We all use WiFi on our Windows 10/8 computers to access the Internet. But many times, we run into different kind of issues about the 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 loses the WiFi network connectivity.
In this scenario, after resuming from sleep, Windows would show that WiFi connections are available, but it doesn’t automatically reconnect, or it doesn’t stay 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:
Internet or 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.
2. In the Device Manager window, expand Network Adapters and look for your WiFi driver, do a right-click on it, select Properties.
3. In the property sheet, switch to Power Management tab and uncheck the option. Allow the computer to turn off this device to save power. Click OK.
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
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!
