help with opera nintendo DS

Hi,

I can't get the opera browser to work with the DS lite.
Just trying to get it to surf the net, not really to play games.
Shouldn't it just hook up at Krystal's or MacDonald's no prob?
It did not work either place.

Has anyone tried it just for browsing? I tried it at one place
and it said 'error 51300' but I think that place had a log in
screen which the DS does not like.

thx
