Advanced Configuration

Wireless-N Home Router

Wireless-G devices are experiencing severe problems and

are not able to transmit to the Router in an environment

with heavy 802.11b traffic. This option boosts the Router’s

ability to catch all Wireless-N and Wireless-G transmissions

but severely decreases performance. To use this option,

keep the default, Auto. To disable this option, select

Disabled.

Beacon Interval Enter a value between 1 and 65,535

milliseconds. The Beacon Interval value indicates the

frequency interval of the beacon. A beacon is a packet

broadcast by the Router to synchronize the wireless

network. The default is 100 milliseconds.

DTIM Interval This value, between 1 and 255, indicates

the interval of the Delivery Traffic Indication Message

(DTIM). A DTIM field is a countdown field informing

clients of the next window for listening to broadcast

and multicast messages. When the Router has buffered

broadcast or multicast messages for associated clients, it

sends the next DTIM with a DTIM Interval value. Its clients

hear the beacons and awaken to receive the broadcast

and multicast messages. The default value is 1.

Fragmentation Threshold This value specifies the

maximum size for a packet before data is fragmented

into multiple packets. If you experience a high packet

error rate, you may slightly increase the Fragmentation

Threshold. Setting the Fragmentation Threshold too low

may result in poor network performance. Only minor

reduction of the default value is recommended. In most

cases, it should remain at its default value of 2346.

RTS Threshold Should you encounter inconsistent data

flow, only minor reduction of the default value, 2347, is

recommended. If a network packet is smaller than the

preset RTS threshold size, the RTS/CTS mechanism will

not be enabled. The Router sends Request to Send (RTS)

frames to a particular receiving station and negotiates

the sending of a data frame. After receiving an RTS, the

wireless station responds with a Clear to Send (CTS) frame

to acknowledge the right to begin transmission. The RTS

Threshold value should remain at its default value of

2347.

Security > Firewall

The Firewall screen is used to configure a firewall that can

filter out various types of unwanted traffic on the Router’s

local network.

SPI Firewall Protection To use firewall protection,

keep the default selection, Enabled. To turn off firewall

protection, select Disabled.

Internet Filter

For the following options, select the option to enable it, or

deselect the option to disable it.

Filter Anonymous Internet Requests This feature makes

it more difficult for outside users to work their way into

your network. This feature is enabled by default. Deselect

this option to allow anonymous Internet requests

Filter Multicast Multicasting allows for multiple

transmissions to specific recipients at the same time. If

multicasting is permitted, then the Router will allow IP

multicast packets to be forwarded to the appropriate

computers. Select this option to filter multicasting. This

option is disabled by default.

Filter Internet NAT Redirection This feature uses port

forwarding to block access to local servers from local

networked computers. Select this option to filter Internet

NAT redirection. This option is disabled by default.

Filter IDENT (Port 113) This feature keeps port 113 from

being scanned by devices outside of your local network.

This feature is enabled by default. Deselect this option to

disable it.

Web Filter

For the following options, select the option to enable it, or

deselect the option to disable it.

Proxy Use of WAN proxy servers may compromise the

Gateway’s security. Denying Proxy will disable access to

any WAN proxy servers. Select this option to enable proxy

filtering. This option is disabled by default.

Java Java is a programming language for websites. If you

deny Java, you run the risk of not having access to Internet

sites created using this programming language. Select
