[FONT=&quot]Dear tech experts, I have an issue with ASUS N56VZ notebook with Windows 7 Home Premium - my WLAN stopped working. A bit of history leading to the malfunction: wifi reception quality was weak in my apartment and I had tried to improve it by using ASUS USB-N66 and USB-N53. Both devices refused to work with this laptop, I got a couple of BSOD instances and then my internal Atheros 9485 stopped working completely. I changed multiple driver versions without any success. I didn't bother to create recovery points, which I now understand was a big mistake. I also read about on the web how bad this particular Atheros's reputation is and decided that it may have malfunctinoned and the Intel adapter may work better. So I installed N6230 but got exactly same results. Both device are OK in the Device Manager, visible via "netsh wlan show all" as "Not ready" and not visible via "ipconfig /all". I fought and removed some tunnel adapters as per various forum threads and also did some deactivations to ipv6, not sure how it all looks now. I list below results for:
- TSG Sysinfo
- ipconfig /all
- netsh wlan show all
Hope for your assistance - thanks in advance! (never mind the cyrillic letters in connection descriptions - these are generic words saying "network connection etc")

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG , Webroot etc

lets see the following please

xirrus screen shot

------------------------------------------------------------------------
Run Xirrus Wi-Fi Inspector
Download and install

If you cannot access the internet with this PC, then you will need to copy the program across to the faulty PC
Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and install the program.
You will now need to take a screen shot and copy that back to the working PC and attach the screen shot in a reply on the forum here.

http://www.xirrus.com/Products/Wi-Fi-Inspector.aspx
Direct link to the program is here http://info.xirrus.com/Wi-FiInspectorConfirmation.html

{If the above link does not work heres another link http://www.pcworld.com/downloads/file_download/fid,77196-order,4/download.html}

Then run and install the program - on a wireless enabled PC/Laptop
if you get an error - You need will need to have NET Framework installed for the WiFi Inspector to function.
On windows 8 - (i do not have windows 8) but, it would appear that, When you first try to run, you may get a message that .net framework is needed, and included in that message is a link to download/install.

Run the program

A user guide is available here http://www.xirrus.com/cdn/pdf/Xirrus-Wi-Fi-inspectorguide-1-2-1-RevB-6.aspx

post a screen shot of the program running.
if there are a lot of networks showing can you click on "networks" top lefthand area - so we can see all the network information.

post which SSID name is yours, its located in the list, under network "Adapter Name" (1st column)

To post a screen shot of the active window.
1) (For windows 8 see below) hold the Alt key and press the PrtScn key. Open the Windows PAINT application (Start> All Programs> Accessories> Paint) and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
OR
2) if you are using Vista/Windows 7 you can use the "snipping tool" which is found in Start> All programs> Accessories> Snipping Tool

To upload the screen shot to the forum, open the full reply window ("Go Advanced" button) and use the Manage Attachments button to upload it here.
Full details are available here http://library.techguy.org/wiki/TSG_Posting_a_Screenshot


Note:
For a reliable (or robust as the Xirrus user guide says) wireless connection you need a signal of about -70 dBm or better. "A desirable signal level for a robust Wi-Fi connection will be green".
note: the signal level is a negative number, so for example -88 is worst and -40 is better

If you are using the Mac OS then use http://www.istumbler.net/

if you want to optimise base station position and signal strength / dead spots use
http://www.chimoosoft.com/products/apgrapher/ which has a graph function to monitor signal

For windows 8 - I dont have windows 8 and not tried - but this should work

1) MSPaint is only available in classic desktop mode and can not use this program with the new Windows 8 start screen.
You can find MSPaint by typing &#8220;mspaint&#8221;, which will search and allow you to install.
MS "Fresh Paint program" is for Windows 8, download free from the Windows 8 store.

2)
>Open Snipping Tool (From the Windows 8 Start Screen, type "snip" and press enter.
>Press the Esc. key.
>go back to your Windows 8 start screen - Swipe from left or press Window Button
>Press Ctrl+PrntScr button to use Snipping Tool

Antivirus - Avast free version.
Firewall - ZoneAlarm free version.
Xirrus screenshot attached - no surprises, there are no networks as the adapter is not working.

Xirrus at least sees the adapter
so in the past when the adapter does not appear in ipconfig /all the majority of cases often involves a windows re-install
BUT a few things in the past have resolved the issue on a few PCs

1) Remove zone alarm
2) Chkdsk
3) SFC /scannow

so lets try those
--------------------------------------------------------------
Zonealarm Removal Tool
The latest versions have the uninstalled included in the installation
run the ZA uninstaller from Start > Programs > ZoneAlarm

removal tool
http://download.zonealarm.com/bin/free/support/download/clean.exe
You need to use Internet Explorer as other browsers corrupt the download

windows 7
https://support.zonealarm.com/index...arm-from-windows-vista-64-and-windows-7-64bit

If possible, first try to run the universal uninstaller found at the link below. This tool will remove all ZoneAlarm data from your computer: When the download box pops up, choose Save, in the next box choose Save to Desktop. Restart the computer before running the tool.

Thank you so much! I uninstalled the friggin' ZoneAlarm and everything is back to normal! Marking this as solved. I can't believe a firewall would cause so many problems.

yep, you will see removing firewalls here , norton, mcafee etc etc - usually resolves issues and probably average 1 a day here or higher
