>hi list, well, finally my ap works with wpa-eap, i use debian etch, madwifi-ng-r1475, freeradius 1.1.0 and hostapd 0.5.2. my ap can authenticate users and they can connect to wlan, everything ok.  but now result they cann't surf internet because connection is very slow, they cann't inclusive access google or yahoo, connection is too slow and requests are never completed or delays among 35-120 seconds.  i'm just performing tests, so ap and clients are in same room.
and when clients authenticating get lots of messages like this:

>so please could you help??? why clients connection is so slow?? by the way, my speed connection to internet in ap is very good. is there any parameter i should set to get clients could use internet without problems?? and why authentication delays to much too??.
i almost forget, if i turn off my ap and after turn it on, client cann't connect any more, it must be restarted to get connection again.
do you have any idea why this behavior??
