Until now, French mac users had severe difficulties joining public wi-fi networks. Reason? For years, the Airport cards sold in France were limited to four channels. A restriction required by a local legislation (no longer active today; that's why it doesn't apply to AirPort Extreme cards).
Most of users thought the limitation was hardware. It was not! With the AirPort 3.3 update, all the channels are now available in the first generation cards. To check this:
- Update your Airport software
- Select "Create a Network" ("Créer un Réseau") from the AirPort menu
- Admire: now, all the channels are available to you.
This is not documented by Apple, so I thought your french readers would by interested to learn it.
Sorry for my bad english, I work hard to improve it ...
