Will my Xbox work with the Gateway?
Yes, the Gateway is compatible with the Xbox. You need to set a static
IP
on the
Xbox in the Xbox live network settings, and forward ports 3074 (both
UDP
and
TCP
), 53 (both
UDP
and
TCP
), and 88 (
UDP
) if you run into DSL resolution
errors.
Is the Gateway flash-upgradeable? How do I do it?
Yes, the firmware is upgradeable. You can find a link to the firmware site under
“Utilities” in the Web-based configurator.
Does the Gateway function as a DSL modem?
Yes, the Gateway has a built-in
DSL
Modem.
Wireless
Can I use an 802.11b wireless card to connect to the Gateway?
Yes, the Gateway can handle 802.11b cards or 802.11g cards.
The 802.11g stan-
dard is backward compatible with the 802.11b standard. The Gateway can be
setup to handle just “g” wireless cards, just “b” wireless cards, or both.
If I install several Gateways in different locations in my building, will they
be able to talk to each other? Will I be able to stay connected as I move
between them?
The Gateway does not communicate with other access points, since it functions
as a single access point system. If you installed several Gateway devices and were
to move between coverage areas, your wireless device would have to reconnect to
a separate network.
Which wireless cards will work with the Gateway?
The Gateway connects with any wireless card supporting the 802.11g/802.11b
wireless standards.

Troubleshooting
Can my wireless signal pass through floors, walls, and glass?
The physical environment surrounding the Gateway can have a varying effect on
signal strength and quality. Generally, the more dense the object (a concrete wall
compared to a plaster wall, for example), the greater the interference. Concrete
or metal-reinforced structures will experience 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 standards. If you be use
the
WEP
security feature, refer to the Apple Airport documentation for infor-
mation 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. Reconfigure your network setting (Workgroup, Domain, Password, User
name,
IP
addressing or 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 192.168.1.64 to 192.168.1.254 by default.
How do I find out what IP address my computer is using?
Windows 95, 98, 98SE, and Me -
Select
Start
,
Run
, and type “winipcfg.” Press
Enter
.
When the “Winipcfg” window appears, ensure your network device is selected.

I used DHCP to configure my network. Do I need to restart my computer to
refresh my IP address?
No. Follow these steps to refresh your IP address:
Windows 95, 98, 98SE, and Me -
Select
Start
,
Run
, type “winipcfg,” and press
Enter
. Ensure the Ethernet adapter is selected in the device box. Press the
Release_all
button, then press the
Renew_all
button.
Windows NT 4.0 and 2000 -
Select
Start
,
Run
, type “cmd,” and press
Enter
. At the
DOS prompt, type “ipconfig /release,” then type “ipconfig /renew.”
Windows XP -
Unplug the Ethernet cable or wireless card and plug it back in.
Can I run an application located on another computer over the network?
Yes, if the application is designed to run over a network.
Can I play games between computers on my network, or on the Internet?
Yes, if the games were designed for multi-player or
LAN
play. For specific infor-
mation about whether a game is capable of Internet or
LAN
play, refer to the
game documentation. Some games require ports to be forwarded to host or join
games over the Internet.
I have an FTP or Web server on my network. How can I make it available to
users on the Internet?
For a Web server, enable port forwarding for port 8088 to the
IP
address of the
server and set up the Web server to receive on that port, as well. (Configuring
the server to use a static
IP
address is recommended.)
For an
FTP
server, enable port forwarding for port 21 to the
IP
address of the
server. (Configuring the server to use a static
IP
address is recommended.)
Connections
How many computers can be connected through the
Gateway?
The Gateway is capable of 254 connections, but it is recommended to have no
more than 45 connections. As you increase the number of connections, you
decrease the available speed for each computer.

Troubleshooting
Security
What is the default username for the Gateway?
The default username for the router is “admin” and the default password is
“password” (all lower case, no quotation marks). To activate the password to
protect the Gateway, change the default password. Remote management will not
be available on the Gateway until the default password is changed.
Does the Gateway function as a firewall?
Yes. The Gateway provides its security through the use of
NAT
firewall, which
acts as a physical barrier between your network and the Internet.
What is NAT and how does it protect my network?
NAT
(Network Address Translation) is a type of security that masks the private
IP
addresses of the computers on your network with a single public
IP
address.
With
NAT
, the private
IP
address of the computers on your network is never
transmitted over the Internet.
Which Virtual Private Networking (VPN) protocols are supported?
The Gateway supports pass-through for
PPTP
,
L2TP
, and
IPS
ec.
