Hmm, so far I couldn't reproduce the problem when using WEP or no
encryption at all. I only see the disconnection when using
wpa_supplicant (WPA-PSK)...

From the APs view it looks as if the client just deauthenticates:

[...] hostapd: ath0: STA [...] IEEE 802.11: deauthenticated due to local deauth request
[...] hostapd: ath0: STA [...] IEEE 802.11: deassociated

My userland is older than the kernel; is this a possible reason for
the problem I'm seeing? I'll probably rebuild world and check again...


Regads, Jukka
