The Modem will save the new settings and restart. Upon restarting the Modem will automatically establish the
WAN connection.
The following provides additional description of the settings for PPPoA and PPPoE connections:
PPPoA/PPPoE Parameters Description
User Name
For PPP connections, a User Name and Password are used to identify
and verify your account to the ISP. Enter the User Name for your ADSL
service account. User names and passwords are case-sensitive, so enter
this information exactly as given to you by your ISP.
Password
Together with the User Name, this is used to verify your account to the
ISP. Enter the Password exactly as given to you by your ISP.
AC Name
AC Name is optional for most users. Please contact your ISP if you are
uncertain whether an AC Name is required.
Service Name
Service Name is optional for most users. Please contact your ISP if you
are uncertain whether a Service Name is required.
Connection Type
This specifies the protocol (PPPoE or PPPoA) and the encapsulation
method (LLC or VC-MUX) used for your connection. The options
available are
PPPoE LLC, PPPoA LLC or PPPoA VC-Mux.
MTU
The Maximum Transmission Unit size may be changed if you want to
optimize efficiency for uploading data through the WAN interface. The
default setting (
1400 bytes) should be suitable for most users. Some
user may want to adjust the setting to optimize performance for wireless
traffic or when low latency is desired (such as with Internet gaming). It
is highly recommended that the user research how adjusting the MTU
may affect network traffic for better or worse.
MRU
Similar to the MTU, except this applies to Maximum Received Unit size
for downloading data. Most users will be happy with the default setting
(
1492 bytes). However this may also be optimized for fast downloads of
general bulk Internet traffic, for low latency or for downloading to
computers on the Wireless LAN. As with the MTU setting, the user
should carefully consider how changing the MRU may affect Internet
downloads for all systems on your LAN.
Default Route
When this is
Enabled, the Modem will be considered to be the primary
gateway to the Internet and WAN for systems on your network. If you
are using the Modem on a network with one or more alternative
gateway routers, you may prefer to disable this if you will use another
router as the primary gateway.
IP Control
This is used to determine how global IP settings are handled for the
WAN interface. Typically PPPoE or PPPoA connections will use the
default setting for
Dynamic IP. Some users will be given a specific IP
address for the WAN interface. In this case you need to change this
setting to
Static IP. When Static IP is selected in the IP Control drop-
down menu, you need to type in the global IP address provided to you
by your ISP.
Static IP
If you have selected the
Static IP option in the IP Control drop-down
menu, type in the global IP address used for your WAN interface. Your
ISP should provide this IP address to you.
Connection Setting
Select the desired option: Always ON, Connection On Demand, or
Manual. Most users will want to choose the default connection setting,
Always ON.
