WEP is a deprecated and insecure standard that we do not support. It was superseded by WPA, in 2003 and in 2004, WPA2 became the IEEE compliant standard for Wi-Fi security. We fully support The WPA2 security standard and encourage you to use it.
LIFX Bulbs may work with WEP-128, but this is not supported. If you are having issues with connecting LIFX to your WEP network, please update your security settings to WPA/WPA2.
By switching from WEP to WPA2, you will gain a better experience with your LIFX Lights and more secure wireless network.
