Without authentication
WPA authentication with WPA key. Enter the WPA key in ""WPA(2) Pass Phrase.
WPA authentication with RADIUS server. You configure the access data on the next
Basic Wizard page.
WPA2 authentication with WPA2 key. Enter the WPA2 key in ""WPA(2) Pass Phrase.
WPA2 authentication with RADIUS server. You configure the access data on the next
Basic Wizard page.
This authentication type is shown when iPCF, iPCF-HT or iPCF-MC mode is enabled
at the corresponding WLAN interface.
You can enable iPCF authentication in the "iFeatures (Page 404)" menu.
AES or TKIP is used depending on the capability of the other station.
A symmetrical encryption method with the RC4 algorithm (Ron's Code 4). In contrast
to the weak WEP encryption, TKIP uses changing keys derived from a main key. TKIP
can also recognize corrupted data frames.
Strong symmetrical block encryption method based on the Rijndael algorithm that
further improves the functions of TKIP.
