Chapter 1
Introduction
This Chapter provides an overview of the Wireless Access Point's features and
capabilities.
Congratulations on the purchase of your new Wireless Access Point. The Wireless Access
Point links your Wireless Stations to your wired LAN. The Wireless stations and devices on the
wired LAN are then on the same network, and can communicate with each other without regard
for whether they are connected to the network via a Wireless or wired connection.
Figure 1: Wireless Access Point
The auto-sensing capability of the Wireless Access Point allows packet transmission up to
300Mbps for maximum throughput, or automatic speed reduction to lower speeds when the
environment does not permit maximum throughput.
Features of your Wireless Access Point
The Wireless Access Point incorporates many advanced features, carefully designed to provide
sophisticated functions while being easy to use.
•Standards Compliant. The Wireless Access Point complies with the IEEE802.11g and
IEEE802.11n draft 2.0 specifications for Wireless LANs.
•Supports 11n Wireless Stations. The 802.11n Draft standard provides for backward
compatibilitywith the 802.11b standard, so 802.11n, 802.11b and 802.11g Wireless sta-
tions can be used simultaneously.
•Speeds to 300Mbps. All speeds up to the 802.11n maximum of 300Mbps are supported.
•Bridge Mode Support. The Wireless Access Point can operate in Bridge Mode, con-
necting to another Access Point. Both PTP (Point to Point) and PTMP (Point to Multi-
Point) Bridge modes are supported.
And you can even use both Bridge Mode and Access Point Mode simultaneously!

•WPS Support. WPS (Wi-Fi Protected Setup) can simplify the process of connecting any
device to the wireless network by using the push button configuration (PBC) on the Wire-
less Access Point, or entering a 8-digit PIN code if there's no button.
•DHCP Client Support. Dynamic Host Configuration Protocol provides a dynamic IP
address to PCs and other devices upon request. The Wireless Access Point can act as a
DHCP Client, and obtain an IP address and related information from your existing DHPC
Server.
•Upgradeable Firmware. Firmware is stored in a flash memory and can be upgraded
easily, using only your Web Browser.
Security Features
•Virtual APs. For maximum flexibility, wireless security settings are stored in Virtual AP.
Up to 4 Virtual APs can be defined and used as any time.
•Multiple BSSIDs.Because each Virtual AP has it own SSID and beacon, and up to 4
Virtual APs can be active simultaneously, multiple SSIDs are supported. Different clients
can connect to the Wireless Access Point using different SSIDs, with different security set-
tings.
•Virtual APs Isolation.If desired, PCs and devices connecting to different Virtual APs
can be isolated from each other.
•VLAN Support. The 802.1Q VLAN standard is supported, allowing traffic from differ-
ent sources to be segmented. Combined with the multiple SSID feature, this provides a
powerful tool to control access to your LAN.
•WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit
128 Bit, and 152 Bit keys are supported.
•WPA support. Support for WPA is included. WPA is more secure than WEP, and should
be used if possible. Both TKIP and AES encryption methods are supported.
•802.1x Support. Support for 802.1x mode is included, providing for the industrial-
strength wireless security of 802.1x authentication and authorization.
•Radius Client Support. The Wireless Access Point can login to your existing Radius
Server (as a Radius client).
•Radius MAC Authentication. You can centralize the checking of Wireless Station
MAC addresses by using a Radius Server.
•Rogue AP Detection.The Wireless Access Point can detect unauthorized (Rouge)
Access Points on your LAN.
•Access Control. The Access Control feature can check the MAC address of Wireless
clients to ensure that only trusted Wireless Stations can use the Wireless Access Point to
gain access to your LAN.
•Password - protected Configuration. Optional password protection is provided to
prevent unauthorized users from modifying the configuration data and settings.
Advanced Features
•Command Line Interface. If desired, the command line interface (CLI) can be used for
configuration. This provides the possibility of creating scripts to perform common configu-
ration changes.
•Radius Accounting Support. If you have a Radius Server, you can use it to provide
accounting data on Wireless clients.
•Syslog Support. If you have a Syslog Server, the Wireless Access Point can send its log
data to your Syslog Server.

Introduction
3
•SNMP Support. SNMP (Simple Network Management Protocol) is supported, allowing
you to use a SNMP program to manage the Wireless Access Point.
•WDS Support. Support for WDS (Wireless Distribution System) allows the Wireless
Access Point to act as a Wireless Bridge. Both Point-to-Point and Multi-Point Bridge
modes are supported.

following browsers:
•Netscape V4.08 or later
•Internet Explorer V4 or later
Setup Procedure
Before commencing, install the Wireless Access Point in your LAN, as described previously.
1. Check the Wireless Access Point to determine its Default Name. This is shown on a label
on the base or rear, and is in the following format:
SCxxxxxx
Where xxxxxx is a set of 6 Hex characters ( 0 ~ 9, and A ~ F ).
2. Use a PC which is already connected to your LAN, either by a wired connection or another
Access Point.
•Until the Wireless Access Point is configured, establishing a Wireless connection to it
may be not possible.
•If your LAN contains a Router or Routers, ensure the PC used for configuration is on
the same LAN segment as the Wireless Access Point.
3. Start your Web browser.
4. In the Address box, enter "HTTP://" and the IP Address of the 11N Wireless Access Point,
as in this example, which uses the Wireless Access Point's default IP Address:
H T T P : / / 1 9 2 . 1 6 8 . 0 . 2 2 8
5. You should then see a login prompt, which will ask for a User Name and Password.
Enter admin for the User Name, and password for the Password.
These are the default values. The password can and should be changed. Always enter the
current user name and password, as set on the Admin Login screen.

If you can't connect:
It is likely that your PC’s IP address is incompatible with the Wireless Access
Point’s IP address. This can happen if your LAN does not have a DHCP Server.
The default IP address of the Wireless Access Point is 192.168.0.228, with a
Network Mask of 255.255.255.0.
If your PC’s IP address is not compatible with this, you must change your PC’s IP
address to an unused value in the range 192.168.0.1 ~ 192.168.0.254, with a Net-
work Mask of 255.255.255.0. See Appendix C - Windows TCP/IP for details for
this procedure.
