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.

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.

Isolate

LAN – Check this box to make the wireless clients

(stations) with the same SSID cannot access wired

PCs on LAN.

Member –Check this box to make the wireless

clients (stations) with the same SSID not accessing

for each other.

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.

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 filed 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.

Packet-OVERDRIVE This feature can enhance the performance in data

transmission about 40%* more (by checking Tx Burst).

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 activating TxBurst).
