Wireless LAN Networking

The following figure provides an example of a wireless network with an AP.

The wireless network is the part in the blue circle. In this wireless network, devices A and B are called
wireless client. The wireless clients use the access point (AP) to interact with other devices (such as
the printer) or with Internet. Every wireless network must follow those basic guidelines.

1. Every device in the same wireless network must use the same SSID. The SSID is the name of the
wireless network. It stands for Service Set Identity.

2. If two wireless network overlap, they should use a different channel. Like radio stations or
television channels, each wireless network uses a specific channel, or frequency, to send and
receive information.

3. Every device in the same wireless network must use security compatible with the AP or peer
computer.

Introduction

The SMCWEB-N is a multi-function Wireless-N (802.11n draft) networking device: Access
Point and Ethernet Client modes. Designed for multimedia applications SMCWEB-N can be
used in Access Point mode to add high-speed wireless connectivity to your network, or Client
mode to simultaneously connect multiple Ethernet enabled devices such as a game console,
digital media player or Network Attached Storage.

The SMCWEB-N is 802.11n draft v2.0 compliant while maintaining full backwards
compatibility with the Wireless-G (802.11g) and Wireless-B (802.11b) standards. This next
generation wireless networking standard utilizes advanced MIMO (Multiple-In, Multiple-Out)
technology to deliver incredible speed and range. With wireless speeds up to 300Mbps and
extended coverage, there is enough bandwidth to simultaneously stream video and audio,
play online games, transfer large files, make VoIP calls and surf the Internet. With security
being a key consideration, SMCWEB-N supports the latest WPA and WPA2 wireless
encryption standards, which prevent unauthorized access to wireless networks and ensure
data is secure. Wireless security can also be set up easily using Wi-Fi Protected Setup
(WPS) that enables push button or PIN configuration.

For an enhanced multimedia experience Wireless Intelligent Stream Handling technology
automatically manages and prioritizes the flow of time-sensitive data in your wireless network,
without the need for end user configuration. As a result time-sensitive applications like online
gaming, voice and video, run smoothly without lag and breakup problems. Finally,
configuration is made simple and straightforward with the Installation Wizard, intuitive
web-based management interface and slide switch for easily selecting operating mode.

Installation Considerations

The SMCWEB-N lets you access your network, using a wireless connection, from virtually anywhere within
its operating range. Keep in mind, however, that the number, thickness and location of walls, ceilings, or
other objects that the wireless signals must pass through, may limit the range. Typical ranges vary
depending on the types of materials and background RF (radio frequency) noise in your home or business.
The key to maximizing wireless range is to follow these basic guidelines:

1 Keep the number of walls and ceilings between the SMCWEB-N and other network devices to a

minimum - each wall or ceiling can reduce your wireless product’s range from 3-90 feet (1-30
meters.) Position your devices so that the number of walls or ceilings is minimized.

2 Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a

45-degree angle appears to be almost 3 feet (1 meter) thick. At a 2-degree angle it looks over 42
feet (14 meters) thick! Position devices so that the signal will travel straight through a wall or ceiling
(instead of at an angle) for better reception.

3 Building Materials can impede the wireless signal - a solid metal door or aluminum studs may have

a negative effect on range. Try to position wireless devices and computers with wireless adapters
so that the signal passes through drywall or open doorways and not other materials.

4 Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that

generate extreme RF noise.

Getting Started

For a typical wireless setup please do the following:

1. Select desired operation mode using the slide switch on the back panel. AP mode
configures the SMCWEB-N to function as a wireless access point. Client mode
configures the SMCWEB-N to function as an Ethernet to wireless bridge. Client mode
is used for connecting Ethernet devices such as a game console, digital media player

or Network Attached Storage. You can directly connect up to 4 devices. Note: The

default mode is AP.

2. Using the yellow RJ-45 cable connect port LAN1 on the SMCWEB-N to your network

or Ethernet client device(s). Now connect the power supply. Ethernet LAN ports of the
SMCWEB-N are Auto MDI/MDIX and will work with both Straight-through and
Cross-Over cable.

3. To access the default management IP address your PC must have an IP address in
the range 192.168.2.3~254, with subnet mask 255.255.255.0.

