The Economist writes about Wi-Fi and WEP: this article wisely focuses on the security problems inherent in the current revision of 802.11b and its standard implementation. Unfortunately, the writer produced this article almost literally a few days early: with Windows XP incorporating 802.1x support, the demand for this kind of authentication and encryption combo will grow rapidly. This in turn will encourage manufacturers to adopt it as a standard to support the tens of millions of XP users that will crop up this year.
The largest problem I see with the adoption of 802.1x lies in the small office/home office and individual user's experience and configuration. It's one thing for an office with information systems people to set up a RADIUS authentication server; it's another for the consumer who wants to experience the same confidence in their network's security. Ostensibly, Microsoft, Apple, and Linux vendors could bundle easily integratable RADIUS servers into their products tied in with the OS X, XP, 2000, and passwd user systems. We'll see.
