Subject: Logs spammed by associate / authenticate / CRDA calls
Date: Mon, 17 Jan 2011 14:18:41 -0600 [thread overview]
Message-ID: <4D34A421.3070804@lwfinger.net> (raw)
I have just gotten the mac80211 code for the RTL8192CU devices for integration
into wireless-testing and then to mainline. All seems to be working, but I get a
lot of disassociation./reassociation messages followed by a call to CRDA. The
output from an 'iw event -t -f' command is the following:

1295294639.906219: wlan22 (phy #4): connected to c0:3f:0e:be:2b:45
The MAC address for the device is 00:1F:1F:C8:8E:CB and that of the AP is
C0:3F:0E:BE:2B:45, thus corresponding with the above output.
Is scanning this often normal? I suspect it is, but I have not looged the events
before.
Although both AP and STA support 802.11n, the connection is 802.11g (max 54
Mbps) using WPA2-PSK.
What triggers the "Disassociated due to inactivity"?
Thanks,
Larry
