Fix: WiFi gets disconnected after Sleep in Windows 8 / 10

We all use WiFi on our Windows computers to access the Internet. But many a times, we run into different kind of issues pertaining to usage of WiFi. We have already seen how to fix poor WiFi performance, limited WiFi networks, WLAN AutoConfig service not starting, etc. Today, we are sharing with you, the way to fix the issue of WiFi getting disconnected after you resume from Sleep mode. If you’re connected to a WiFi network and you move your system into sleep mode, after waking up, the  system loose the WiFi network connectivity.

WiFi-Gets-Disconnected-After-Sleep

In this scenario, after resuming from sleep, Windows 8 would show that WiFi connections are available but it doesn’t automatically reconnect or it doesn’t stays connected during sleep. This would affect your user experience, if you rely upon background processes running on your system like to downloading using Windows Store or Download Manager, etc.  So if you’re getting frustrated with this problem, you can try these steps referenced from  this wiki article:

WiFi gets disconnected or does not automatically reconnect

Using Device Manager

1. Press Windows Key + R and type devmgmt.msc in the Run dialog box to open Device Manager.

You may now close Device Manager and restart the machine to get your issue fixed.

Using Windows PowerShell

1. Go to Desktop, right click and select New -> Shortcut. In the Create Shortcut window paste this command:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe restart-netadapter -InterfaceDescription '<WIRELESS ADAPTER NAME HERE>' -Confirm:$false

Substitute your system root drive with C: and wireless adapter name which you can get from Device Manager window shown previously in this article. In our case the wireless network adapter was Intel(R) Pro/Wireless 3945ABG Network Connection, so the command becomes:

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe restart-netadapter -InterfaceDescription 'Intel(R) Pro/Wireless 3945ABG Network Connection' -Confirm:$false

Click Next.

2. Moving on, name this shortcut like WiFi Reset and click Finish.

3. Finally, right click the shortcut so created and select Properties. Click Advanced and in the Advanced Properties window, check option Run as administrator. Click OK, then Apply followed by OK.

You can pin this shortcut to Start Screen and double click as soon as you came around the issue. After double clicking, let the system execute the command and reboot the machine. This should fix the problem.

Hope this helps!

    i tried this and it didn’t work. Then I rolled back the driver in device manager and that worked. the latest driver is corrupted.

    Nice, thanks for help

    Amazing, thanks for this. I’ve been looking for a way to script a restart of the wifi adapter for ages but couldn’t find any info on how to do it.

    Of course, it would be nice if Windows could successfully power the wifi adapter back on after sleep…

    Why does it work after I restart my computer, but once the computer goes into sleep mode again I get no Internet access on my adapter bar and all my Internet programs stop working?

    Worked perfectly on my new pc that is running Windows 10. Thanks

    Mine has done it twice now. The first time I fixed it by disabling everything and then re-enabling everything then restarting. The second time that tactic didn’t work. The icon that shows up is saying no connections are available. Both times this occurred when coming out of sleep mode.

    I have an ASUS Netbook and am encountering this problem. However, there is no Power Management option to disable under the Broadcom 80.11abgn Wireless SDIO Adapter…any ideas on how I could fix this…I couldn’t even reconnect o the WIFI after the computer goes to sleep w/o restarting

    thank you! I used the device manager steps and it worked; am surprised that the default is to cut off your wifi

    I use a Thinkpad Yoga and not sure I could get this to work. Whenever I take my personal computer to work, when I boot it up, I have to login to the guest network. Anytime I close the lid on my laptop though, when I open it back, I have to relogin into the guest network. I tried unchecking the Allow the computer to turn off this device to save power to my Intel (R) Dual Band Wireless AC 7260 #2, but it still has this problem.
