b.
To allow access from a range of IP addresses on the Internet, select IP address range.
Enter a beginning and ending IP address to define the allowed range.
c.
To allow access from a single IP address on the Internet, select Only this computer.
Enter the IP address that will be allowed access.
3.
Specify the Port Number that will be used for accessing the management interface.
Web browser access normally uses the standard HTTP service port 80. For greater security,
you can change the remote management Web interface to a custom port by entering that
number in the box provided. Choose a number between 1024 and 65535, but do not use the
number of any common service port. The default is 8080, which is a common alternate for
HTTP.
4.
Click Apply to have your changes take effect.
Note:
When accessing your router from the Internet, you will type your router's WAN IP address
into your browser's Address (in IE) or Location (in Netscape) box, followed by a colon (:) and the
custom port number. For example, if your external address is 134.177.0.123 and you use port
number 8080, you must enter in your browser: http://134.177.0.123:8080
Using Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers, access
the network and connect to other devices as needed. UPnP devices can automatically discover the
services from other registered UPnP devices on the network.

Turn UPnP On:
UPnP can be enabled or disabled for automatic device configuration. The default
setting for UPnP is enabled. If disabled, the router will not allow any device to automatically
control the resources, such as port forwarding (mapping), of the router.
Advertisement Period
: The Advertisement Period is how often the router will broadcast its UPnP
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes.
Shorter durations will ensure that control points have current device status at the expense of
additional network traffic. Longer durations may compromise the freshness of the device status but
can significantly reduce network traffic.
Advertisement Time To Live
: The time to live for the advertisement is measured in hops (steps)
for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is
allowed to propagate for each UPnP advertisement before it disappears. The number of hops can
range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should
be fine for most home networks. If you notice that some devices are not being updated or reached
correctly, then it may be necessary to increase this value a little.
UPnP Portmap Table
: The UPnP Portmap Table displays the IP address of each UPnP device that
is currently accessing the router and which ports (Internal and External) that device has opened.
The UPnP Portmap Table also displays what type of port is opened and if that port is still active for
each IP address.
Advanced Wireless Settings
Note
: Incorrectly changing these settings can prevent the wireless functions from working.

These settings normally do not need to be changed.
WMM support
WMM (Wireless Multimedia) is a subset of the 802.11e standard. WMM allows wireless
traffic to have a range of priorities, depending on the kind of data. Time-dependent
information, like video or audio, will have a higher priority than normal traffic. For WMM to
function correctly, wireless clients must also support WMM. The default is Disable.
RTS Threshold
Request to Send Threshold. The packet size that is used to determine if it should use the
CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism or the
CSMA/CA define the mechanism for packet transmission. With the CSMA/CD transmission
mechanism, the transmitting station sends out the actual packet as soon as it has waited for the
silence period. With the CSMA/CA transmission mechanism, the transmitting station sends
out an RTS packet to the receiving station, and waits for the receiving station to send back a
CTS (Clear to Send) packet before sending the actual packet data.
Fragmentation Length
This is the maximum packet size used for fragmentation. Packets larger than the size
programmed in this field will be fragmented. The Fragment Threshold value must be larger
than the RTS Threshold value.
Beacon Interval
Specifies the data beacon rate between 20 and 1000.
DTIM
The Delivery Traffic Indication Message. Specifies the data beacon rate between 1 and 255.
Preamble Type
A long transmit preamble may provide a more reliable connection or slightly longer range. A
short transmit preamble gives better performance.

Troubleshooting
This chapter gives information about troubleshooting your ProSafe Wireless 802.11g
Firewall/
Print Server Model FWG114P v2. After each problem description, instructions are provided to
help you diagnose and solve the problem.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1.
When power is first applied, verify that the PWR LED is on.
2.
After approximately 10 seconds, verify that:
a.
The TEST LED is not lit.
b.
The LAN port LEDs are lit for any local ports that are connected.
If a port’s LED is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’s LED is green. If the port is 10
Mbps, the LED will be OFF.
c.
The Internet port LED is lit.
If any of these conditions does not occur, refer to the appropriate following section.
Power LED Not On
If the Power and other LEDs are off when your router is turned on:
Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
Check that you are using the 12 V DC power adapter supplied by NETGEAR for this product.
If the error persists, you have a hardware problem and should contact technical support.
