Link: Restart Device

When the Gateway is restarted, it will disconnect all users, initialize all its interfaces, and load the Operating Sys-

tem Software.

When you make configuration changes, you may be required restart for the changes to take effect.

Broadband

When you click the

Broadband

tab, the

Broadband Status

page appears.

The

Broadband Status

page displays information about the Gateway’s WAN connection(s) to the Internet.

Broadband Status

Line State

May be Up (connected) or Down (disconnected).

Broadband Connection

May be Up (connected) or Down (disconnected).

Downstream Sync Rate

This is the rate at which your connection can download (receive) data on your

DSL line, in kilobits per second.

Upstream Sync Rate

This is the rate at which your connection can upload (send) data on your DSL

line, in kilobits per second.

Modulation

Method of regulating the DSL signal. DMT (Discrete MultiTone) allows connec-

tions to work better when certain radio transmitters are present.

Data Path

Type of path used by the device's processor.

Broadband IPv4 Address

The public IP address of your device, whether dynamically or statically

assigned.

Gateway IPv4 Address

Your ISP's gateway router IP address.

MAC Address

Your Gateway’s unique hardware address identifier.

Primary DNS

The IP Address of the Primary Domain Name Server.

Secondary DNS

The IP Address of the backup Domain Name Server, if available.

Primary DNS Name

The name of the Primary Domain Name Server.

Secondary DNS Name

The name of the backup Domain Name Server, if available.

MTU

Maximum Transmittable Unit before packets are broken into multiple packets.

IPv6

Status

May be

Enabled

or

Unavailable

.

Global Unicast IPv6

Address

The public IPv6 address of your device, whether dynamically or statically

assigned.

Border Relay IPv4

Address

The public IPv4 address of your device.

IPv4 Statistics

Transmit Packets

IPv4 packets transmitted.

Transmit Errors

Errors on IPv4 packets transmitted.

Transmit Discards

IPv4 packets dropped.

IPv6 Statistics

Transmit Packets

IPv6 packets transmitted.

Transmit Errors

Errors on IPv6 packets transmitted.

Transmit Discards

IPv6 packets dropped.

Downstream and Upstream Statistics

SN Margin (db)

Signal to noise margin, in decibels. Reflects the amount of unwanted “noise”

on the DSL line.

Line Attenuation

Amount of reduction in signal strength on the DSL line, in decibels.

Output Power (dBm)

Measure of power output in decibels (dB) referenced to one milliwatt (mW).

Errored Seconds

The number of uncorrected seconds after being down for seven consecutive

seconds.

Loss of Signal

The absence of any signal for any reason, such as a disconnected cable or

loss of power.

Loss of Frame

A signal is detected but cannot sync with signal caused by mismatched proto-

cols, wrong ISP connection configuration, or faulty cable.

FEC Errors

(Forwarded Error Correction errors) Count of received errored packets that

were fixed successfully with out a retry.

CRC Errors

Number of times data packets have had to be resent due to errors in transmis-

sion or reception.

Link: Configure

When you click the

Configure

link, the Broadband

Configure

screen appears. Here you can reconfigure your

type of broaband connection should it change in the future.

◆

Broadband Connection Source

- dsl, ethernet, or auto (automatically detected).

◆

Media

– Auto (the default self-sensing rate), 10M full- or half-duplex, 100M full- or half-duplex, or 1G full- or

half-duplex.

◆

MDI-X

– Auto (the default self-sensing crossover setting), Off, or On.

◆

The WAN connection is automatically configured. However, you can adjust the

Maximum allowable MTU

(Maximum Transmittable Unit) value, if your service provider suggests it. The default 1500 is the maximum

value, but some services require other values. 1492 is common.

If you make any change here, click the

Save

button.

Link: IGMP Stats

When you click the

IGMP Stats

link, the

IGMP Stats

screen appears.

The IGMP Statistics screen reports IGMP Proxy Groups and Multicast Forwarding information. It also displays a

packet counter.