4. Start web browser and enter address http://192.168.2.2 (default). When prompted

enter password smcadmin then click [Log In]. Note: The User Name must be set to

Admin.

5. Click [Wireless Network Setup Wizard] and follow the on screen instructions to
complete the set-up and reboot.

7

Using the Configuration Menu in AP Mode

Whenever you want to configure your SMCWEB-N, you can access the Configuration Menu through your
PC by opening the Web-browser and typing in the IP Address of the SMCWEB-N. The SMCWEB-N’s
default IP Address is http://192.168.2.2.

¾ Open the Web browser.

¾ Type in the IP Address of the SMCWEB-N (http://192.168.2. 2).

¾ Select Admin in the User Name field.

¾ Enter Password: smcadmin (default).

¾ Click Login In.

Basic

The Basic tab provides the following configuration options: Wireless Settings and Network Settings.

Basic_ Wireless Settings

The wireless section is used to configure the wireless settings for your access point. Note that changes
made in this section may also need to be duplicated on wireless clients that you want to connect to your
wireless network.

To protect your privacy, use the wireless security mode to configure the wireless security features. This
device supports three wireless security modes including: WEP, WPA-Personal, and WPA-Enterprise. WEP
is the original wireless encryption standard. WPA provides a higher level of security. WPA-Personal does
not require an authentication server. The WPA-Enterprise option does require a RADIUS authentication
server.

9

Enable Wireless

This option turns off and on the wireless connection feature of the access point. When you set this option, the
following parameters are in effect.

Wireless Network Name

When you are browsing for available wireless networks, this is the name that will appear in the list (unless
Visibility Status is set to invisible, see below). This name is also referred to as the SSID. For security purposes,
it is highly recommended to change from the pre-configured network name.

Enable Auto Channel Scan

If you select this option, the access point automatically finds the channel with least interference and uses that
channel for wireless networking. If you disable this option, the access point uses the channel that you specify

with the following Wireless Channel option.

Wireless Channel

A wireless network uses specific channels in the wireless spectrum to handle communication between clients.
Some channels in your area may have interference from other electronic devices. Choose the clearest
channel to help optimize the performance and coverage of your wireless network.

802.11 Mode

If all of the wireless devices you want to connect with this access point can connect in the same transmission
mode, you can improve performance slightly by choosing the appropriate "Only" mode. If you have some
devices that use a different transmission mode, choose the appropriate "Mixed" mode.

Channel Width

The "Auto 20/40 MHz" option is usually best. The other options are available for special circumstances.

Transmission Rate

By default the fastest possible transmission rate will be selected. You have the option of selecting the speed if
necessary.

Number of Spatial Streams

Selecting more than one spatial stream can increase throughput, but can in some cases decrease signal
quality. Select the option that works best for your installation.

Visibility Status

The Invisible option allows you to hide your wireless network. When this option is set to Visible, your wireless
network name is broadcast to anyone within the range of your signal. If you're not using encryption then they
could connect to your network. When Invisible mode is enabled, you must enter the Wireless Network Name
(SSID) on the client manually to connect to the network.

Security Mode

Unless one of these encryption modes is selected, wireless transmissions to and from your wireless network
can be easily intercepted and interpreted by unauthorized users.

WEP

A method of encrypting data for wireless communication intended to provide the same level of privacy as a
wired network. WEP is not as secure as WPA encryption. To gain access to a WEP network, you must know
the key. The key is a string of characters that you create. When using WEP, you must determine the level of
encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key than
64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or
ASCII (American Standard Code for Information Interchange - alphanumeric characters) format. ASCII format
is provided so you can enter a string that is easier to remember. The ASCII string is converted to HEX for use
over the network. Four keys can be defined so that you can change keys easily. A default key is selected for
use on the network.

10

Example:

64-bit hexadecimal keys are exactly 10 characters in length. (12345678FA is a valid string of 10 characters for
64-bit encryption.)

128-bit hexadecimal keys are exactly 26 characters in length. (456FBCDF123400122225271730 is a valid
string of 26 characters for 128-bit encryption.)

64-bit ASCII keys are up to 5 characters in length (DMODE is a valid string of 5 characters for 64-bit
encryption.)

128-bit ASCII keys are up to 13 characters in length (2002HALOSWIN1 is a valid string of 13 characters for
128-bit encryption.)

