Random disconnects

[Nejc Škoberne]

  Hello,

I have UBNT NanoStation 2, which also uses wpa_supplicant. I set it up 
like this:

eapol_version=1
ap_scan=1
fast_reauth=1
network={
         ssid="eduroam"
         proto=RSN
         key_mgmt=WPA-EAP
         pairwise=CCMP
         scan_ssid=1
         bssid=00:17:DF:2C:xx:xx
         priority=1
         eap=TTLS
         identity="xxx"
         anonymous_identity="anonymous at xxx"
         password="xxx"
         phase2="auth=MSCHAPV2"
}

And this works. However, I get random disconnects:

1310857012.150280: CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys

The station then reconnects (sometimes it takes a few timeouts) and 
reauthenticates. What could be the problem? The signal level is about 
-81 dBi.

The whole debug log is here:
