LANCOM OAP-54-1 Wireless – LANCOM OAC-54-1 Wireless The passphrases for 802.11i or WPA do not have to be changed quite so regularly as new keys are generated for each connection anyway. This is not the only reason that the encryption with 802.11i/AES or WPA/TKIP is so much more secure than the now obsolete WEP method. If you use WEP encryption to maintain compatibility with older WLAN clients, regularly change the WEP key in your access point.
LANCOM OAP-54-1 Wireless – LANCOM OAC-54-1 Wireless Chapter 4: Security settings third-party products is assured as LEPS only involves configuration in the access point.
