My Netgear Wireless-N 300 USB Adapter WNA3100 isn't able to complete installation because when it tells me to connect the usb adapter to my computer, the computer auto installs the softwear and the install isn't able to complete. what can i do?

Your device is not suppoted by Win7.
NETGEAR Support Answer NETGEAR Product compatibility for Microsoft Windows...

It may not be compatible with Windows Vista Home Premium.

It looks like your NetGear WNA3100 is dead out of the box.
The software looks like it operating correctly (runs the installed diag, tries to detect, etc.), but
the software isn't having any luck finding the hardware.
The reason that the adapter is disabled in Device Management, is that the software seems
to have correctly installed the driver, but Windows couldn't detect (plug & play) the device, so
Windows didn't enable the device driver - Windows won't load a driver for a non-existent device.
Other (remote) possibilities:
(a) Wi-Fi adapter plugged into a bad USB port. - try another port.
(b) there's a little corrosion on USB contacts of USB port or WNA3100. Try plugging adapter
in and out of the port a few times (this shines up the contacts a bit).
(c) there's a slight misalignment of contacts within the USB connector or either the laptop, or
the WNA3100.
Your fix may be returning the NetGear WNA3100 to the retailer for an exchange.

first download the latest driver if it dont work check it on other system if it works then check ur port and ifit also dont works call ur customercare

try to download different driver for your adapter.

Hi,
I Would guess, that windows is leaving the handeling of the wireless connection to the NETGEAR software, and therefor not registering the device ad connected.
To make Windows regain controle take a look at this: http://www.bukisa.com/articles/115878_how-to-let-windows-configure-your-wireless-network-connection-in-xp

Netgear does not have Windows 2000 drivers for this product. They are only showing drivers for Windows XP, Vista, and 7.

Hi!
Sure you can! Download it from here...
