Example 3

Separate the Wireless and the Wired LAN- WLAN Isolation

enables you to isolate your

wireless LAN from wired LAN for either quarantine or limit access reasons. To isolate means

neither of the parties can access each other. To elaborate an example for business use, you

may set up a wireless LAN for visitors only so they can connect to Internet without hassle of

the confidential information leakage. For a more flexible deployment, you may add a filter of

MAC address to isolate single user’s access from wired LAN.

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

SSID and the wireless channel. Please refer to the following figure for more information.

Enable Wireless LAN

Check the box to enable wireless function.

Mode

Select an appropriate wireless mode.

Mixed (11b+11g) -

The radio can support both

IEEE802.11b and IEEE802.11g protocols simultaneously.

11g only -

The radio only supports IEEE802.11g.

11b only -

The radio only supports IEEE802.11b.

Scheduler (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

Call Schedule Setup

group

setup. The default setting of this filed is blank and

the function will always work.

SSID

The default SSID is "default". We suggest you change it to

a particular name. It is the identification of the wireless

LAN. SSID can be any text numbers or various special

characters.

Channel

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.

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.

Long Preamble

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

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.
