Authentication Type

: The default is set to “

Auto Select

”, which allows

“

Open System

” or “

Shared Key

” authentication to be used. Select

“

Shared Key

” if you only want to use “

Shared Key

” authentication (the

sender and recipient both must use the same WEP key for

authentication).

h

Fragmentation Threshold:

This value specifies the maximum size for a

packet before data is fragmented into multiple packets. You should

leave this value in the 256 to 2346 range. In most cases, it should

remain as its default value of 2346. Setting the Fragmentation

Threshold too low may result in poor network performance.

h

RTS Threshold:

You can set RTS Threshold value in this field, the valid

range should be 256-2347 and default value is 2347. If a network

packet is smaller than the preset RTS threshold size, the RTS/CTS

mechanism will not be enabled.

h

DTIM Interval:

The “

DTIM Interval

” indicates the interval of the

Delivery Traffic Indication Message, you can set this value in the

20-1000 range, and the default value is 100.

h

Transmit Rate:

Transmit rate indicates the transmission speed of

wireless LAN access .The default setting is “

Auto

” and you can set this

value between 1 – 54Mbps range.

h

802.11g Protection:

Using 802.11b and 802.11g mixed mode may

result in poor network performance. By enabling the 802.11 protection,

it will improve performance of 802.11g devices in your wireless

network.

h

Preamble Type:

"

Short Preamble

" is suitable for heavy traffic wireless

network which will significantly increase the throughput performance at

higher data rates. While "

Long Preamble

" provides more

communication reliability and will ensure maximum stability of the

connection; the default setting is “

Long Preamble

”.

h

AP Isolation:

Create separate virtual networks for your wireless

network. After enable this function, every wireless client will in its own

virtual network and can not access each other. If many users access

your wireless network frequently, you should enable this function.

differently from the Primary SSID; otherwise, you might not be able to direct your

Wireless Adapter to connect to it.

3.5.3 AP Sharing Technique

By default, the primary AP and the secondary AP are sharing under same IP

Range; as “

AP Sharing Technique

” is Enable.

You can also “

Disable

” the AP Sharing Technique to have the Primary AP and the

Secondary AP use different sets of IP range. You will then be asking to set

another IP segment for your secondary SSID.

3.6 RNX-GX4’s LAN Setup Page

You can click on “

LAN Setup

” to manage your Router’s Local network IP address

“

LAN IP address

” (LAN port’s IP address) and DHCP server. When finish setup, this

IP Address will be use as the Default Gateway IP address for your computer (Router’s

factory setting for IP Address/Subnet Mask is

192.168.1.1

/

225.225.225.0

)

h

IP Address: This is the IP address of your Router in the Local Network

h

Subnet Mask: This is the Subnet Mask of your Router in Local Network.

“

LAN Setup

” also provides you with the management ability for “

DHCP server

”.

h

DHCP Server Status: to enable or disable your Router’s DHCP server

function (Factory default as Enable)

h

IP Address Pool: the IP address range can be distributed by your

3.7 RNX-GX4’s Advance Usage -

Applications and Gaming Page

This section provides functions which you can utilize to help optimize the internet

speed for some of the games and applications.

3.7.1 Virtual Service

The Virtual Service of RNX-GX4 provides port mapping from LAN to WAN where

all outside visits to this port will be redirect to the designated computer within this

service. You can set different protocol and for both the external and internal port

range depending on your needs.

Dynamic Host Configuration Protocol

(

DHCP

) server will automatically assign an IP address for all

computers that connect to it. Internet protocol (TCP/IP) includes IP address, subnet mask, Gateway,

DNS server, and other information. It is very complicated to set TCP/IP for all computers within the

Local Network, therefore many Routers will set to enable DHCP server as default. When enable

DHCP server, your computer will also need to set “Obtain an IP address automatically” and “Obtain

DNS server address automatically”.

If you changed “LAN IP Address” in the Router, you will need to use the new set of IP address to log

back in to the Router, and all of your computers’ IP addresses will need to change, in order to access

internet.

Description

: This is for your reference of the name of the Virtual Server

you will be using. You can type in your preferences.

h

Internal Host IP Address

:

Internal Host IP Address refers to the

internal computer’s IP address that you want to use. This internal

computer’s IP address preferable to be manually set so you won’t have

to change every time you restart the computer.

h

Protocol

: Protocols are the protocol type that you want to set for your

internal host. For example, if you have a web server, you can set the

protocol as HTTP.

h

External Port

: This is referring to the port which broadcast by your

RNX-GX4. You can enter a range of the port for this setting. For

example, 80~90.

h

Internal Port

: This is referring to the specific service TCP/UDP port of

your internal host. For example, if you have a web server IP as

192.168.1.110, internal port 80, then you can set this virtual service like

the picture above.

IMPORTANT

:

If you set your port as 8080, you will need to change the 8080 port in the “

Remote Management

Port

” under “

Firewall

” of “

Security Management

” to the other port. Otherwise, this may cause a

conflict between the Virtual Service and Remote Management.

3.7.2 DMZ

Some programs require having multiple port connection, such as Internet Gaming

programs, Video Conferencing programs, and Internet Phones. Due to the firewall

limitation, these programs will not be able to work under virtual service. The

purpose of a DMZ is to add an additional layer of security to your Local Area

Network (LAN); an external attacker only has access to equipment in the DMZ,

rather than the whole of the network.
