Windows 10 WiFi connection after sleep

Ever since I upgraded to Windows 10 from Windows 7, I've had WiFi issues. This only happens after the computer is woken up from sleeping.

It may already have the previous day's connection open, and if not I can connect to it or any other network. However it doesn't matter. Every connection says there's no Internet available. I might add that it's always a public WiFi and the accept terms screen never pops up. It also doesn't matter what the public network is.

My current workaround is to disable my network adaptor and immediately re-enable it. Then I connect to the WiFi without any issues. This is a workable solution, but it's getting old. Any ideas?

Here's my system:

  • OS: Windows 10 Professional 64-bit
  • Network adapter: Intel(R) Centrino(R) Advanced-N 6200 AGN
  • Drivers: Intel NETwsw00.sys (15.11.0.7) , vwifibus.sys (rs1_release.160715-1616)
  • System security: Kaspersky Total Security

My old laptop encountered similar problems following the upgrade from Windows 7 to Windows 10. I was able to alleviate the problem by disabling the Fast Startup option:

  1. Open the Control Panel in icons view.
  2. Select Power Options
  3. Select Choose what the power buttons do on the upper-left.
  4. Select Change settings that are currently unavailable link near the top (if prompted by UAC, select Yes).
  5. Under Shutdown settings, uncheck the box to Turn on fast startup
  6. Click on the Save Changes button.
  7. Close the System Settings window and reboot.
