Why do I keep losing Wi-Fi after sleeping? - fixedByVonnie

Why do I keep losing Wi-Fi after sleeping?

Instead of writing a discursive post about why Wi-Fi shouldn’t sleep when the PC sleeps I’ll get right to the point:

Does your network connection feel rife with problems?  Have you ever noticed that your network connection abruptly quits when your PC sleeps?

When you wiggle the mouse or stroke the touchpad it obediently wakes but then you have to explicitly click  the Wi-Fi icon to reconnect.

So what should you do?

  • Disable sleep mode all together?
  • Change your power saving mode to Maximum Performance
  • Google around for hours until you find an answer in some obscure message board?

Nope.

Here’s the thing:

If Allow the computer to turn off this device to save power has been disabled for the Intel Wireless LAN device then the computer does something really inane: it functions like its on.

In other words, if you don’t allow the computer to turn off the adapter then the computer turns it off anyway.  So to get around the problem we need to make sure Allow the computer to turn off the device to save power is enabled.

Here’s how to pull off this trick off…

Click the Windows icon in the bottom left corner of the screen and type:

device manager

In the Device Manager, expand the Network Adapters device and then right click your Wi-Fi adapter and choose Properties.

Windows 8.1 Device Manager

Zip over to the Power Management tab and make sure Allow the computer to turn off this device to save power has a check in the box.

Allow the computer to turn off the device to save power

Click OK and that’s it.

I don’t know why this happens (Microsoft has a knowledge base article on the issue) but my gut tells me there’s a bug in the Intel software where the driver expects the value to be TRUE; however if it’s FALSE, meaning it’s empty, the software just does a NOT Boolean operation against the expected TRUE value which results in the wrong value: FALSE.

That’s pure speculation, as I have nothing to support that but it’s my best conjecture right now.

Anyway, if this helped you please share the love in the comments!
