Figure 7 Installing without a splitter
You have now completed the hardware installation of your Router. Next
you need to set up your computers so that they can make use of the
Router to communicate with the Internet.
3Com recommends that you perform the initial Router configuration
from a computer that is directly connected to one of the LAN ports.
If you configure the Router from a wireless computer, note that you may
lose contact with the Router if you change the wireless configuration.
To communicate wirelessly with your Router, your wireless NIC should be
set as follows:
Encryption — none
Service Area Name/SSID — 3Com
Channel — 11
