You will need to reboot for the changes to take effect. Use a PPPOE Connection" Checkbox
"I use a PPPOE Connection" Checkbox
Checking this box lets XP Smoker know that you are using a PPPOE connection.
A PPPOE connection normally is a dialup or DSL connection that requires a username and password to log onto the network. It also requires a different MTU (Maximum Transmission Unit) for optimum performance, and in some cases to even work at all.
If you are unsure, I suggest calling your ISP support department first. They can tell you if your connection is a PPPOE connection.
If you check the box anyway and your connection is not a PPPOE connection it will not hurt it, however, it can degrade performance slightly.
Most Cable connections are not PPPOE.
Most DSL connections are PPPOE.
