Conection to the internet through land line

Land line? oh i see... wired connection. It looks like there is a problem connecting with the LAN adaptor.
The Error code has to do with some problem connecting via wired connection.

Try pluging it off and on again while the system is off

Try connecting it with a different LAN cable

Try fine tune some settings on the Wii system options

Try connecting with an other LAN adaptor.

Make sure that the LAN adaptor you are using is made from Nintendo.
If still not working just call the local Nintendo Customer Service and report the problem.
