1. Introduction
Congratulations on your purchase of this Super G™ Wireless Access Point. The Access
Point features four operating modes. The Access Point mode connects your wireless
clients with the wired part of your network. The AP client mode acts as a wireless
network adapter for your PC or game console. The AP Repeater mode extends the
range of your access point/wireless router by repeating the signal to wireless clients that
are beyond the broadcasting range of the access point/wireless router. This provides
the wireless clients with greater flexibility and mobility. Finally, the Point to Point Bridge
mode bridges the network clients from two physically separate LANS into one virtual
LAN.
The Access Point is compatible with existing 802.11b and 802.11g network devices so it
will work with most existing wireless devices. If you have other Super G™ compatible
wireless network device, you can also enable Super G™ on the Access Point for faster
transfer rate.*
Instructions for installing and configuring this product can be found in this manual.
Before you install and use this product, please read this manual carefully for proper

If you want to use the AP421W as an Access Point with minimal configuration, just
connect it to your existing router or switch with a Cat. 5 network cable and then power it
on. The Access Point is ready to use with its default settings:
SSID: default
Channel: 6
Encryptions: disabled
If you want to configure the Access Point’s settings or set it to other operating modes,
please follow the rest of this guide.
Step 1 Connect one end of a network cable to the Network port of the Access Point
and connect the other end to one of the LAN ports of the router (See the diagram
below).
Step 2 Power on the Access Point by connecting one end of the supplied power
adapter to the power jack of the Access Point and connecting the other end to an
electrical outlet.
Step 3 Verify that all three lights on the Access Point are lit. If not, verify that all the
connections are secure and try again.

Step 1 On the wired computer, go to Start, Run, type command (for Windows
95/98/ME) or cmd (for Windows 2000/XP) and click OK.
Step 2 Type ipconfig and press Enter. Your network settings will be displayed.
Step 3 Write down the values for the IP Address, Subnet Mask, and Default Gateway
on a piece of paper.

down the following values for your existing wireless router or AP:
1. SSID (Network Name)
2. Channel Number
3. Wireless Security Settings
The AP421W needs to use the same wireless settings in order for it to work properly.
You may gather these information from the web configuration utility of your wireless
router.
Step 5 Refer to the IP Address you’ve written down from Step 3.

Configuration Utility.
If the first three numbers of your IP Address are not 192.168.1, (Ex. 192.168.2), then