Note that, if you enter fewer characters in the WEP key than required, the remainder of the key is
automatically padded with zeros.

WPA-Personal and WPA-Enterprise

Both of these options select some variant of Wi-Fi Protected Access (WPA) -- security standards published by

the Wi-Fi Alliance. The WPA Mode further refines the variant that the access point should employ.
WPA Mode: WPA is the older standard; select this option if the clients that will be used with the access point

only support the older standard. WPA2 is the newer implementation of the stronger IEEE 802.11i security
standard. With the "WPA2" option, the access point tries WPA2 first, but falls back to WPA if the client only
supports WPA. With the "WPA2 Only" option, the access point associates only with clients that also support
WPA2 security.

Cipher Type: The encryption algorithm used to secure the data communication. TKIP (Temporal Key Integrity

Protocol) provides per-packet key generation and is based on WEP. AES (Advanced Encryption Standard) is
a very secure block based encryption. With the "TKIP and AES" option, the access point negotiates the cipher
type with the client, and uses AES when available.

Group Key Update Interval: The amount of time before the group key used for broadcast and multicast data

is changed.

WPA-Personal

This option uses Wi-Fi Protected Access with a Pre-Shared Key (PSK).

Pre-Shared Key: The key is entered as a pass-phrase of up to 63 alphanumeric characters in ASCII

(American Standard Code for Information Interchange) format at both ends of the wireless connection. It
cannot be shorter than eight characters, although for proper security it needs to be of ample length and should
not be a commonly known phrase. This phrase is used to generate session keys that are unique for each
wireless client.

Example:
Wireless Networking technology enables ubiquitous communication

WPA-Enterprise

This option works with a RADIUS Server to authenticate wireless clients. Wireless clients should have
established the necessary credentials before attempting to authenticate to the Server through this Gateway.
Furthermore, it may be necessary to configure the RADIUS Server to allow this Gateway to authenticate
users.

Authentication Timeout: Amount of time before a client will be required to re-authenticate.
RADIUS Server IP Address: The IP address of the authentication server.
RADIUS Server Port: The port number used to connect to the authentication server.
RADIUS Server Shared Secret: A pass-phrase that must match with the authentication server.
MAC Address Authentication: If this is selected, the user must connect from the same computer whenever

logging into the wireless network.

Advanced:

11

Optional Backup RADIUS Server

This option enables configuration of an optional second RADIUS server. A second RADIUS server can be
used as backup for the primary RADIUS server. The second RADIUS server is consulted only when the

primary server is not available or not responding. The fields Second RADIUS Server IP Address, RADIUS
Server Port, Second RADIUS server Shared Secret, Second MAC Address Authentication provide the

corresponding parameters for the second RADIUS Server

12

Basic_Network Settings

Access Point Settings

These are the settings of the LAN (Local Area Network) interface for the access point. The access point's local
network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this section.
The IP address is also used to access this Web-based management interface. It is recommended that you
use the default settings if you do not have an existing network.

13

DHCP Server Settings

DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in
DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN).

Enable DHCP Server

Once your access point is properly configured and this option is enabled, the DHCP Server will manage the IP
addresses and other network configuration information for computers and other devices connected to your
Local Area Network. There is no need for you to do this yourself.

The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to
"DHCP" or "Obtain an IP address automatically".

When you set Enable DHCP Server, the following options are displayed.

DHCP IP Address Range

These two IP values (from and to) define a range of IP addresses that the DHCP Server uses when assigning

addresses to computers and devices on your Local Area Network. Any addresses that are outside of this
range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices
or devices that cannot use DHCP to obtain network address details automatically.

It is possible for a computer or device that is manually configured to have an address that does reside within
this range. In this case the address should be reserved (see DHCP Reservation
Server knows that this specific address can only be used by a specific computer or device.

Your access point, by default, has a static IP address of 192.168.2.2. This means that addresses 192.168.2.3
to 192.168.2.254 can be made available for allocation by the DHCP Server.

below), so that the DHCP

Example:

Your access point uses 192.168.2.2 for the IP address. You've assigned a computer that you want to
designate as a Web server with a static IP address of 192.168.2.3. You've assigned another computer that
you want to designate as an FTP server with a static IP address of 192.168.2.4. Therefore the starting IP
address for your DHCP IP address range needs to be 192.168.2.5 or greater.

