DESCRIPTION

Wireless Network Setup

Band

This shows the wireless band which this radio profile is using.

2.4GHz

is the frequency used

by IEEE 802.11b/g/n wireless clients while

5GHz

is used by IEEE 802.11a/ac wireless

clients.

Wireless

You can

Enable

Disable

the wireless LAN in this field.

Channel

Use

Auto

to have the VMG automatically determine a channel to use.

Bandwidth

Select whether the VMG uses a wireless channel width of

20MHz

40MHz

80MHz

A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz

channel uses two standard channels and offers speeds of up to 300 Mbps.

40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase

throughput. The wireless clients must also support 40 MHz. It is often better to use the 20

MHz setting in a location where the environment hinders the wireless signal.

An 80MHz channel groups

adjacent 40MHz channels into pairs to increase bandwidth even

higher.

Select

20MHz

if you want to lessen radio interference with other wireless devices in your

neighborhood or the wireless clients do not support channel bonding.

Control

Sideband

This is available for some regions when you select a specific channel and set the Bandwidth

field to

40MHz

. Set whether the control channel (set in the

Channel

field) should be in the

Lower

Upper

range of channel bands.

Passphrase

Type

If you set security for the wireless LAN and have the VMG generate a password, the setting

in this field determines how the VMG generates the password.

Select

None

to set the VMG’s password generation to not be based on a passphrase.

Select

Fixed

to use a 16 character passphrase for generating a password.

Select

Variable

to use a 16 to 63 character passphrase for generating a password.

Passphrase Key

For a fixed type passphrase enter 16 alphanumeric characters (0-9, A-Z, with no spaces). It

must contain both letters and numbers and is case-sensitive.

For a variable type passphrase enter 16 to 63 alphanumeric characters (0-9, A-Z, with no

spaces). It must contain both letters and numbers and is case-sensitive.

Wireless Network Settings

Wireless

Network Name

(SSID)

The SSID (Service Set IDentity) identifies the service set with which a wireless device is

associated. Wireless devices associating to the access point (AP) must have the same SSID.

Enter a descriptive name (up to 32 English keyboard characters) for the wireless LAN.

Max Clients

Specify the maximum number of clients that can connect to this network at the same time.

Hide SSID

Select this check box to hide the SSID in the outgoing beacon frame so a station cannot

obtain the SSID through scanning using a site survey tool.

Multicast

Forwarding

Select this check box to allow the VMG to convert wireless multicast traffic into wireless

unicast traffic.

Max. Upstream

Bandwidth

Specify the maximum rate for upstream wireless traffic to the WAN from this WLAN in

kilobits per second (Kbps).

Max.

Downstream

Bandwidth

Specify the maximum rate for downstream wireless traffic to this WLAN from the WAN in

kilobits per second (Kbps).

BSSID

This shows the MAC address of the wireless interface on the VMG when wireless LAN is

enabled.

VMG3926-B10A User’s Guide

7.2.1

No Security

Select

No Security

to allow wireless stations to communicate with the access points without any

data encryption or authentication.

Note: If you do not enable any wireless security on your VMG, your network is accessible

to any wireless networking device that is within range.

Figure 31

Wireless > General: No Security

The following table describes the labels in this screen.

7.2.2

Basic (WEP Encryption)

WEP encryption scrambles the data transmitted between the wireless stations and the access points

(AP) to keep network communications private. Both the wireless stations and the access points

must use the same WEP key.

Note: WEP is extremely insecure. Its encryption can be broken by an attacker, using

widely-available software. It is strongly recommended that you use a more

effective security mechanism. Use the strongest security mechanism that all the

wireless devices in your network support. For example, use WPA-PSK or WPA2-PSK

if all your wireless devices support it, or use WPA or WPA2 if your wireless devices

support it and you have a RADIUS server. If your wireless devices support nothing

stronger than WEP, use the highest encryption level available.

Your VMG allows you to configure up to four 64-bit or 128-bit WEP keys but only one key can be

enabled at any one time.

Security Mode

Select

Basic (WEP, 802.1X)

More Secure (WPA(2)-PSK)

to add security on this

wireless network. The wireless clients which want to associate to this network must have

same wireless security settings as the VMG. When you select to use a security, additional

options appears in this screen.

Or you can select

No Security

to allow any client to associate this network without any data

encryption or authentication.

See the following sections for more details about this field.

The following table describes the labels in this screen.

7.2.3

More Secure (WPA(2)-PSK)

The WPA-PSK security mode provides both improved data encryption and user authentication over

WEP. Using a Pre-Shared Key (PSK), both the VMG and the connecting client share a common

password in order to validate the connection. This type of encryption, while robust, is not as strong

as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a newer, more robust version of

the WPA encryption standard. It offers slightly better security, although the use of PSK makes it

less robust than it could be.

Click

General

will not be configurable when you select this option.

Password 1~4

The password (WEP keys) are used to encrypt data. Both the VMG and the wireless stations

must use the same password (WEP key) for data transmission.

If you chose

64-bit

WEP, then enter any 5 ASCII characters or 10 hexadecimal characters

("0-9", "A-F").

If you chose

128-bit

WEP, then enter 13 ASCII characters or 26 hexadecimal characters

("0-9", "A-F").

You must configure at least one password, only one password can be activated at any one

time.
