Hi, all
I use NetworkManager's DSL to connect pppoe. pppoe can connect but disconnect when I open a page.
Any comment is very appreciated.

you have to change the mtu of eth0 to 1500
after successfully connecting with nm open a terminal
become root with su and execute the following command
ifconfig eth0 mtu 1500
