Wifi connection inactive
« on: August 06, 2013, 08:47:33 PM »
Hello the forum,
I posted this thread in the French part of this forum but receive no answer. This is why I post it in the English part.
A few days ago, I played the sorcerer's apprentice in running multiple programs to clean my Win 7 registry.
As consequence, my WIFI connection is becoming inactive.

In the Device Manager, the Network Adapters entry shows:

Avast! Firewall NDIS Filter Miniport (with an orange triangle and a!)

Whose properties display an error message:
Windows cannot start this hardware device Because its configuration information (in the registry) is incomplete or damaged. (Code 19).
I uninstalled Avast free with aswClear and then reinstall them but the wifi connection remains inactive
Should a member of the forum could advise me to repair my silliness.

Thanks in advance for your answers.

Tom

Right click the Avast! Firewall NDIS Filter Miniport  and select delete
Then run a repair on Avast

Hi Essexboy,

Thanks for your quick answer.
There is no "delete" function with the right click on "Avast! Firewall NDIS Filter Miniport" in the Device Manager. I guess you mean "uninstall"
Would you please clarify what you mean by " run a repair on Avast".
Regards
Tom

Sure I did mean uninstall  :-[

To repair Avast go to Control Panel > Programs and Features
Select Avast and on the left will be a repair option
Select that

Is the network working ?

Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:
  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices
  • List Users, Partitions and Memory size.
  • List Minidump Files

Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.
 
Note: When using "Reset FF Proxy Settings" option Firefox should be closed.

Hi essexboy,
Thanks for your answer.
I ran MiniToolBox.
The result is attached.
The hope that it might help to solve the problem.
The number of errors detected is it disturbing?
Regards,
Tom

Hi essexboy,
I have no error message.
Simply (!) the switch on the front the computer remains inactive while two weeks ago, the wifi connection was working properly.
Meantime I ran several programs to clean the win7 register. Since then, my wireless connection is disabled.
The sole network adapter with a problem was the Avast! Firewall NDIS Filter Miniport (with an orange triangle and a!) (see first post).
But I don't know if there is a relation.
All ideas or suggestions to solve the problem are welcome.
Regards,
Tom

Hi,
First link: drivers downloaded and installed .
Second link: more disturbing. For Wifi, it says: No Integrated wireless device and the "turn wireless on" button is inactive; the Centrino network adapter is still working properly.
Do you have any other suggestions or would it better that I go to the HP support?
In any case, many thanks for your advices, they reflect your skill.
Regards
Tom

Hi,
I'm a little ashamed but I found the solution.

As I hesitate to use "hardware" manipulations that I can not understand, I "Googled" in every way and I fell a little by chance:
http://h30434.www3.hp.com/t5/Wireless-Internet-Home-Networking-e-g-Windows-8/Wireless-disabled-by-wireless-button-message-Resolved/td-p/618821
So I uninstalled the HP Wireless Assistant, restart the pc and my wireless connection is anew operational.
In any case, thank you for answering me.
Tom