Example:

Suppose you configure the DHCP Server to manage addresses From 192.168.2.100 To 192.168.2.199. This
means that 192.168.2.3 to 192.168.2.99 and 192.168.2.200 to 192.168.2.254 are NOT managed by the
DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured.
Suppose you have a web server computer that has a manually configured address of 192.168.2.100. Because
this falls within the "managed range" be sure to create a reservation for this address and match it to the
relevant computer (see Static DHCP Client below).

DHCP Lease Time

The amount of time that a computer may have an IP address before it is required to renew the lease. The
lease functions just as a lease on an apartment would. The initial lease designates the amount of time before
the lease expires. If the tenant wishes to retain the address when the lease is expired then a new lease is
established. If the lease expires and the address is no longer needed than another tenant may use the
address.

Always Broadcast

If all the computers on the LAN successfully obtain their IP addresses from the access point's DHCP server as
expected, this option can remain disabled. However, if one of the computers on the LAN fails to obtain an IP
address from the access point's DHCP server, it may have an old DHCP client that incorrectly turns off the
broadcast flag of DHCP packets. Enabling this option will cause the access point to always broadcast its
responses to all clients, thereby working around the problem, at the cost of increased broadcast traffic on the
LAN.

NetBIOS Advertisement

Check this box to allow the DHCP Server to offer NetBIOS configuration settings to the LAN hosts. NetBIOS
allow LAN hosts to discover all other computers within the network, e.g. within Network Neighbourhood.

14

Primary WINS Server IP address

Configure the IP address of the preferred WINS server. WINS Servers store information regarding network
hosts, allowing hosts to 'register' themselves as well as discover other available hosts, e.g. for use in Network
Neighbourhood.

Secondary WINS Server IP address

Configure the IP address of the backup WINS server, if any.

NetBIOS Scope

This is an advanced setting and is normally left blank. This allows the configuration of a NetBIOS 'domain'
name under which network hosts operate.

NetBIOS Registration mode

Indicates how network hosts are to perform NetBIOS name registration and discovery.
H-Node, this indicates a Hybrid-State of operation. First WINS servers are tried, if any, followed by local
network broadcast. This is generally the preferred mode if you have configured WINS servers.
M-Node (default), this indicates a Mixed-Mode of operation. First Broadcast operation is performed to register
hosts and discover other hosts, if broadcast operation fails, WINS servers are tried, if any. This mode favours
broadcast operation which may be preferred if WINS servers are reachable by a slow network link and the
majority of network services such as servers and printers are local to the LAN.
P-Node, this indicates to use WINS servers ONLY. This setting is useful to force all NetBIOS operation to the
configured WINS servers. You must have configured at least the primary WINS server IP to point to a working
WINS server.
B-Node, this indicates to use local network broadcast ONLY. This setting is useful where there are no WINS
servers available, however, it is preferred you try M-Node operation first.

Add/Edit DHCP Reservation

This option lets you reserve IP addresses, and assign the same IP address to the network device with the
specified MAC address any time it requests an IP address. This is almost the same as when a device has a
static IP address except that the device must still request an IP address from the access point. The access
point will provide the device the same IP address every time. DHCP Reservations are helpful for server
computers on the local network that are hosting applications such as Web and FTP. Servers on your network
should either use a static IP address or use this option.

Enable

Specifies whether the entry will be active or inactive.

Computer Name

You can assign a name for each computer that is given a reserved IP address. This may help you keep track
of which computers are assigned this way. Example:

IP Address:

The LAN address that you want to reserve.

MAC Address

To input the MAC address of your system, enter it in manually or connect to the access point's

Web-Management interface from the system and click the Copy Your PC's MAC Address button.

A MAC address is usually located on a sticker on the bottom of a network device. The MAC address is
comprised of twelve digits. Each pair of hexadecimal digits are usually separated by dashes or colons such as
00-0D-88-11-22-33 or 00:0D:88:11:22:33. If your network device is a computer and the network card is
already located inside the computer, you can connect to the access point from the computer and click the

Copy Your PC's MAC Address button to enter the MAC address.

