WiFi Settings

Radio On/Off:

WiFi is turned on by default. Changing this option to OFF will turn OFF the wireless functionality on the 4G100W 4G LTE WiFi Router

and you will not be able to connect to your 4G100W 4G LTE WiFi Router wirelessly.

OPTION

DEFINITION

Country

Select the country you are operating the router in.

Network Mode; There are 5 modes to select from:

11b/g mixed mode:

Both 802.11b and 802.11g wireless devices are allowed to connect to your 4G100W 4G LTE WiFi Router.

11b only:

Select this if all of your wireless clients use the 802.11b wireless protocol.

11g only:

Select this if all of your wireless clients use the 802.11g wireless protocol.

11n only:

Select this if all of your wireless clients use the 802.11n wireless protocol.

11/b/g/n Mixed mode:

Select this mode if 802.11b, 802.11g and 802.11n wireless devices are all employed in your network.

Frequency (Channel):

This setting configures the frequency that the Wireless Radio uses for wireless connectivity. Select one channel that you wish to

use from the drop down list.

SSID (Network Name)

The SSID (Service Set Identifier) is the name of your wireless network. Use a unique name to identify your wireless device so that

you can easily connect to it from your wireless clients. This field is case sensitive and can be up to 32 characters long. You should

change the default SSID for added security.

Activate this SSID

Use this option to disable or enable the use of the SSID.

Broadcast this SSID

This option can be used to hide the wireless broadcasting of the SSID so that only informed parties can connect via wireless.

Network Authentication

See the following pages for an explanation of the different security types available.

Advanced

This page allows you to modify the advanced wireless settings for your NetComm 4G100W 4G LTE WiFi Router. These settings

should not be changed unless you are aware of what effect they will have.

OPTION

DEFINITION

BG Protection Mode

A mechanism to enable the router to communicate with older legacy wireless network adapters that use 802.11b and

802.11g wireless protocols.

Client Idle Timeout

The wireless client connections will timeout if there is no data packets transmitted within the specified seconds range.

Beacon Interval:

The interval of time in which the wireless router broadcasts a beacon which is used to synchronize the wireless network.

Data Beacon Rate (DTIM):

Enter a value between 1 and 255 for the Delivery Traffic Indication Message (DTIM). A DTIM is a countdown informing

clients of the next window for listening to broadcast and multicast messages.

Fragment Threshold:

This specifies the maximum size of a packet during the fragmentation of data to be transmitted. If you set this value too

low, it will result in bad performance.

RTS Threshold:

When the packet size is smaller than the RTS threshold, the wireless router will not use the RTS/CTS mechanism to

send this packet.

TX Power:

This determines the transmit or output power of the broadcast wireless signal.

Short Preamble

A radio preamble is a part of a datagram packet at the head of the Physical Layer Convergence Protocol (PLCP) to

increase throughput. Shortening the preamble reduces the size of the data packet increasing throughput. However not

all wireless network adapters are able to use this setting.

Short Slot

The amount of time the router waits after a packet collision before retransmitting the data packet. Enabling the short slot

reduces this time from 20ms to 9ms, therefore increasing overall throughput.

Tx Burst

The Transmission Burst boosts the WLAN data packet throughput to maximise transmission rates according to the

wireless protocol being used. However this may increase the rate of dropped packets due to environmental factors such

as radio interference which can make the optimal wireless data packet transmission rate less than the maximum possible

transmission rate.

Pkt_Aggregate

Packet Aggregation in IP networking is a function that concatenates multiple data packets into a single Transmission Unit

to reduce redundancy and network traffic overhead.

Country Code

The Country Code option controls the wireless channels that the router can broadcast on, defined by each countries

wireless regulations.

AP Isolation:

This feature allows you to isolate clients on your wireless network. To enable communication between the wireless

clients connected to your NetComm Smart Hub 4G set this option to Disabled. To terminate the communication between

the wireless clients set this option to enabled.

MBSSID AP Isolation

The MBSSID AP Isolation function provides isolation among different SSIDs. When enabled this function prevents

wireless client terminals with different SSIDs from communicating with each other.

BSSID

The Broadcast Service Set Identifier. Select ‘Disabled’ to hide the SSID of your NetComm Smart Hub 4G. If disabled,

other people will not be able scan and de

tect this product’s SSID.

WiFi Multimedia

WMM Capable:

The WMM (WiFi MultiMedia) option if enabled supports QoS for experiencing better audio, video and voice in

applications.

WMM Parameters:

Click on the WMM Configuration button to configure the WMM parameters.

Multicast-to-Unicast Converter

Multicast-to-Unicast

This function converts multicast data to unicast data and is disabled by default.

Others

HT TxStream

This option sets the stream number that wireless antenna transmits.

HT RxStream

This option sets the stream number that wireless antenna receives.

HT Physical Mode

Operating Mode

The options available for this field are Mixed Mode or Green Field. The default operation mode is Mixed Mode.

Channel Bandwidth

The channel bandwidth can be set to a mixed 20/40 MHz (the default value) giving an 802.11g connection speed of up

to 150 Mbps and an 802.11n connection speed of up to 300 Mbps. For legacy wireless adapters the Channel

Bandwidth can be set to 20 MHz slowing the connection speed for 802.11g and 802.11n to 54 Mbps and 74 Mbps

respectively as well as providing backward compatibility for older, slower 802.11b/g devices.

Guard Interval

The guard interval is designed to help wireless clients minimise the effects of multipath delays. When you add a guard

time the back portion of useful signal time is copied and appended to the front. The options available for this field are

Long or Auto. The default setting is Auto.

MCS

The Modulation and Coding Scheme (MCS) function sets the modulation, coding and number of spatial channels. The

default MCS value is Auto.

Reverse Direction Grant (RDG)

The Reverse Direction Grant (RDG) function reduces the transmitted data packet collision rate by using the reverse

direction protocol. The RDG improves transmission performance and scalability in a wireless environment. By default the

RDG setting is enabled.

Aggregation MSDU (A-MSDU)

The MAC Service Data Unit (MSDU) Aggregation function wraps multiple Ethernet frames bound for a common

destination in a single 802.11 frame. This reduces the number of required packet headers making the transmission more

efficient.

Auto Block ACK

The 802.11n protocol uses the Auto Block ACK function for security of the data transmission. If a wireless client receives

a unicast A-MPDU (Aggregated MAC Packet Data Unit) frame, it should respond by sending back an ACK frame without

delay. A Block Acknowledgement reduces the number of the ACK frames while providing an individual

acknowledgement of each aggregated data frame.

Decline BA Request

The Decline BA Request function can be set to refuse block acknowledgement requests from wireless clients. By default

this function is disabled.

WDS

The 4G100W supports the configuration of a Wireless Distribution System (WDS). WDS allows you to expand your wireless network

with multiple access points. There are two WDS modes available: Bridged Mode and Repeater Mode.

In Bridged mode, the WDS access points communicate with each other but do not communicate with wireless clients. Bridged

mode is best used in situations where the client machines connect via Ethernet cable. In Repeater mode, the WDS access points

communicate with each other and with wireless clients.
