Netgear models wnda4100 need drivers

NO!

what problem?

You can download the software from

http://support.netgear.com/product/wnda4100

Go to Netgear's support site here http://support.netgear.com/app/home/session/L3NpZC9wWTFnQzN5aw%3D%3D

You'll need to know the letter that follows the wg111 to pick your model then you should be able to find the driver for your operating system and download it.

Hmm..
try a new driver perhaps?

it must be configured to a router not a modem

Yes, the adapter would only work with its compatible software driver. Which can be downloaded from the below link:

Please enter the model make of the adapter on the box and it will take you to the download page.

hi,
you can download the drivers from here:
http://kb.netgear.com/app/answers/detail/a_id/2721/session/L2F2LzEvc2lkL0RnNEptM1Rq

the drivers should be installed in windows 7 by default, their so called "smart wizard" has some compatibility issues with windows 7, I get it to load up and it will shut down or glitch out. What I did was uninstall the downloaded driver and use the default windows drivers, flipped the switch off to my built in G wifi adapter and the netgear automatically kicked in and took over as the default wireless adapter.

To isolate the issue. please install the adapter on another computer. If the other computer does not detect the adapter then that means the adapter is faulty.

Let me know the results.
