Wireless Connection Not Responding After Hibernation

My Windows 7 computer was originally setup for manual connection to a network. A couple months ago, without setting it otherwise, it started connecting automatically to our network. Now, I don't have a problem with that and I can set it to manual again if I want, but I just thought I would mention it in case it has something to do with my problem...

Here's the real problem: About a week ago we set a password on our wireless network (to keep neighbors off). That's when the problems started, but I can't imagine they have anything to do with what's happening. When I initially start my computer, it connects to the internet no problem. But when I put it in hibernation or sleep mode, then return to it later, my browsers tell me that I am not connected. When I try to click on the wireless icon on my taskbar, it doesn't respond. It does absolutely nothing. When I go into Control Panel and view Network and Internet, then click on "Connect to a Network", it still does not respond. In the end, I have to restart the whole system to get on the internet.

What's going on here, and how do I fix it??

Thanks!

I might try deleting and then recreating the profile and see if that fixes it.

And welcome to the forum!

Thanks for the welcome!

I tried as you suggested, and for a while I thought it worked... but just now I got back on my computer after putting it in hibernation mode and once again it wouldn't automatically connect. This time the icon on the taskbar responds, but it says that it's currently connecting to our wireless network, even though nothing happens even after five minutes of "connecting". When I click "Disconnect", the "Disconnect" button won't respond. I ended up having to restart my computer again. I tried disabling my computer's wifi, but still nothing happened.

...Could this have something to do with the new password we set?

The password should be entered into the computer when you established the "new" connection that you previously got rid of.

Well, I entered the password and was able to access the internet. But it's still not letting me on after I wake my computer up. It just won't connect, and won't let me see any connection options.

Let's check to see if any of your protected system files have become corrupt:

Left click the Windows flag in the lower left corner of the screen. Type cmd, right click on cmd.exe and select Run as Administrator. You might have to click on Yes if the UAC security window pops up. In the command prompt window that appears type sfc /scannow and press enter.

You may have to run it up to three times if errors are found/corrected.

It would appear that the Network connection goes to deep sleep on hibernation and so doesn't connect as it doesn't wake up. Try the following.

01. Go to Control Panel\Network and Internet\Network Connections.
02. Click on Change Adapter Settings.
03. Right Click LAN and then click on Properties.
04. Press Configure Button and then the Power Management Tab.
05. Uncheck Allow the Computer to turn of this Device to save Power.

That is it. Now the Network Adapter would not fall into deep sleep again and your problem should get resolved.

Thanks for your replies!

Sibbil: I did just as you said (a couple of times till it finally told me the results). It says "Windows Resource Protection did not find any integrity violations."

Anak: Thanks for the welcome! I finally filled in most of my specs (hopefully I filled it in correctly), so thanks for posting that link. I had no idea what they were and wasn't quite sure how to figure that out. Here's what you asked for (I think I did it right.....)

Wanchoo: I took the steps you suggested... the "Turn off this device" option was checked, so I unchecked it. Hopefully that's it! :)
