Condition that can happen if connection cannot established:
1) Networkcard not detected........when you run netcard configuration (on knoppix menu), an error message will appear:
networkcard not detected or something.
2) Access concentration......when you run knoppix pppoe configuration (on knoppix menu), an error message will appear:
access concentration not found or something.

If you get error one or both.........your connection is failed.
If you don't get any error message, your connection is okay.....but you provided with wrong info.

I have read the sympatico manual on how to setup connection. There is nothing special need to be added, it's like other pppoe setup. You don't need sympatico pppoe utility.......you can use knoppix pppoe.

Step by step to setup your connection:
Go to bottom left, knoppix icon:

1)Networkcard configuration:
a)Click Network/Internet------>Network card configuration
b)Click no when asked if you want to use DHCP broadcast.
c)enter your netcard ip : 192.168.0.2
d)gateway : leave blank
e)broadcast ip : 192.168.0.255
f)DNS : (enter the dns provided by sympatico; some isp don't need this) Try this :198.235.216.130 and 198.235.216.131 or 4.2.2.1 and 4.2.2.2.

If above doesn't work......maybe your isp will assign you with ip. Choose to use DHCP broadcast.

2)PPPOE configuration
a)Click Network/Internet------>ADSL/PPPOE
b)Enter your username and password

Another way is.....run this command in your ms windows: ipconfig /all
Post it here, we will try to figure it out.

Good luck.
