The physical environment around the Gateway can have a varying effect on wireless signal strength and
quality. The more dense an object, the greater the interference. Concrete or metal reinforced structures
will cause a higher degree of signal loss than those made of wood, plaster, or glass.
I have an Apple computer that uses the Airport wireless device. Is this device compatible with
the Gateway?
Yes, the Apple Airport system complies with the 802.11b and 802.11g standards. If you use the WEP
security feature, refer to the Apple Airport documentation for information on the proper method to enter
the WEP key for compatibility with the Gateway’s hexadecimal WEP entry.
Network
I use my laptop at work and at home. Is there something special I need to do to make it work in
both places?
Yes. You must reconfigure your network settings, including Workgroup, Domain, Password, User name,
IP addressing, and any other specific settings used by your company. You may also use third-party
software like NetSwitcher to automatically switch between different configurations.
What is the valid IP range I can use for my home network?
The valid IP range for the Gateway is 192.168.0.2 to 192.168.0.254 by default.
How do I find out which IP address my computer is using?
Windows 98, 98SE, and Me - Select Start, Run, and type winipcfg. Press Enter. When the
“Winipcfg” window appears, ensure your network device is selected.
Windows NT, 2000, and XP - Select Start, Run and type cmd. Press Enter. When the command
screen is displayed, type ipconfig and press Enter.
