I wasn't aware that Atheros ever made a networking device called "ntx86.6.0". Atheros doesn't actually build networks cards, they make networking chips (and none match the "ntx86.6.0" number you posted.
You'll get a faster and more accurate answer if you provide the following information with your request:
(this info should accompany every request on this board but less than .10% actually do so)
1: Did this device come pre-installed in your computer at the time of purchase or did you purchase it later then add it to the computer?
2: Are you sure about the interface being PCI? Other types include: "PCI-E" add-on cards, or "notebook mini-cards", or "external USB/PCMCIA", and "integrated on the motherboard" are valid interfaces. If your device interface is not listed, then select "Other" then use the comment box to provide the type of interface. Actually, those that do post the interface post an incorrect interface. I just answered a request prior to yours where the member claimed his network device had a IDE interface (not).
3: Is this device a LAN (wired) or WLAN (wireless) device?
4: Is this device used in a Desktop or Laptop computer?
5: Computer/motherboard brand and model?
6: Did the computer come from the factory with Windows 7 installed?
If you're unable to provide answers to the above questions, then I suggest using this hardware identification/driver finding software:
To find make and model of pc hardware, EVEREST Home Edition
is a free system diagnostics, system information program that will id most hardware onboard a mb. as well as the actual motherboard. It will, in some cases, actually provide a download link for the driver.
Alternate Everest download link: (offers 2 sites to dl program from)
Run the program and then:
Click on Computer
Click on Summary
Right hand window (hardware) if the text is BLUE
this is a link to the web site for that particular hardware.
If you have additional questions or need further help, please post a "copy and paste" of the COMPUTER SUMMARY report (Leave out the Debug–PCI section) from Everest.
And atheros ntx.86.6.0
doesn't make a good choice for a member name. It will be confusing if you need a driver for a different device.
