reset
#iwpriv ath
N
reset
This command will force a reset on the VAP and its underlying radio layer. Note that any VAP connected to
the same radio in mBSSID configuration will be affected. This is an action command that has no get command
or default value.
#iwpriv ath0 reset
roaming
#iwpriv ath
N
roaming
mode
The roaming mode defines how state transitions are controlled in the AP, and what will cause a scan to happen.
The roaming mode can take the following values:
Value
Definition
0
ROAMING_DEVICE. Scans are started in response to management frames coming in from the
WLAN interface, and the driver starts the scan without intervention
1
ROAMING_AUTO. Scan algorithm is controlled by the 802.11 layer in the AP. Similar to
ROAMING_DEVICE, additional algorithms are applied to the decision of when to
scan/reassociate/roam.
2
ROAMING_MANUAL: Roaming decisions will be driven by IOCTL calls by external applications,
such as the wpa_supplicant.
The default value is ROAMING_AUTO when in STA mode. This parameter has no meaning when operating
in AP mode. The command has a corresponding get command.

rssi11b
#iwpriv ath

rssi11g
These commands set the RSSI threshold for roaming in 11g and 11b modes. These thresholds are used to make
roaming decisions based on signal strength from the current set of APs available. The values are provided in
units of db. These commands have corresponding get commands. The default value for both is 24 dBm.

scanvalid
#iwpriv ath
N
scanvalid
period
This command sets the period that scan data is considered value for roaming purposes. If scan data is older than
this period, a scan will be forced to determine if roaming is required. The
period
is specified in seconds. This
command has a corresponding get command, and has a default value of 60 seconds.

setchanlist
getchanlist
This command is used by an application to set the channel list manually. Channels that are not valid from a
regulatory perspective will be ignored. This command is passed a byte array 255 bytes long that contains the
list of channels required. A value of 0 indicates “no channel”, but all 255 bytes must be provided. The
getchanlist will receive this array from the driver in a 255 byte array that contains the valid channel list. The
response is a binary array that WLAN tools cannot parse; therefore this cannot be used on the command line.
