Never. Just never.

Never has, never will

Aug and it took forever! Haha

As an IT specialist, I can confirm this.

Actually, it has worked on my Mum's laptop at least twice. No clue what was wrong, just that it fixed whatever it was and that the same effect would probably have come from turning either the wifi or the laptop itself off and on again.

It's works to reset the WiFi card if it has been disabled and won't turn back on. My laptop started disabling it's WiFi card randomly and that was the only way to fix it.

It often works for me

It is much quicker to disable and enable the wifi or use ipconfig.

It works occasionally but it usually never works

Like 1-100 times it works
