Setup

This screen allows you to configure basic features of the wireless LAN interface.

You can enable or disable

the wireless LAN interface, hide the network from active scans, set the wireless network name (also known as

SSID) and restrict the channel set based on country requirements.

The Wireless Guest Network function adds

extra networking security when connecting to remote hosts.

Option

Description

Enable Wireless

A checkbox that enables (default) or disables the wireless LAN interface.

When selected,

the Web UI displays Hide Access point, SSID, BSSID and Country settings.

Hide Access Point

Select Hide Access Point to protect the access point from detection by wireless active

scans.

To check AP status in Windows XP, open Network Connections from the start Menu

and select View Available Network Connections.

SSID

[1-32 characters]

Sets the wireless network name.

SSID stands for Service Set Identifier.

All stations must

be configured with the correct SSID to access the WLAN.

If the SSID does not match, that

user will not be granted access.

BSSID

The BSSID is a 48bit identity used to identify a particular BSS (Basic Service Set) within

an area. In Infrastructure BSS networks, the BSSID is the MAC (Media Access Control)

address of the AP (Access Point) and in Independent BSS or ad hoc networks, the BSSID is

generated randomly.

Country

A drop-down menu that permits worldwide and specific national settings.

Each country

listed below enforces specific regulations limiting channel range:

•

USA = worldwide

•

Australia/Japan =

1-14

•

Jordan = 10-13

•

Israel =

1-13

NOTE: Remote wireless hosts cannot scan Guest SSIDs.

3G9W - HSPA 7.2Mbps Wi-Fi Router USER GUIDE

YML902 – 27

5.2

Security

This Router includes a number of security options that provides you with a secure connection to a 3G network.

State-of-the art security includes:

•

WEP / WPA / WPA2 data encryption

•

SPI Firewall

•

VPN Pass-Through

•

MAC address IP filtering

•

Authentication protocols – PAP / CHAP

You can authenticate or encrypt your service on the Wired Equivalent Privacy (WEP) algorithm, which provides

protection against unauthorized access such as eavesdropping.

The following screen appears when Security is selected. The Security page allows you to configure security

features of your Router’s wireless LAN interface. You can set the network authentication method, select data

encryption, specify whether a network key is required to authenticate to this wireless network and specify the

encryption strength.

Click

Save/Apply

to configure the wireless security options.

Select SSID

Your Service Set Identifier (SSID), sets your Wireless Network Name. You can connect multiple

devices including Laptops, Desktop PCs and PDAs to your Wireless Router. To get additional

devices connected, scan for a network, and locate the SSID shown on your Wireless Security

Card. If the SSID does not match, access is denied.

Network

Authentication

This option is used for authentication to the wireless network. Each authentication type has

its own settings as illustrated below. For example, selecting 802.1X authentication will reveal

the RADIUS Server IP address, Port and Key fields.

WEP Encryption will also be enabled.

The settings for WPA authentication are shown below.

WEP Encryption

This option indicates whether data sent over the network is encrypted. The same network

key is used for data encryption and network authentication. Whilst four network keys can be

defined, only one can be used at any one time.

Use the network key found in the drop down list.

Encryption

Strength

This drop-down list box will display when WEP Encryption is enabled.

The key strength is proportional to the number of binary bits comprising the key.

This means that keys with a greater number of bits have a greater degree of security and are

considerably more difficult to crack.

Encryption strength can be set to either 64-bit or 128-

bit.

A 64-bit key is equivalent to 5 ASCII characters or 10 hexadecimal numbers.

A 128-bit

key contains 13 ASCII characters or 26 hexadecimal numbers.

FYI: Each key contains a

24-bit header (an initiation vector) which enables parallel decoding of multiple streams of

encrypted data.

Option

Description

AP Isolation

Select On or Off.

By enabling this feature, wireless clients associated with the Access

Point can be linked.

Band

Channel

Allows selection of a specific channel (1-14) or Auto mode.

Auto Channel Timer

(min)

The Auto Channel times the length it takes to scan in minutes.

54g Rate

In Auto (default) mode, your Router uses the maximum data rate and lowers the data

rate dependent on the signal strength. The appropriate setting is dependent on signal

strength.

Other rates are discrete values between 1 to 54 Mbps.

Multicast Rate

Setting for multicast packet transmission rate.

(1-54 Mbps)

Basic Rate

Sets basic transmission rate.

Fragmentation

Threshold

A threshold (in bytes) determines whether packets will be fragmented and at what size.

Packets that exceed the fragmentation threshold of an 802.11 WLAN will be split into

smaller units suitable for the circuit size. Packets smaller than the specified fragmentation

threshold value however are not fragmented.

Values between 256 and 2346 can be entered but should remain at a default setting of

2346. Setting the Fragmentation Threshold too low may result in poor performance.

RTS Threshold

Request To Send (RTS) specifies the packet size that exceeds the specified RTS threshold,

which then triggers the RTS/CTS mechanism. Smaller packets are sent without using

RTS/CTS. The default setting of 2347 (max length) will disables the RTS Threshold.

DTIM Interval

Delivery Traffic Indication Message (DTIM) is also known as Beacon Rate.

The entry

range is a value between 1 and 65535.

A DTIM is a countdown variable that informs

clients of the next window for listening to broadcast and multicast messages.

When the

AP has buffered broadcast or multicast messages for associated clients, it sends the next

DTIM with a DTIM Interval value.

AP Clients hear the beacons and awaken to receive the

broadcast and multicast messages.

The default is 1.

Beacon Interval

The amount of time between beacon transmissions in is milliseconds.

The default is

100 ms and the acceptable range is 1 – 65535.

The beacon transmissions identify the

presence of an access point.

By default, network devices passively scan all RF channels

listening for beacons coming from access points.

Before a station enters power save

mode, the station needs the beacon interval to know when to wake up to receive the

beacon.

Xpress™

Technology

Broadcom’s Xpress™ Technology is compliant with draft specifications of two planned

wireless industry standards.

It has been designed to improve wireless network efficiency.

Default is disabled.
