Who This Page Is For
This page is for users of the following services. Please take care with making your settings.
- Hikari with FLET'S Course Fixed IP Address Option
- FLET'S Hikari Next Course Fixed IP Address Option
- B FLET'S Course Fixed IP Address Option
- FLET'S Hikari Premium Course Fixed IP Address Option
- FLET'S Hikari Light Course Fixed IP Address Option
- FLET'S ADSL Course Fixed IP Address Option
- BB Entry Course Fixed IP Address Option
Users of the B FLET'S Basic Course and B FLET'S Business Course should not refer to these instructions as those Courses have a Fixed IP address as standard; therefore Asahi Net's Fixed IP address option cannot be applied for and special connection instructions (use of "f." before the User Name, etc.) do not apply.
By applying for Asahi Net's Fixed IP Address Option, one (1) global Fixed IP address will be assigned to your Internet connection.
|User Name *1 *2||f.Asahi Net User ID@atson.net
E.g. firstname.lastname@example.org, email@example.com
|Password *2||The password for the User ID|
|Authentication||PAP (FLET'S ADSL/B FLET'S)|
CHAP (FLET'S Hikari Next/FLET'S Hikari Premium/FLET'S Hikari Light/BB Entry)
|Set to Automatic
If designation of addresses is essential, please use:
*1. If after applying for a Fixed IP Address Option the "f." prefix in not used, a dynamically assigned IP address will continue to be assigned to the connection.
*2. Enter the User Name and Password in lower case characters.
Making an Internet connection
Basically you will refer to instructions supplied by NTT with their equipment to make an Internet connection. The two factors that will determine the setup are 1. the type of equipment you received from NTT, and 2. the operating system of your computer.
What equipment did you receive?
Received a bridge-type ADSL modem?
Typical bridge-type ADSL modems provided with NTT's FLET'S ADSL services are: MN, MNII, MNIII, N, NII and S. With a bridge-type ADSL modem you will need to install PPPoE software into your computer. Please refer to the "What is your computer's OS (operating system)?" section below.
Received a VoIP router-type ADSL modem?
Typical VoIP router-type ADSL modems provided with NTT's FLET'S ADSL services are: MNV, SV and NV. These modems are easy to identify: they have a "V" for "VoIP" in their model name, and they have a "VoIP" lamp.
NTT may have sent you one of these ADSL modems because you told them you are wanting to use an IP-Phone service. Please refer to the documentation received with the ADSL modem for how to configure it. You may also find the following configuration guides of assistance.
Received NTT's Webcaster VoIP-capable router?
Typically NTT will have sent you this if you already have an ADSL modem or media converter but also needed VoIP equipment so that you can use an IP Phone service. Please refer to the documentation received with the equipment for how to configure it. You may also find the following configuration guide of assistance.
Received NTT's CTU router?
Typically NTT will supply you with a CTU router if they have opened one of their FLET'S Hikari Premium lines for you. You will need to configure the CTU with your Asahi Net connection User Name and password so that it connects to the Internet.
What is your computer's OS (operating system)?
Using Windows or Mac (English or Japanese)?
PPPoE is built into the the latest Windows and Mac operating systems. Therefore you should not install NTT's Japanese-language FLET'S Connection Tool software or other PPPoE software. Please refer below to our Engilsh configuration guides.
Using Your Own Broadband Router
With a NTT FLET'S connection line your broadband router will need to be PPPoE (PPP Over Ethernet) and PAP (Password Authentication Protocol) compatible, unless the line is FLET'S Hikari Next in which case your router will need to be PPPoE and CHAP compatible. If you are unsure, please refer to the manufacturer's documentation for details.
When using a broadband router that has not been supplied by NTT, you may encounter problems such as not being able to open some Web pages or Web pages opening slowly. In these cases, please try changing the Maximum Transfer Unit (MTU) setting in the broadband router to 1454. By default the MTU setting for broadband routers not supplied by NTT is 1490, a value of 1454 is more compatible with NTT's FLET'S network.
Asahi Net is unable to assist you with the configuration of your own broadband router. Please refer to the manufacturer's documentation for assistance.
