You have now completed the hardware installation of your Gateway. Next you
need to set up your computers so that they can make use of the Gateway to
communicate with the Internet.
3Com recommends that you perform the initial Gateway configuration from a
computer that is directly connected to one of the LAN ports. You may alternatively
configure the Gateway from a wireless computer, but note that you may lose
contact with the Gateway if you change the wireless configuration.
To communicate with the Gateway, your wireless NIC should be set as follows:
