3. Are you using PPPoE software that has not been supplied by NTT?
NTT's FLET'S Connection Tool PPPoE software is supplied in Japanese and may not work with some English-language operating systems. If you have installed some other PPPoE software to work in its place, it may be that the default settings of the PPPoE software you are using is not allowing full access to the Web.
In particular, the MTU (Maximum Transfer Unit) setting of non-NTT software may be set to 1490: whereas the suggested setting for NTT's FLET'S ADSL network is 1454. Please refer to the documentation supplied with the PPPoE software, or the Web page of the maker, to find out how to find and change this value. Users of NTT's FLET'S Connection Tool PPPoE software will not need to adjust the MTU value. Users of operating systems that have PPPoE integrated into the operating system, such as Windows XP and Mac OS X, will not need to make an adjustment to the MTU value.
4. Do you have more than one PPPoE software in your computer?
If you have installed more than one PPPoE software in your computer, you may find that they are incompatible and cause problems ranging from the inability of a connection to be established to a lack of Web access. It is suggested that you uninstall one of the PPPoE softwares. Users of operating systems that have PPPoE integrated into the operating system, such as Windows XP and Mac OS X, have no need to install other PPPoE software.
5. Are you using a Firewall?
Perhaps your firewall is configured in a way that is preventing access to some or all Web sites. If you are uncertain of how to adjust your firewall's settings, you may want to disable the firewall to test this out. If you find that Web pages appear after the firewall has been disabled, you will want to enable your firewall again and adjust its settings to allow you access to the Web sites you want to see.
