At least you can reconnect ;-) That didn't used to be possible
I'm at lounge 25 right now (Sunday morning 7am) and the new Schiphol network works quite well. It offers about 50KB/sec speeds. I did notice the terms though, where it advertises a paid option which is
not ad supported. That implies that the free version
is ad supported.
How does one show ads using a wifi network? Exactly, by replacing legitimate ads on websites. Which is the sole income for many websites. I do not have proof that they actually do this, but it is implied. And if they do it's very, very wrong.
