Windows 10: Wi-Fi gets disconnected after sleep

I get a new laptop Vostro 5490 with Win10 Pro 2004. everything works great but once my laptop goes into sleep mode it's become a problem. I can go in and out of sleep mode just fine, but my problem is that upon exiting sleep mode my computer cannot pick up any wifi signals and the computer must be reset.

Wi-Fi disconnect

Windows doesn't disconnect a properly working WiFi. Mine NEVER disconnects since the last time I restarted my computer. I suggest to check for near-by WiFi radios to see if your channel is too crowded or if all the channels are crowded, just switch to 5 GHz band like mine

 

Wi-Fi disconnects from internet after resuming from Sleep Mode

That seems to involve a restart.

There are quicker ways.

All that is needed is to disable the network adapter (ethernet or WiFi), and then re-enable it!
Lets do it manually:
*Start+R (Run shortcut) and type ncpa.cpl and press <enter> to bring up the Network Connections control panel:





Select either the WiFi adapter (this is commonly the adapter that gets confused), or Ethernet if that is problematic. From the toolbar that appears, select Disable this network device and the device is disabled:





Now select Enable this network device and the device is enabled and it should automatically connect within a few seconds. Sometimes it is necessary to select Connect to and select the WiFi network you want:





No restart required. See here for an even simpler way with a batch file:

Is there a simple script to reset the wi-fi adapter

 

Wi-Fi Disconnects After Sleep or Switches to Airplane Mode - Troubleshooting Fails

Thanks Abdul,

I tried your suggestions. The Network Adapter troubleshooter couldn't identify any problem and I have the most up-to-date Network Adapter driver. I cleared the Allow the computer to turn off this device to save power check box, and then clicked
OK.

When I brought the laptop out of sleep a few times it was ok but most recently it was disconnected from Wi-Fi so I had to click Wi-Fi and select the connection to my Wi-Fi which was never necessary prior to Windows 10.
