Hi, I’m new to opensuse.
I was trying to setup the pppoe connection to access to the internet in my house. I did setup the connection successfully, however, it just can’t connect to the network. 
Is it a bug?
Then, How can I connect to the internet?

chanyunkwan;
Can you ping Google? In a terminal window enter:
ping -c3 74.125.95.103
If the answer is yes see:

If the answer is no please post the results of:
ifconfig -a
/sbin/route -n
cat /etc/resolv.conf

Thanks for helping!! 
I can’t ping google~ It’s obvious that my laptop is not connecting to the internet at all.
I ran the commands and got these output.

Before you change this file manually, consider to define the
static DNS configuration using the following variables in the
/etc/sysconfig/network/config file:
NETCONFIG_DNS_STATIC_SEARCHLIST
NETCONFIG_DNS_STATIC_SERVERS
NETCONFIG_DNS_FORWARDER
or disable DNS configuration updates via netconfig by setting:
NETCONFIG_DNS_POLICY=’’
See also the netconfig(8) manual page and other documentation.
Note: Manual change of this file disables netconfig too, but
may get lost when this file contains comments or empty lines
only, the netconfig settings are same with settings in this
file and in case of a “netconfig update -f” call.
Please remove (at least) this line when you modify the file!
Then what’s next?
Thank you

Hello:
Large screen shots are not always helpful.
It looks like you have not configured your computer w/ administrator permissions. You will have to open yast w/ root password. Configure your network card w/ yast.
Next is the DSL(?) issues. You mentioned PPPoE. Is your outside connection a DSL? Yast also has a module to configure that.
On my own computers, I did not have to configure DSL. Once I set the interface cards, I got a connection, but, every setup is different. Every modem/service is different.
You will have to learn the command line interface. Open a console.
Go to (cd) /etc/sysconfig/network. “ls -la”
You should see a ifcfg listing for each device connected to this computer. “cat file_name” will show the contents.
Read. Learn. Eventually, you will start to understand something about what is going on.
The yast tool is not fool-proof. It has some problems. Once you have some understanding about what is going on, you can fix things from the console by changing text files.
I suggest you have pico. Try it. Very easy to use.
Good luck. Be aware that it takes awhile to understand to know what to ask. Everybody started dumb.
Thank you!
I figured that out a few days ago.
It’s because of knetworkmanager doesn’t work for DSL connection, though it provides DSL configuration interface.
I used YaST to switch to the traditional method to connect to the internet and use the DSL configuration in YaST. Then it works!
There’s also an alternative way, just remove the knetworkmanager and install the gnome networkmanager applet then run nm-applet. then I can connect to the dsl network by Gnome networkmanager applet which provides a very easy interface.
