I have used this driver/setup utility on all of the windows operating systems except windows 3.1 because I no longer have that operating system.
Unzip into folder c:\NWG4. Have SOHO Router connected via straight through network cable, and then run file NWG4SETE.EXE. Once it finds the router, then click on settings and setup from there. This unit does not have a built in DHCP server, so you might have to setup your TCP/IP settings for your network card before running the setup file. Set your TCP/IP settings to IP address 192.168.0.2 with subnet 255.255.255.0 and your gateway to 192.168.0.1 and then you will be able to run the setup file and talk to and through the router and the modems attached to get to the internet. Good Luck and God Bless.
