I’ve seen an odd factor that my model new Lenovo laptop computer loses Internet connection over a Wi-Fi adapter after waking up from sleep or hibernation. In this case the wi-fi connection standing says “No Internet entry” or “”. On some cause after waking up from sleep or hibernation the Wi-Fi adapter can not mechanically reconnect to my residence Wi-Fi entry level, and the listing of wi-fi networks is empty. If the laptop computer is restarted, Windows will mechanically connect with my Wi-Fi community and I can entry the Internet directly as traditional. The subject is kind of irritating and tiresome, since I have to restart the laptop computer a number of occasions a day (enabling/disabling Wi-Fi adapter in the Device Manager has not helped).
In this text I’ll present you the way I’ve coped with the issue of dropping Wi-Fi connection in Windows 10 after waking up from sleep mode.
Update the Wi-Fi Adapter Drivers
Prior to transferring to the subsequent methodology, attempt to obtain and set up the latest model to your Wi-Fi adapter drivers from the distributors’s web site. If the issue with the disconnection out of your Wi-Fi community had appeared immediately, Windows might have mechanically up to date the driving force of your Wi-Fi adapter lately. So, you must attempt to use an older model of the driving force that remained in the native driver repository in your pc (see this rollback ).
If you might have discovered an appropriate driver and the Wi-Fi connection will not be misplaced with it, it is suggested to for this machine.
Disable Power Saving Mode for Wireless Adapter
Windows 10 makes use of energy saving mode for many . Windows can mechanically flip off completely different units in order to avoid wasting your laptop computer battery. It is kind of rational and efficient method to lengthen the battery lifetime of your machine. However, some community adapter fashions can not resume right operation after waking up from the sleep mode with out pc reboot. It might happen on account of an incorrect machine structure, firmware or drivers. In this case it is suggested to disable energy saving mode to your Wi-Fi community adapter. To do it:
- Open the Device Manager (
- Expand the Network Adapters part and discover your Wi-Fi adapter (often it has Wireless or 802.11 in its identify), then open its properties;
- Go to the Power Management tab and uncheck the choice Allow the pc to show off this machine to avoid wasting energy. Save the modifications by clicking OK.
If you might have a number of community adapters in your pc/laptop computer, together with an Ethernet LAN adapters (for instance, Realtek PCIE Controller), you could disable energy saving mode in their properties as properly.
It can also be beneficial to alter energy saving choices. To do it, go to the Control Panel -> Power Options -> Change plan settings -> Change superior energy settings -> Wireless adapter settings -> Power saving mode -> choose Maximum efficiency.
Restart WLAN AutoConfig Service
In my case all strategies mentioned above didn’t assist. As it turned out, the issue was associated to the WLAN AutoConfig service.
WLAN AutoConfig service is used in Windows 10 to handle all wi-fi connections (Wi-Fi and Bluetooth). It is WlanSvc that’s liable for detecting, connecting to and disconnecting from wi-fi networks and . If you cease the service, Windows received’t have the ability to see wi-fi networks and to hook up with them.
After waking up from Sleep, open the listing of providers in your pc (
providers.msc) and discover “WLAN AutoConfig” in the listing. Make certain that it’s configured to begin mechanically. Try to restart it. In my case, I couldn’t do it. When attempting to restart/begin the service, the next message appeared in the console:
Windows couldn’t begin the WLAN AutoConfig service on Local Computer.
WlanSvc began efficiently solely after the restart of the pc. I discovered that svchost.exe of WlanSvc hangs on after hibernation. It is
C:windowssystem32svchost.exe -k LocalSystemNetworkRestricted –p (you’ll be able to see this path in the service properties).
Try to kill the method in the Task Manager (Ctrl+Shift+Esc). To do it, discover Service Host: Local Service -> WLAN AutoConfig in the Processes tab, choose Details in the context menu and finish the method by clicking End Task. After that you could begin the WlanSvc service in the service administration console.
I wrote a easy PowerShell script to be run with the administrator privileges after Windows had waken up from hibernation or sleep mode to restart WLAN AutoConfig service:
$WLANProc = Get-CimInstance Win32_Process | Where-Object
Stop-Process -Id $WLANProc.ProcessId -Force
You may additionally have to restart your Wi-Fi adapter:
restart-netadapter -InterfaceDescription 'your_wireless_adapter_name' -Confirm:$false
It is the latter methodology that has helped me to repair the problem of dropping Wi-Fi community connection after wakeup from sleep in Windows 10.
