Enable Wireless LAN

Check the box to enable wireless function.

Mode

At present, the router can connect to Mixed (11b+11g),

11g Only, 11b Only, Mixed (11g+11n), 11n Only and

Mixed (11b+11g+11n) stations simultaneously. Simply

choose Mix (11b+11g+11n) mode.

Note:

You should also set

RADIUS Server

simultaneously if 11g Only, 11b Only or 11n Only

mode is

selected.

Index(1-15)

Set the wireless LAN to work at certain time interval only.

You may choose up to 4 schedules out of the 15 schedules

pre-defined in

Applications >> Schedule

setup. The

default setting of this field is blank and the function will

always work.

SSID

Means the identification of the wireless LAN. SSID can be

any text numbers or various special characters. The default

SSID is "DrayTek". We suggest you to change it.

Channel

Means the channel of frequency of the wireless LAN. The

default channel is 6. You may switch channel if the

selected channel is under serious interference. If you have

no idea of choosing the frequency, please select Auto to let

system determine for you.

Packet-OVERDRIVE

This feature can enhance the performance in data

transmission about 40%* more (by checking

Tx Burs

t). It

is active only when both sides of Access Point and Station

(in wireless client) invoke this function at the same time.

That is, the wireless client must support this feature and

invoke the function, too.

Note:

Vigor N61 wireless adapter supports this function.

Therefore, you can use and install it into your PC for

matching with Packet-OVERDRIVE (refer to the

following picture of Vigor N61 wireless utility window,

choose

Enable

for

TxBURST

on the tab of

Option

).

Hide SSID

Check it to prevent from wireless sniffing and make it

harder for unauthorized clients or STAs to join your

wireless LAN. Depending on the wireless utility, the user

may only see the information except SSID or just cannot

see any thing about Vigor wireless router while site

surveying. The system allows you to set four sets of SSID

for different usage. In default, the first set of SSID will be

enabled. You can hide it for your necessity.

Long Preamble

This option is to define the length of the sync field in an

802.11 packet. Most modern wireless network uses short

preamble with 56 bit sync field instead of long preamble

with 128 bit sync field. However, some original 11b

wireless network devices only support long preamble.

Check it to use

Long Preamble

if needed to communicate

with this kind of devices.

3.6.3 Security

By clicking the

Security Settings

, a new web page will appear so that you could configure the

settings of WEP and WPA.

Mode

There are several modes provided for you to choose.

Disable

- Turn off the encryption mechanism.

WEP-

Accepts only WEP clients and the encryption key

should be entered in WEP Key.

WPA/PSK-

Accepts only WPA clients and the encryption

key should be entered in PSK.

WPA2/PSK-

Accepts only WPA2 clients and the

encryption key should be entered in PSK.

Mixed (WPA+ WPA2)/PSK -

Accepts WPA and WPA2

clients simultaneously and the encryption key should be

entered in PSK.

Vigor2110 Series User’s Guide

72

WPA

The WPA encrypts each frame transmitted from the radio

using the key, which either PSK (Pre-Shared Key) entered

manually in this field below or automatically negotiated

via 802.1x authentication. Either

8~63

ASCII characters,

such as 012345678(or 64 Hexadecimal digits leading by 0x,

such as "0x321253abcde...").

Type

- Select from Mixed (WPA+WPA2) or WPA2 only.

Pre-Shared Key (PSK)

- Either

8~63

ASCII characters,

such as 012345678..(or 64 Hexadecimal digits leading by

0x, such as "0x321253abcde...").

WEP

64-Bit

-

For 64 bits WEP key, either

5

ASCII characters,

such as 12345 (or 10 hexadecimal digitals leading by 0x,

such as 0x4142434445.)

128-Bit

-

For 128 bits WEP key, either

13

ASCII

characters, such as ABCDEFGHIJKLM (or 26

hexadecimal digits leading by 0x, such as

0x4142434445464748494A4B4C4D).

All wireless devices must support the same WEP

encryption bit size and have the same key.

Four keys

can

be entered here, but only one key can be selected at a time.

The keys can be entered in ASCII or Hexadecimal. Check

the key you wish to use.

3.6.4 Access Control

For additional security of wireless access, the

Access Control

facility allows you to restrict

the network access right by controlling the wireless LAN MAC address of client. Only the

valid MAC address that has been configured can access the wireless LAN interface. By

clicking the

Access Control

, a new web page will appear, as depicted below, so that you

could edit the clients' MAC addresses to control their access rights.

Vigor2110 Series User’s Guide

Enable Mac Access Filter

Select to enable the MAC Address filter for wireless LAN

identified with SSID 1 to 4 respectively. All the clients

(expressed by MAC addresses) listed in the box can be

grouped under different wireless LAN. For example, they

can be grouped under SSID 1 and SSID 2 at the same time

if you check SSID 1 and SSID 2.

MAC Address Filter

Display all MAC addresses that are edited before.

Client’s MAC Address

Manually enter the MAC address of wireless client.

Attribute

s: Isolate the station from LAN -

select to isolate the

wireless connection of the wireless client of the MAC

address from LAN.

Add

Add a new MAC address into the list.

Delete

Delete the selected MAC address in the list.

Edit

Clear All

Clean all entries in the MAC address list.

3.6.5 Advanced Setting

This page allows users to set advanced settings such as operation mode, channel bandwidth,

guard interval, and aggregation MSDU for wireless data transmission.

Operation Mode

Mixed Mode

– the router can transmit data with the ways

supported in both 802.11a/b/g and 802.11n standards.

However, the entire wireless transmission will be slowed

down if 802.11g or 802.11b wireless client is connected.

Green Field

– to get the highest throughput, please choose

such mode. Such mode can make the data transmission

happening between 11n systems only. In addition, it does

not have protection mechanism to avoid the conflict with

neighboring devices of 802.11a/b/g.

Channel Bandwidth

20-

the router will use 20Mhz for data transmission and

receiving between the AP and the stations.

20/40 –

the router will use 20Mhz or 40Mhz for data

transmission and receiving according to the station

capability. Such channel can increase the performance for

data transit.

Guard Interval

It is to assure the safety of propagation delays and

reflections for the sensitive digital data. If you choose

auto
