Netgear wireless N adapter HOW to connect to Windows 7

If you can't get your computer to recognize your wireless adapter, but it lights on adapter is up that mean your computer doesn't have proper driver installed!

USB uses 4 shielded wires: two for power (+5v & GND) and two for differential data signals (labelled as D+ and D- in pinout). That why your lights is on on USB device but it is not functioning.

Well good news, it is compatible!

Windows 7 Automatically Installs Some NETGEAR Adapters by using it own DLL's sources, but it could fail in some rare cases.

First of all identify what is your adapter model, you may need specific driver.

Look here for your driver details, enter in search box, download it, download  manuals, read instructions and install it properly.
