I usually use the internet in 3 locations on my laptop and till a few days back the laptop would connect fine to all 3 wifi networks. However, out of the blue my laptop stopped connecting to the wifi at location A and B, and still connects fine at location C. Other laptops and phones still connect fine to the wifi at location A and B, there's been no change in the software on my laptop since before the problem and I've run a system restore too to back when it was working, with no luck. I've uninstalled and reinstalled the adapter driver, also cleared my saved network locations and tried to connect again. Any other suggestions?

Hey mdpais,
Have you deleted the remembered wifi networks from the Network and sharing center ?

  • In the Run box that appears, type CMD and click on OK.
  • Type the following command:
    • IPCONFIG /ALL
  • Right click in the command window and choose Select All, then hit Enter.
  • Paste the results in a message here.

How does wireless network C differ from A and B (channel, encryption, mode)?

Make sure you have the latest wireless driver--from the PC manufacturer's web site if integrated, else from the adapter manufacturer's web site.

Yes, I did. Now it shows up in the available wifi connections and when I click on connect it starts the process and asks me for my password, once I enter it I get the error "Windows was unable to connect to ABC" where ABC is the name of the wifi connection. I've checked the passwords on the other machines that are able to connect to the connection and it's correct.

You need this while I'm trying to connect to the wifi right? Please confirm. Right now I'm using an internet stick/dongle to connect to the net since I'm unable to connect to the wifi.

Just a note. I'm not able to connect to the router itself, let along the internet.

How does wireless network C differ from A and B (channel, encryption, mode)?
<br />
<br />
Same network provider, same encryption, same router manufacturer, different router models. In fact location A and C have the same router models.

Make sure you have the latest wireless driver--from the PC manufacturer's web site if integrated, else from the adapter manufacturer's web site.
<br />
<br />
I do. Checked it. Even installed it and downloaded again from the manufacturer's website and reinstalled it again.

For locations A and B try to connect with encryption disabled on the router. If successful you can probably re-enable encryption and reconnect.

I would like to avoid changing anything on the router unless absolutely necessary as the rest of my family connects to the same wifi with no problems at present. My phone too connects to all 3 locations with no problem. My laptop used to as well, until a few days back. Do you really think it's an issue with the router?

I really think that there is a strong possibility that this is one of those cases where the encryption between router and adapter "got out of sync." If so, that dance will fix it. If not, no damage done. Yes, anybody wanting to use the Wi-Fi during those few minutes while the encryption is disabled will be inconvenienced.

Another thing you can try, before or after the above, is a System Restore to a point before the problems started.

Yes, I would like to see the report while you are experiencing the problem.

Also, what do you mean you're suing an "Internet stick"? Assuming you mean a USB Network Adapter, this is the device that is unable to see the wireless network, right?

I am presently at location C right now. Will try it out tonight.

One of the first things I tried. No luck there.

I mean one of those mobile internet dongles that can be used through the USB port. Connects through a SIM card in it.

This section of the IPConfig log tells us about your network adapter (what detects wireless signals).

If you notice at the top it says "Media State...Media disconnected". The reasons for this are numerous, but the end result is the same -- your network adapter will not work.

Please do the following in order.

-------------------------------------------------------

Enable Wireless Network Adapter
  • Press and hold the Windows key + R on your keyboard.
  • In the Run box type Control and hit Enter.
  • In the Control Panel click the drop-down menu and select Large Icons.
  • Select Network and Sharing Center.
  • In the Network and Sharing Center window, click Change adapter settings.
  • Locate your wireless network adapter and right-click it.
  • Click Enable.
-------------------------------------------------------

IP Release and Renew
  • Press and hold the Windows button + R on your keyboard. A Run box should appear.
  • Type CMD into the Run box and press Enter.
  • In the command prompt, type ipconfig /release and press Enter.
  • Once the prompt returns, type ipconfig /renew and hit Enter.
  • Finally, type exit and press Enter to close the window.
-------------------------------------------------------

TCP/IP Stack Repair - Vista, Windows 7, Windows 8
  • Press and hold the Windows key + R and hit Enter.
  • In the Run box, type cmd and hit Enter.
  • In the Command Prompt, type each of the following commands followed by Enter:
    • netsh winsock reset catalog
    • netsh int ipv4 reset reset.log
    • netsh int ipv6 reset reset.log
  • Reboot the machine.

TheShooter93: Well a little after I posted the ipconfig data on this thread, my laptop started connecting to the wifi at location A (in fact location A happens to be the first place where the problem started). No idea how, I'd given up trying anything and had planned on just waiting for a reply from the forum when suddenly it seems to have fixed itself. Now to test the laptop at location B and ensure it's working there as well. If there's a problem I'll go through the steps you've given. Thanks for all the help :)

Ok, the problem started again as easily as it solved itself. So I've followed your instructions and here's what's happened:

Enable Wireless Network Adapter
  • Press and hold the Windows key + R on your keyboard.
  • In the Run box type Control and hit Enter.
  • In the Control Panel click the drop-down menu and select Large Icons.
  • Select Network and Sharing Center.
  • In the Network and Sharing Center window, click Change adapter settings.
  • Locate your wireless network adapter and right-click it.
  • Click Enable.
Was already enabled.

IP Release and Renew
  • Press and hold the Windows button + R on your keyboard. A Run box should appear.
  • Type CMD into the Run box and press Enter.
  • In the command prompt, type ipconfig /release and press Enter.
  • Once the prompt returns, type ipconfig /renew and hit Enter.
  • Finally, type exit and press Enter to close the window.
Received the reply "No operation can be performed on Wireless Network Connection while it has its media disconnected" for both the above commands.

TCP/IP Stack Repair - Vista, Windows 7, Windows 8
  • Press and hold the Windows key + R and hit Enter.
  • In the Run box, type cmd and hit Enter.
  • In the Command Prompt, type each of the following commands followed by Enter:
    • netsh winsock reset catalog
    • netsh int ipv4 reset reset.log
    • netsh int ipv6 reset reset.log
  • Reboot the machine.
First command was successfully carried out.
Second command was successfully carried out.
There's no user specified settings to be reset.

Just a clarification here. Through all this (from before the problem till now) my adapter is enabled and is detecting available connections with no problem. The available wifi connections shows up for all locations (A, B and C). Before, since all the locations were saved on my laptop, whenever I was in range of any of the locations it would automatically connected to it. Now that I've deleted them from the remembered connections I need to manually tried to connect to location A and B. When I click on the connect button, I get the pop-up asking me to enter the Network Security Key and after I enter it I get the error "Windows was unable to connect to ABC" when trying to connect to ABC wifi". This is not a problem with the password as I've tried entering the wrong password and when I do so, I get the error saying that the network security key is wrong. So I figure that the laptop is communicating fine with the router to vieify the password but is not getting through beyond that.

As I was typing the above I tried connecting again and its suddenly connected to location A. This is seriously a mind boggling problem.
