Chapter 1. Introduction
Thank you for choosing the Zcomax (UK) Limited’s AG-3621 Access Point (hereafter called
access point). This Access Point provides a secure, affordable, and easy-to-use wireless LAN
solution that combines mobility and flexibility with the enterprise-class features required by
networking professionals.
This chapter gives an overview of the enterprises-class AG-3621 access point, as well as its
key features. In addition, we detail about the hardware description, system requirement and
basic installation.
Overview
802.11a/b/g-compliant, this access point distinguishes herself by one built-in mini-PCI card,
providing wired and wireless two ports in a bigger infrastructure. Typically, VAP functionality
allows a single network AP to behave as “8” number of virtual network APs. This does away
with the limitation by the sheer number of Ethernet connections that need APs acting as a
proxy. WMM prioritizes traffic demands from different applications and extends Wi-Fi’s high
quality end-user experience from data connectivity to voice, music, and video applications
under a wide variety of environment.
This Access points serves as the connection point between wireless and wired networks or as
the center point of a stand-alone wireless network. In large installations, wireless users within
radio range of an access point can roam throughout a facility while maintaining seamless,
uninterrupted access to the network.
You can configure and monitor the access point using the command-line interface (CLI), the
browser-based management system, or Simple Network Management Protocol (SNMP).
This Access Point currently can support data rate up to 108Mbps. Users are encouraged to
update their latest firmware through http://www.zcom.com.tw
Networks are useful tools for sharing computer resources. You can access one printer from
different computers and access data located on another computer's hard drive. Networks are
even used for playing multiplayer video games. So, networks are not only useful in homes
and offices, they can also be fun. Use the instructions in this Guide to help you connect the
Access Point, set it up, and configure it to bridge your different networks. These instructions
should be all you need to get the most out of the Access point.

Chapter 2. Basic Installation and Securities
This chapter explains how to place and connect the AG-3621 Access Point. In addition, the
AG-3621’s security features are elaborated.
Note
You need to prepare these three things before you can establish a connection
through your wireless access point.
• A location for the AG-3621 that conforms to the Observing Placement and Range Guidelines
below.
• The wireless access point connected to your LAN through a device such as a hub, switch,
router, or Cable/DSL gateway.
• One or more computers with properly configured 802.11a/b/g.
Operating Distance Tips:
The range of your wireless connection is significantly determined by the physical placement
of the access point.
To optimize the results, place your wireless access point:
• Near the center of the area in which your PCs will operate.
• In an elevated location such as a high shelf where the wirelessly connected PCs have
line-of-sight access (even if through walls).
• Away from sources of interference, such as PCs, microwaves, and 2.4 GHz cordless phones.
• Away from large metal surfaces.
• Putting the antenna in a vertical position provides best side-to-side coverage. Putting the
antenna in a horizontal position provides best up-and-down coverage.
• If using multiple access points, it is better if adjacent access points use different radio
frequency Channels to reduce interference. The recommended Channel spacing between
adjacent access points is 5 Channels (for example, use Channels 1 and 6, or 6 and 11).

Getting To Know AG-3621 Wireless Security Options
Zcomax (UK) Limited wants to make wireless networking as safe and easy for you as possible.
The current generation of Zcomax (UK) Limited products provides several network security
features, but they require specific action on your part for implementation. So, keep the
following in mind whenever you are setting up or using your wireless network.
Security Precautions
The following is a complete list of security precautions to take as shown in this User’s Manual.
(at least steps 1 through 5 should be followed):
1. Change the default SSID.
2. Disable SSID Broadcast.
3. Change the default password for the Administrator account.
4. Enable MAC Address Filtering.
5. Change the SSID periodically.
6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that
this may reduce your network performance.
7. Change the WEP encryption keys periodically.
To ensure network security, steps one through four should be followed, at least. Wireless
networks are easy to find. Hackers know that in order to join a wireless network, wireless
networking products first listen for “beacon messages”. These messages can be easily
decrypted and contain much of the network’s information, such as the network’s SSID
(Service Set Identifier).
Security Options
There are several ways you can enhance the security of your wireless network:
• Restrict Access Based on MAC address. You can restrict access to only trusted clients so
that unknown clients cannot wirelessly connect to the AG-3621. MAC address filtering adds
an obstacle against unwanted access to your network, but the data broadcast over the
wireless link is fully exposed.
• Use WEP. Wired Equivalent Privacy (WEP) data encryption provides data security. WEP
Shared Key authentication and WEP data encryption will block all but the most determined
eavesdropper.
• Use WPA or WPA-PSK. Wi-Fi Protected Access (WPA) data encryption provides data
security. The very strong authentication along with dynamic per frame re-keying of WPA
makes it virtually impossible to compromise.

Firmware Version: Firmware is stored in a flash memory and can be upgraded easily, using
your Web browser, and can be upgraded via ftp server or ftp server. The currently available
version of AG-3621 is 1.1.3.0.
IP Type: By default, the AG-3621 is configured as static IP Address.
IP Address: The IP address must be unique to your network. The default IP address is
192.168.1.1
Note
To associate the access point to your PC, make sure the PC IP address
need to be matched the AP. For instance, the AG-3621 is 192.168.1.1, and
your PC IP should be 192.168.1. X.
Subnet Mask: The Subnet Mask must be the same as that set on the LAN that your Access
Point is connected to. The default is 255.255.255.0.
Operating Mode: AG-3621 provides five modes, Access Point, Station, bridge, repeater and
inter-building.
Access Point: Act as a standard 802.11a/b/g. The default mode is Access Point.
Station: Perform as a clie nt station associated to other APs. Be sure that they share the same
SSID when connected.
Bridge: The AG-3621 acts as a bridge connecting APs. Two bridge modes are available
below.
Point-to-Multi-Point Bridge:Select this only if this AG-3621 is the “Master” for a group of
bridges. The other bridge must use this AG-3621 MAC address. They then send all traffic to
this “Master”, rather than communicate directly with each other. WEP should be used to
protect this traffic.
Wireless Repeater: In this mode, the AG-3621 can communicate with another wireless station
or wireless bridge. You can enter the MAC address of both adjacent repeaters in the fields
provided to communicate with other wireless bridge or use SSID to communicate with other
wireless station. WEP should be used to protect this communication.
Wireless Mode: Select the desired wireless operating mode. The default mode is 802.11a.
Channel: This field identifies which operating frequency will be used.
Security Profiles: This provides a list of virtual APs derived from AG-3621 Virtual AP, spelling
