Chapter 4 
Advanced Configuration
This chapter describes how to configure the advanced features of your NETGEAR WG102 
ProSafe 802.11g Wireless Access Point. These features can be found under the Advanced heading 
in the main menu.
The following features are explained: 
• Hotspot Settings: Redirect HTTP requests.
• Advanced Wireless Settings: Set up advanced wireless LAN parameters.
• Access Point Settings: Enable wireless bridging and repeating.
Hotspot Settings
If you want the access point to capture and redirect all HTTP (TCP, port 80) requests, use this 
feature. For example, a hotel might want all wireless connections to go to its server to start a 
billing transaction.
Enter the URL of the Web server where you wish to redirect HTTP requests.

v1.0, July 2008
Configuring Advanced Wireless Settings
You can use the Advanced Wireless Settings screen to configure the advanced wireless settings. If 
you want the AP to operate in Super-G mode, use this feature.
The advanced wireless settings normally do not need to be changed. 
•Super-G Mode. Super-G Mode is a proprietary extension to the 802.11g standard, which can 
double the throughput to 108Mbps. Only compatible wireless stations can use this mode. The 
default is Disable.
•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, have a higher priority than normal traffic. For 
WMM to work 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 Carrier Sense Multiple Access with Collision Detection mechanism (CSMA/
CD) or the CSMA/CA mechanism for packet transmission. With CSMA/CD, the transmitting 
station sends the packet as soon as it has waited for the silence period. With CSMA/CA, the 
transmitting station sends out an RTS packet to the receiving station, and waits for the 
receiving station to send back a Clear to Send (CTS) packet before sending the packet data. 
The default is 2346.
•Fragmentation Length. This is the maximum packet size used for fragmentation. Packets 
larger than this size will be fragmented. The Fragment Threshold value must be larger than the 
RTS Threshold value. The default is 2346.
•Beacon Interval. The interval time (between 20ms and 1000ms) for each beacon 
transmission. The default is 100.
Figure 4-3

Advanced Configuration 4-3
v1.0, July 2008
•DTIM Interval. The Delivery Traffic Indication Message (DTIM) specifies the data beacon 
rate between 1 and 255. The default is 1.
•Preamble Type. A long transmit preamble may provide a more reliable connection or slightly 
longer range. A short transmit preamble gives better performance. Auto automatically handles 
both long and short preambles. The default is Auto.
Wireless Bridging and Repeating
The WG102 Access Point lets you build large bridged wireless networks. Examples of wireless 
bridged configurations are:
•Point-to-Point Bridge. The WG102 Access Point communicates with another bridge-mode 
wireless station. See 
“Point-to-Point Bridge Configuration” on page 4-4.
•Multi-Point Bridge. The WG102 Access Point is the “master” for a group of bridge-mode 
wireless stations. Then all traffic is sent to this “master,” rather than to other access points. See 
“Multi-Point Bridge Configuration” on page 4-5.
•Repeater with Wireless Client Association. Sends all traffic to the remote AP. See “Repeater 
with Wireless Client Association” on page 4-7.
These configurations can be set up from the Advanced Access Point Settings screen, shown below.

v1.0, July 2008
Point-to-Point Bridge Configuration
In Point-to-Point Bridge mode, the WG102 Access Point communicates with another bridge-mode 
wireless station. In addition, you can enable client associations with this WG102 Access Point. 
You must enter the MAC address of the other bridge-mode wireless station in the field provided. 
Use WEP to protect this communication. The figure below shows an example of Point-to-Point 
Bridge mode.
Follow the steps below to set up a Point-to-Point Bridge configuration.
1.Configure the WG102 Access Point (AP1) on LAN Segment 1 in Point-to-Point Bridge mode.
2.Configure the other access point (AP2) on LAN Segment 2 in Point-to-Point Bridge mode. 
AP 1 must have AP 2’s MAC address in its Remote MAC Address field and AP 2 must have 
AP 1’s MAC address in its Remote MAC Address field.
3.Configure and verify the following for both access points:
• Verify the LAN network configuration of the access points. Both must be configured to 
operate in the same LAN network address range as the LAN devices
• Both APs must use the same ESSID, Channel, authentication mode, if any, and security 
settings if security is in use.
4.Verify connectivity across the LAN 1 and LAN 2.

