INFORMATION

Networking

 Depending on the network environment at your premise, cases below may occur.

 Unable to obtain a maximum communication speed.
 Unable to obtain a stable communication speed.
 Unable to establish a communication link.

 If your network is connected to an external network, threats of unauthorized

intrusion and information leak may increase. Install firewall software on your PCs
connected to the Gateway as necessary.

Wireless LAN
 Standard values of up to 300 Mbps, 54 Mbps, and 11 Mbps present theoretical

maximum values of IEEE 802.11 Wireless LAN Standard and do not present actual
(effective) data throughput values.

 Reachable distance and communication speed of the wireless LAN facility built in

the Gateway largely differ with environmental conditions at your premise. These
conditions include communication distances, electromagnetic factors (such as
obstacles and microwave appliances), performances of connected PCs, and
network usage rates.

 When an IEEE 802.11b device, an IEEE 802.11g device, and an IEEE 802.11n

device coexist in the network at your premise, the throughput of the IEEE 802.11n
device may become significantly slow.

 To enable communications with an IEEE 802.11n device, wireless encryption on

the wireless LAN terminal must be set to “-” (no encryption), “WPA-PSK (AES),” or
“WPA2-PSK (AES),” where the last choice is recommended.

 WLAN channels 12 and 13 are not allowed to use. Your configuration of wireless

channel 12 or 13 is invalid.

Firmware upgrade
 In order to keep the firmware of the Gateway up to date, the Gateway automatically

checks for a new firmware version over an applicable external network and, if a new
version is found, upgrades the installed firmware within the predefined timeframe.

 During execution of firmware upgrade, all other connections are automatically

disconnected.

 Execution of firmware upgrade may interrupt your use of services via an external

network such as viewing streaming content. If this happens, wait until execution of
firmware upgrade is complete and then retry use of the interrupted service.

INFORMATION

Management of site-specific information
 The Gateway can register and store information that is specific to you and your

premise. If such site-specific information leaks, your loss may be unpredictable.
Take utmost care in managing such site-specific information stored in the Gateway.

 You can completely erase the site-specific information by initializing the Gateway.

Follow the procedure in Section 8.1, “Initialization of the Gateway.”

INFORMATION

 Because wireless LAN uses radio waves instead of LAN cables for communications

among devices such as PCs through wireless LAN access points, it has the benefit
of LAN connection anywhere as far as radio waves can reach.

 Conversely, without proper security settings, wireless LAN may be susceptible to

the following threats because radio waves can reach anywhere within their scope
beyond obstacles such as walls:
 Sniffing: A malicious third party may willfully intercept radio waves, thus

stealing the content of communications such as e-mails or personal information
such as user IDs, passwords, and credit-card numbers.

 Unauthorized intrusion: A malicious third party may intrude on the personal or

corporate network without consent, and either steal personal or confidential
information (leaking), spread false information while impersonating a particular
person (spoofing), overwrite intercepted communications (tampering), or spread
malware to corrupt data and crash the system (destroying).

 Most wireless LAN adapters and wireless LAN access points are equipped with

security measures against the above-mentioned threats. By configuring the
settings of such security measures properly, the user can minimize the
susceptibility of the user’s wireless LAN system to these threats.

 Some wireless LAN adapters and wireless LAN access points may ship with

security settings not configured by default. Accordingly, in order to minimize
possible threats to the user’s wireless LAN system, the user is required to configure
all security settings before the user starts using wireless LAN adapters and wireless
LAN access points.

 By design, wireless LAN is still susceptible to security breach via special methods.

Use wireless LAN with this in mind.

 The Manufacturer advises the user to configure, at the user’s own judgement and

responsibility, all security settings on wireless LAN devices properly before use,
based on the user’s full understanding of possible threats when such settings are
not made.

 The Manufacturer disclaims any loss due to the user’s failure in configuring proper

security settings on wireless LAN devices or due to security breach inevitable by
design of wireless LAN.

INFORMATION

 In order to keep the firmware of the Gateway up to date, the Gateway automatically

checks for a new firmware version over an applicable external network and, if a new
version is found, upgrades the firmware as scheduled. For the purpose of this
automatic firmware upgrade, a new version firmware file is downloaded in the
Gateway upon finding over the external network or, if the connection is busy, at the
time of upgrading the firmware.

 During upgrading of the firmware initiated by manual firmware upgrade, the ALARM

lamp in the front access area of the Gateway blinks in orange.

