European Wifi...any different than US Wifi??

Hi, I'm going to Paris & London next week. I have a Macbook Air...do I need to adjust the wifi setting or change anything in order to pick up wifi in europe??? I heard european wifi is a little different.

Some countries allow more channels for wifi (e.g. US goes from channel 1 to 11, Japan goes from 1 to 13).

You shouldn't need to change anything to get your macbook air to work. I didn't have any problem in Europe with my laptop.

You don't need to change it as I used my laptop in USA and UK and I didn't change any thing for working well.