As an alternative, you can locate a MAC address in a specific operating system by following the steps below:

Game Server.

DHCP Reservations List

This shows clients that you have specified to have reserved DHCP addresses. Click the Enable checkbox at
the left to directly activate or de-activate the entry. An entry can be changed by clicking the Edit icon or can be
deleted by clicking the Delete icon. When you click the Edit icon, the item is highlighted, and the "Edit DHCP
Reservation" section is activated for editing.

Advanced

The Advanced tab provides the following configuration options: MAC Address Filter, Advanced Wireless,
WISH, Wi-Fi Protected Setup

Advanced_ MAC Address Filter

The MAC address filter section can be used to filter network access by machines based on the unique MAC addresses
of their network adapter(s). It is most useful to prevent unauthorized wireless devices from connecting to your network.
A MAC address is a unique ID assigned by the manufacturer of the network adapter.

16 -- MAC Filtering Rules

Configure MAC Filtering

When "OFF" is selected, MAC addresses are not used to control network access. When "ALLOW" is selected,
only computers with MAC addresses listed in the MAC Address List are granted network access. When
"DENY" is selected, any computer with a MAC address listed in the MAC Address List is refused access to
the network.

MAC Address

Enter the MAC address of the desired. Computers that have obtained an IP address from the access point's
DHCP server will be in the DHCP Client List. Select a device from the drop down menu, then click the arrow
to add that device's MAC address to the list.

Clear

Click the Clear button to remove the MAC address from the MAC Filtering list.

Advanced_Advanced Wireless

Transmit Power

Normally the wireless transmitter operates at 100% power. In some circumstances, however, there might be a
need to isolate specific frequencies to a smaller area. By reducing the power of the radio, you can prevent
transmissions from reaching beyond your corporate/home office or designated wireless area.

Beacon Period

Beacons are packets sent by a wireless access point to synchronize wireless devices. Specify a Beacon
Period value between 20 and 1000. The default value is set to 100 milliseconds.

RTS Threshold

When an excessive number of wireless packet collisions are occurring, wireless performance can be
improved by using the RTS/CTS (Request to Send/Clear to Send) handshake protocol. The wireless
transmitter will begin to send RTS frames (and wait for CTS) when data frame size in bytes is greater than the
RTS Threshold. This setting should remain at its default value of 2346 bytes.

Fragmentation Threshold

Wireless frames can be divided into smaller units (fragments) to improve performance in the presence of RF
interference and at the limits of RF coverage. Fragmentation will occur when frame size in bytes is greater
than the Fragmentation Threshold. This setting should remain at its default value of 2346 bytes. Setting the
Fragmentation value too low may result in poor performance.

18

DTIM Interval

A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages.
When the wireless access point has buffered broadcast or multicast messages for associated clients, it sends
the next DTIM with a DTIM Interval value. Wireless clients detect the beacons and awaken to receive the
broadcast and multicast messages. The default value is 1. Valid settings are between 1 and 255.

Wireless Isolation

Enabling Wireless Isolation prevents associated wireless clients from communicating with each other.

WMM Enable

Enabling WMM can help control latency and jitter when transmitting multimedia content over a wireless
connection.

Short GI

Using a short (400ns) guard interval can increase throughput. However, it can also increase error rate in some
installations, due to increased sensitivity to radio-frequency reflections. Select the option that works best for
your installation.

Extra Wireless Protection

Extra protection for neighboring 11b wireless networks. Turn this option off to reduce the adverse effect of

legacy wireless networks on 802.11ng performance. This option is available only when 802.11 Mode is set to
an 11n Only option. (Refer to the Basic → Wireless

page.)

WDS Enable

When WDS is enabled, this access point functions as a wireless repeater and is able to wirelessly
communicate with other APs via WDS links. Note that WDS is incompatible with WPA -- both features cannot
be used at the same time. A WDS link is bidirectional; so this AP must know the MAC Address (creates the
WDS link) of the other AP, and the other AP must have a WDS link back to this AP. Make sure the APs are
configured with same channel number.

WDS AP MAC Address

Specifies one-half of the WDS link. The other AP must also have the MAC address of this AP to create the
WDS link back to this AP. Enter a MAC address for each of the other APs that you want to connect with WDS.
