Researchers in Japan have developed an attack against WiFi Protected Access when using the Temporal Key Integrity Protocol (TKIP) that can successfully break the encryption in less than a minute. If you’re using WPA with TKIP, switch to AES, or step up to WPA2.
Or, be like me, and forget trying to encrypt your transmission method, and rely instead on strong encryption at the protocol level. All of the wireless networks I’ve set up at home have been wide open. If you’re not using SSL or TLS for your traffic anyway, you’re doing something wrong. Besides, I hate having to key in security details when I visit friends’ “protected” wireless networks.