A computer on either LAN segment should be able to connect to the Internet or share files and 
printers of any other PCs or servers connected to LAN Segment 1 or LAN Segment 2.
Multi-Point Bridge Configuration
Set up a Multi-Point Bridge only if this WG102 Access Point is the “master” for a group of bridge-
mode wireless stations. Then all traffic is sent to this “master,” rather than to the other access 
points. In addition, you can enable client associations with this WG102 Access Point. 
• You must enter the MAC addresses of the other access points in the fields provided. 
• The other bridge-mode wireless stations must be set to Point-to-Point Bridge mode, using the 
MAC address of this WG102 Access Point as the Remote MAC Address. 
• Use WEP to protect this traffic. 
The figure below shows an example of a Multi-Point Bridge mode configuration.
Follow the steps below to set up the Multi-Point Bridge configuration.
1.Configure the Operating Mode of the WG102 Access Points.
• Because it is in the central location, configure WG102 Access Point (AP 1) on LAN 
Segment 1 in Point-to-Multi-Point Bridge mode. The MAC addresses of AP2 and AP3 are 
required in AP1.

• Configure WG102 Access Point (AP 2) on LAN Segment 2 in Point-to-Point Bridge mode 
with the Remote MAC Address of AP1.
• Configure the WG102 Access Point (AP3) on LAN 3 in Point-to-Point Bridge mode with 
the Remote MAC Address of AP1.
2.Verify the following for all access points:
• The LAN network configuration of the WG102 Access Points are configured to operate in 
the same LAN network address range as the LAN devices
• Only one AP is configured in Point-to-Multi-Point Bridge mode, and all the others are in 
Point-to-Point Bridge mode.
• All APs must be on the same LAN. That is, all the APs LAN IP address must be in the 
same network.
• If using DHCP, all WG102 Access Points should be set to “Obtain an IP address 
automatically (DHCP Client)” in the IP Address Source portion of the Basic IP Settings 
menu.
• All WG102 Access Points use the same SSID, Channel, authentication mode, if any, and 
encryption in use.
• All Point-to-Point APs must have AP2’s MAC address in its Remote AP MAC address 
field.
3.Verify connectivity across the LANs. 
• A computer on any LAN segment should be able to connect to the Internet or share files 
and printers with any other PCs or servers connected to any of the three LAN segments.
• Wireless stations will not be able to connect to the WG102 Access Points in the 
illustration above. If you require wireless stations to access any LAN segment, you can 
use additional WG102 Access Points configured in Wireless Access Point mode to any 
LAN segment.
Note: You can extend this multi-point bridging by adding additional WG102 Access 
Points configured in Point-to-Point mode for each additional LAN segment. 
Furthermore, you can extend the range of the wireless network with NETGEAR 
wireless antenna accessories.

Repeater with Wireless Client Association
In this mode, the WG102 Access Point sends all traffic to the remote AP. For repeater mode, you 
must enter the MAC address of the remote “parent” access point. You can also enter the address of 
the “child” access point. Note that the following restrictions apply:
•You do not have the option of disabling client associations with this WG102. 
• You cannot configure a sequence of parent/child APs. You are limited to only one parent/child 
AP pair. 
The figure below shows an example of a Repeater Mode configuration.
To set up a repeater with wireless client association, follow the steps below:
1.Configure the Operating Mode of the WG102 Access Points.
• Configure AP 1 on LAN Segment 1 as the Parent in Repeater mode with the its own MAC 
address in the Parent AP MAC Address field, and the MAC Address of the ‘downstream’ 
AP (AP 2) in the Child AP MAC Address field.
• Configure AP 2 in the Child Repeater mode with its MAC addresses as in the Child AP 
MAC Address field and the MAC address of the ‘upstream’ AP (AP 1) in the Parent MAC 
Address field.
2.Verify the following for all access points:

• The LAN network configuration of the WG102 Access Points are configured to operate in 
the same LAN network address range as the LAN devices
• All APs must be on the same LAN. That is, all the APs LAN IP address must be in the 
same network.
• If using DHCP, all WG102 Access Points should be set to “Obtain an IP address 
automatically (DHCP Client)” in the IP Address Source portion of the Basic IP Settings 
menu.
• All WG102 Access Points use the same SSID, Channel, authentication mode, if any, and 
encryption in use.
3.Verify connectivity across the LANs. 
A computer on any LAN segment should be able to connect to the Internet or share files and 
printers with any other PCs or servers connected to any of the three WLAN segments.
Note: You can extend this repeating by adding up to two more WG102 Access Points 
configured in repeater mode. However, since repeaters communicate in half-duplex 
mode, the bandwidth decreases as you add repeaters to the network. Also, you can 
extend the range of the wireless network with NETGEAR wireless antenna 
accessories.
