I am trying to install a WUSB54G Adapter on a Windows 98SE machine. I downloaded the latest firmware from the linksys website for the USB adapter. During the install I get a NDINST illegal operation. I can click close on the message box and error goes away and I can continue with installation, but once the software is installed the USB adapter can connect to the Router, but it does not get a IP address. I am assuming the NDINST illegal operation is part of the problem. I even tried with security disabled and it still would not get an IP address.
