Lenovo G70-70 Wireless Problem

I have a Lenovo G70-70 laptop with Windows 7 64 bit Operating System. It is a new installation of Windows 7. The problem I am having is I cannot get the wireless adapter drivers installed. I went to the Lenovo site and allowed their software to detect my laptop and downloaded the suggested driver. It was actually several drivers bundled in one package. When I tried to install after the download I got an error message that said, "No Appropriate driver will be installed."
I then went to the folder where the drivers are stored and tried each individually, (there was an Intel driver, Broadcomm, Atheros) and each appeared to install but none allowed the adapter to function.
I then checked the wireless adapter and searched for the model #. It is QCNFA34AC which is a Qualcomm Atheros QCNFA344A (QCA6174A) adapter. I went to their website and downloaded the recommended driver but when I installed it the adapter was not found.
The adapter/network controller is listed in Device manager. If I right click on it and select update driver no driver and be found.

Please help.

Thank you!

In Device Manager, look under Network and then the Wireless Adapter. Is it "working normally" or is there a yellow or red exclamation mark?

The is very likely a Wi-Fi switch on the case of the laptop (there is on my T61p and X250). Make sure that switch is ON.

Are there multiple drivers installed (look in Programs and Features) ?  Uninstall all Wireless drivers, shut down, start up and try again.

Is there a recovery partition for you to do a factory reset on the laptop?  If you do that then it should install all appropriate drivers during the install.

There are not multiple drivers installed and the properties page shows no driver installed (Code 28).

Is this the HD that came with the laptop or is it a replacement?

What about the WiFi physical switch?

Also go to Lenovo / Support and under downloads, search for your model (G70) and look for an Atheros driver.

what was the reason for the fresh install ?
if it was the wi-fi that did not work - it may possibly be bad - then you need another wifi card
you can test if it works by running from a live Knoppix cd :

The reason for the fresh install was that this laptop is a refurb that came with Windows 8. I did not want Windows 8 so I installed Windows 7.

And this is the driver package you tried?

http://support.lenovo.com/us/en/products/laptops-and-netbooks/lenovo-g-series-laptops/g70-70-laptop/downloads/DS101266

Did the wireless work when Windows 8 was installed on it?

ok -  and the wi-fi was working then?
if not ..it may have been bad from start
luckily you can replace the wi-fi card easily in most

Yes, ScottCha - that was the driver package I tried.

I did not try the wireless with Windows 8 because I have no interest in that O/S at all.

What you might want to do is pull the wireless card and look at it.  It's possible it may have been replaced with another card and none of the drivers you are trying will work.

See if you can get any information from that and find an appropriate driver.

Also, what does properties in Device Manager tell you about the device?  There should be an identification string for it.

ScottCha - if you read my initial question I mentioned that I did exactly what you suggested - "I then checked the wireless adapter and searched for the model #. It is QCNFA34AC which is a Qualcomm Atheros QCNFA344A (QCA6174A) adapter. I went to their website and downloaded the recommended driver but when I installed it the adapter was not found. "

you can test if it works with another OS - ubuntu or such
or try running from a live Knoppix cd

So something is wrong with the Windows installation. Did you use the Lenovo Recovery DVD or did you use Retail Windows.

If the latter, make sure you have upgraded ALL of:  BIOS, Chipset, Video, Hotkey, Audio, UltraNav, Bluetooth, and Power Manager driver.

I used a retail version so I will make sure everything is up to date.

did you try the Knoppix cd?  if it does not run there, it is likely hardware faulty.

does it show the new wifi adaptor ?  in error or ok?
