi Connection, hence trying to find a Workaround rather than keep Restarting the Laptop, which is OLD and takes a while.

WITHOUT Network Adapter ERROR

Wi-Fi MISSING

Wi-Fi Adapter - Power Management

Wi-Fi Class GUID


[ Collection of Data ]

In order to get ALL the Wi-Fi information that I need, I have run . . .

Code:

ipconfig /all
wmic nic get name, index
netsh interface show interface
powershell Get-NetAdapter ^| format-list
netsh wlan export profile key=clear folder="C:"
netsh wlan show profiles
netsh wlan show drivers
netsh wlan show wirelesscapabilities
netsh wlan show wlanreport

I also have the TWO Qualcomm Atheros AR9285 Wireless Network Adapter System Files that are found in the C:\Windows\System32\Drivers [ athwnx.sys & vwifibus.sys ] folder. I also have a netathrx.inf file in the C:\Windows\INF folder.

The above is just background information on PART of what I have performed SO FAR.

[ Workaround ]

MY QUESTION:

As I have Exported the Wi-Fi Profile [ When FULLY working ] as an .xml file . . .

> netsh wlan export profile key=clear folder="C:"

. . . would it be enough to use a Batch Script to Import the .xml file and have the Wi-Fi back ONLINE using . . .

> netsh wlan add profile filename="C:\XML_FileName.xml" user=all

If NOT, is there a way that this can be achieved please?

---

NOTE:

I REALLY want a Workaround for this rather than resetting SETTINGS or producing and posting pages and pages of logs or data.

EDIT:

I have been thinking about this.

In order to Add / Setup a Wi-Fi Network Offline [ Manually ] so to speak, which is what this Tutorial does . . .

> How to Add a Wireless Network Profile in Windows 10

. . . would . . .

> netsh wlan add profile filename="C:\XML_FileName.xml" user=all

. . . do EXACTLY the same thing?

I am waiting for this problem to reoccur so that I can test the above methods, but ANY input would be appreciated.

Thanks in advance,

Thanks for the reply @RickC, it is appreciated,

Have you tried whether DevCon's Restart will do the trick as a workaround? It looks like it can be used in a batch file to restart devices.

Info from Microsoft:
Windows Device Console (Devcon.exe)
DevCon Restart - parameters
Example: Restart a device

Other info:
Downloading DevCon for Windows 10

It will take some time to go through this so it is a job for tomorrow.

Hello @RickC,

Thanks for the reply.

That appears to require the download of the WDK which is quite big.

The problem I have is that the Wi-Fi disappears from the Network Connections page, so there is NO Device to Restart. That is why I am waiting for the problem to happen again and then use the .XML file to see if I can get it back Online.

@Paul Black,

I think you must enable "Allow computer to turn off this device" for sleep to work correctly.

I remember a laptop crashing completely while resuming because of that.

The specific Windows 10 version downloads appear to be ~6MB but you have to hunt them out rather than download the entire WDK... just MS being typically helpful MS.

First of all, many thanks for the links and information.

There is indeed a Batch Script that performs the renaming [ conversion process ] from the CAB to devcon.exe.

Unfortunately, the latest version that is available is v1809.

I had initially tried that setting BOTH On and Off as part of my diagnostics prior to posting this thread, but thanks for input.

UPDATE:

The problem occurred again this morning when I woke up the Laptop, the FIRST time in about 4 days. The Laptop is ALWAYS put to sleep & woken up several times a day.

I did notice that the Wi-Fi Tab was MISSING from Settings > Network & Internet > Wi-Fi [ I blanked out some of the Network info ] . . .



I tried running . . .

Code:

ipconfig /release
ipconfig /renew
arp -d *
nbtstat -R
nbtstat -RR
ipconfig /flushdns
ipconfig /registerdns

. . . but to NO avail.

I also ran FreeBooters ResetNetworkCompenents.bat file, but that required a Restart, which is NOT what I want. I am looking for LIVE solution that does NOT require a Restart.

I also tried Importing the Profile that I had previously Exported . . .

Code:

netsh wlan add profile filename="C:\XML_FileName.xml" user=all

. . . again to NO avail.

I also checked that the Network Drivers were NOT being removed from the System32 folder for some reason, and they were STILL there.

I have another couple of options that I can try the next time this occurs, which I will report.
