•
MTU – Leave the Maximum Transmission Unit (MTU) at the
default value (1454) unless you have a particular reason to
change it.
•
Maximum Idle Time – Enter a maximum idle time (in minutes)
to define a maximum period of time for which the Internet
connection is maintained during inactivity (Default: 10). If the
connection is inactive for longer than the Maximum Idle Time,
it will be dropped. Enable the Auto-reconnect option to
automatically re-establish the connection as soon as you
attempt to access the Internet again.
•
Has your Internet Service Provider given you an IP address?
– If you are assigned a dynamic IP address every time you dial
up, select No for this item. However, if your ISP has assigned
a fixed IP address for you to use, select Yes for this item and
enter the IP address and subnet mask.
Note: If your ISP has given you a secondary phone number,
or if you have a secondary Internet service account,
then fill in the relevant fields under Secondary Dial-up.
