WEP is what encrypts all the wireless communications, not just what requires (and encrypts) login to the WLAN. So without WEP, all text sent is sent as clear text, including the non- trivial passwords, and is easily sniffable. Eg, just park on the street for a little while while the business is starting for the day and logging in, and there's all the passwords for you. Cf I had had the impression that Extreme's encryption was WAP, which is more secure than WEP, but don't see that in the Extreme tech specs pdf at http://docs.info.apple.com/article.html?artnum=75472.
