Bug ID: 213621
Summary: WIFI connection is lost periodically on ath0
Product: Base System
Version: 11.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: wireless

Hello.
Every several hours my wifi connection is lost. Removing tunnings from
sysctl.conf, tuning different setings on wifi router (disabling MAC Filtering,
chnging Beacon Interval/DTIM Interval/DHCP Address Lease Time/Group Key Update
Period) didn't help.
When connection is lost ifconfig shows nothing special, status stays
'associated'.
pinging shows following:
$ ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1): 56 data bytes
ping: sendto: Host is down

When I do 'reassociate' command inside wpa_cli shell connection restores. Also
it restores by running /etc/rc.d/netif restart.
Below is the listing from truss'ing wpa_supplicant service (first comes lines
when connection is lost, then I did reassociate):