 While firmware upgrade is in progress, do not disconnect power until installation of

a new firmware version is finished. Otherwise, firmware upgrade will not complete
successfully.

 When the Gateway has downloaded a new version firmware file and is manually

restarted before the predefined timeframe by unplugging and plugging the power
cord, the Gateway starts up in the new firmware version.

 When the Gateway starts up in the state of factory shipment and a new firmware

version is found after this startup process, the Gateway automatically upgrades the
firmware. Wait until downloading of a new version firmware file, restarting of the
Gateway, and upgrading of the firmware are all complete.

 For the purpose of upgrading the firmware, the Gateway automatically restarts and

all network connections temporarily get disconnected. Accordingly, terminate the
ongoing communications, if any (such as communications with the user PC
connected to the network), before upgrading of the firmware takes place.

 Operation of manual firmware upgrade is not available during upgrading of the

firmware, during task scheduling for automatic firmware upgrade, during restarting
of the Gateway, or during any setting/maintenance operation.

 Firmware upgrade does not guarantee upgrading of all functions to the latest.
 Use a firmware version applicable to the Gateway whenever you perform firmware

upgrade. Otherwise, the Gateway may become inoperative.

 Firmware upgrade may not always keep your settings. It is hence recommended

When automatic firmware upgrade is running, firmware upgrade by click the Check
the Upgrade button fails with the message "error! firm ware upgrade failed". At that

time, please try to firmware upgrade again a few minutes later.

6.3 Automatic Firmware Upgrade Procedure

With automatic firmware upgrade function enabled by default, the Gateway automatically
checks if a new version firmware file is uploaded on the dedicated server on an
applicable external network and, when a new version firmware file is found, upgrades the
firmware as scheduled. For the purpose of this automatic firmware upgrade, a new
version firmware file is downloaded in the Gateway upon finding on the server or, if the
connection is busy, at the time of upgrading the firmware.

The said checking for a new version firmware file is performed once within 24 hours of
initial startup of the Gateway and once per day thereafter.

The timeframe for upgrading the firmware is set by default to a certain hour of day
between 1 a.m. to 5 a.m. and actual time for upgrading the firmware will take about one
minute within the preset hour of day. For example, if the timeframe is set to 3 a.m., the
actual time for upgrading the firmware will be about one minute between 3:00 a.m. to
3:59 a.m.

Security Encryption Key values match between
the Gateway and the user PC. In particular
when WEP is in use, ensure that the values of
WEP Key Index and WEP Keys #1 to #4 match
between the Gateway and the user PC.

 When MAC address filtering is in use, ensure

that the MAC address of the user PC is
registered to the Gateway according to the
procedure of Section 5.2.

 Wireless LAN connection may fail when the

encryption setting of an IEEE 802.11n-based
user PC is “WPA-PSK (TKIP)” or “WPA2-PSK
(TKIP).” To ensure communications with an
IEEE 802.11n-based user PC, change the
encryption setting to “WPA-PSK (AES)” or
“WPA2-PSK (AES),” where the latter is
recommended. As an alternative, if
applicable, change the operation mode of the
user PC to IEEE 802.11g or IEEE 802.11b.

LAN terminals cannot communicate
with one another.

LAN terminals may not support communications
based on domain names. Try not to use domain
names.

INFORMATION

 Log-in authentication settings of user ID and password are important personal

information which, if stolen, may be abused. Take utmost care in managing your
user ID and password.

 Initialization completely deletes the settings you made to the Gateway. It is

advised that you back up the current settings onto a hard disk of your PC or similar
medium before you perform initialization.

8. APPENDIX

8.1 Initialization of the Gateway

Initialization means deletion of settings made after installation of the Gateway, thereby
restoring the Gateway to the state of factory shipment. When the Gateway does not
operate properly or when the Gateway is to participate in a completely different network,
it is recommended that you initialize the Gateway and set up the Gateway from scratch.

Be noted, however, that this initialization completely deletes the settings you made to the
Gateway. It is advised that you back up the current settings onto an external medium
before you perform initialization.

To perform initialization, follow the steps below.

1. Unplug the power cord from the outlet to turn off power of the Gateway.

2. While pressing down the INIT button in the rear access area of the Gateway (see

Section 1.2 for the button location), plug the power cord into the outlet to turn on
power of the Gateway.

3. Keep pressing down the INIT button for 10 seconds or longer. The Gateway starts

up in the state of factory shipment.
