WPA-PSK TKIP really not working with Ad-Hoc WLAN?

  1. Did I get it correctly that WPA-PSK TKIP encryption cannot be implemented in an
    Ad-Hoc WLAN? Open network works, WEP-encryption works, as soon as I try to use
    WPA (which works with these WLAN-cards when they are on a WLAN-router based
    network as clients) no connection is possible.

  2. Yes, the WiFi Alliance in its WPA and WPA2 certifications only supports TKIP
    encryption on infrastructure networks and not Ad-Hoc networks. Better
    encryption is coming through the IEEE's work in 802.11 based mesh networking
    (.11 working group "S"). Ad-hoc is currently only supported in an
    interoperable way for 802.11b and the set of MAC features that were defined
    at the time of its definition.

  3. Neither WPA-PSK nor WPA2-PSK, regardless of the encryption algorithm being
    TKIP or AES, is supported in XP in ad hoc mode.

    In Vista, WPA2-PSK with AES is supported in ad hoc mode. WPA2-PSK with TKIP
    and WPA-PSK with either TKIP or AES are not supported.
