Telkom Speedy On My Slackware

I am using slackware Linux and now I am home, In my home
I can not get 3G signal for my Indosat 3G broadband connection.
I just wondering why...., there is no 3G signal???

But fortunately, in my home I get Telkom Speedy connection here,
but my family always use MS Windows so i have to find how
telkom speedy concept and works.

And I realize that my Telkom Speedy uses PPPOE connection aka
Point to Point Protocol Over Ethernet Connection. So what this stuff means??

Wikipedia answer that PPPOE is a network protocol for encapsulating
Point-to-Point Protocol(PPP) frames inside Ethernet frames.

My Telkom Speedy network scheme is like below.

[Internet]<- Phone Line ->[Modem]<- Ethernet ->[Comp]

and PPPOE on ADSL diagrams (copied from Wikipedia) is below

Based on wikipedia definition and the scheme, I conclude that
PPPOE function for my network is to conveys communication
between ethernet [PC] and [PPP] Telkom speedy.

So, how do i build my connection on my Slackware box?
Previously I thought that I will face a complicated configuration
and process. But actually its just simple,you only need rp-pppoe  
and your speedy configuration such as speedy account,
speedy password, DNS Server.


The first step is install rp-pppoe on your system. And the do
pppoe-setup by typing

# pppoe-setup

and follow the instructions


So, you have configured your pppoe, and it you want to make 
connection you have to ensure that your eth0 or any network
interface doesnt connecto to your modem directly (has IP
in same network). To make connection you can do that by
typing:

# pppoe-start

and close connection by typing

# pppoe-stop

All of this command you must do those all in root mode.
