Wi-Fi Settings

The “band” property

  “band”                     gchar *

802.11 frequency band of the network. One of "a" for 5GHz 802.11a or "bg" for 2.4GHz 802.11. This will lock associations to the Wi-Fi network to the specific band, i.e. if "a" is specified, the device will not associate with the same network in the 2.4GHz band even if the network's settings are compatible. This setting depends on specific driver capability and may not work with all drivers.

Flags: Read / Write

Default value: NULL

The “bssid” property

  “bssid”                    gchar *

If specified, directs the device to only associate with the given access point. This capability is highly driver dependent and not supported by all devices. Note: this property does not control the BSSID used when creating an Ad-Hoc network and is unlikely to in the future.

Flags: Read / Write

Default value: NULL

The “channel” property

  “channel”                  guint

Wireless channel to use for the Wi-Fi connection. The device will only join (or create for Ad-Hoc networks) a Wi-Fi network on the specified channel. Because channel numbers overlap between bands, this property also requires the "band" property to be set.

Flags: Read / Write / Construct

Default value: 0

The “cloned-mac-address” property

  “cloned-mac-address”       gchar *

If specified, request that the device use this MAC address instead. This is known as MAC cloning or spoofing.

Beside explicitly specifying a MAC address, the special values "preserve", "permanent", "random" and "stable" are supported. "preserve" means not to touch the MAC address on activation. "permanent" means to use the permanent hardware address of the device. "random" creates a random MAC address on each connect. "stable" creates a hashed MAC address based on connection.stable-id and a machine dependent key.

If unspecified, the value can be overwritten via global defaults, see manual of NetworkManager.conf. If still unspecified, it defaults to "preserve" (older versions of NetworkManager may use a different default value).

On D-Bus, this field is expressed as "assigned-mac-address" or the deprecated "cloned-mac-address".

Flags: Read / Write

Default value: NULL

The “generate-mac-address-mask” property

  “generate-mac-address-mask” gchar *

With “cloned-mac-address” setting "random" or "stable", by default all bits of the MAC address are scrambled and a locally-administered, unicast MAC address is created. This property allows to specify that certain bits are fixed. Note that the least significant bit of the first MAC address will always be unset to create a unicast MAC address.

If the property is NULL, it is eligible to be overwritten by a default connection setting. If the value is still NULL or an empty string, the default is to create a locally-administered, unicast MAC address.

If the value contains one MAC address, this address is used as mask. The set bits of the mask are to be filled with the current MAC address of the device, while the unset bits are subject to randomization. Setting "FE:FF:FF:00:00:00" means to preserve the OUI of the current MAC address and only randomize the lower 3 bytes using the "random" or "stable" algorithm.

If the value contains one additional MAC address after the mask, this address is used instead of the current MAC address to fill the bits that shall not be randomized. For example, a value of "FE:FF:FF:00:00:00 68:F7:28:00:00:00" will set the OUI of the MAC address to 68:F7:28, while the lower bits are randomized. A value of "02:00:00:00:00:00 00:00:00:00:00:00" will create a fully scrambled globally-administered, burned-in MAC address.

If the value contains more than one additional MAC addresses, one of them is chosen randomly. For example, "02:00:00:00:00:00 00:00:00:00:00:00 02:00:00:00:00:00" will create a fully scrambled MAC address, randomly locally or globally administered.

Flags: Read / Write

Default value: NULL

The “hidden” property

  “hidden”                   gboolean

If TRUE, indicates that the network is a non-broadcasting network that hides its SSID. This works both in infrastructure and AP mode.

In infrastructure mode, various workarounds are used for a more reliable discovery of hidden networks, such as probe-scanning the SSID. However, these workarounds expose inherent insecurities with hidden SSID networks, and thus hidden SSID networks should be used with caution.

In AP mode, the created network does not broadcast its SSID.

Note that marking the network as hidden may be a privacy issue for you (in infrastructure mode) or client stations (in AP mode), as the explicit probe-scans are distinctly recognizable on the air.

Flags: Read / Write

Default value: FALSE

The “mac-address” property

  “mac-address”              gchar *

If specified, this connection will only apply to the Wi-Fi device whose permanent MAC address matches. This property does not change the MAC address of the device (i.e. MAC spoofing).

Flags: Read / Write

Default value: NULL

The “mac-address-blacklist” property

  “mac-address-blacklist”    GStrv

A list of permanent MAC addresses of Wi-Fi devices to which this connection should never apply. Each MAC address should be given in the standard hex-digits-and-colons notation (eg "00:11:22:33:44:55").

Flags: Read / Write

The “mac-address-randomization” property

  “mac-address-randomization” guint

One of NM_SETTING_MAC_RANDOMIZATION_DEFAULT (never randomize unless the user has set a global default to randomize and the supplicant supports randomization), NM_SETTING_MAC_RANDOMIZATION_NEVER (never randomize the MAC address), or NM_SETTING_MAC_RANDOMIZATION_ALWAYS (always randomize the MAC address). This property is deprecated for 'cloned-mac-address'.

Flags: Read / Write

Default value: 0

Since: 1.2

The “mode” property

  “mode”                     gchar *

Wi-Fi network mode; one of "infrastructure", "adhoc" or "ap". If blank, infrastructure is assumed.

Flags: Read / Write

Default value: NULL

The “mtu” property

  “mtu”                      guint

If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple Ethernet frames.

Flags: Read / Write / Construct

Default value: 0

The “powersave” property

  “powersave”                guint

One of NM_SETTING_WIRELESS_POWERSAVE_DISABLE (disable Wi-Fi power saving), NM_SETTING_WIRELESS_POWERSAVE_ENABLE (enable Wi-Fi power saving), NM_SETTING_WIRELESS_POWERSAVE_IGNORE (don't touch currently configure setting) or NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (use the globally configured value). All other values are reserved.

Flags: Read / Write

Default value: 0

Since: 1.2

The “rate” property

  “rate”                     guint

If non-zero, directs the device to only use the specified bitrate for communication with the access point. Units are in Kb/s, ie 5500 = 5.5 Mbit/s. This property is highly driver dependent and not all devices support setting a static bitrate.

Flags: Read / Write / Construct

Default value: 0

The “seen-bssids” property

  “seen-bssids”              GStrv

A list of BSSIDs (each BSSID formatted as a MAC address like "00:11:22:33:44:55") that have been detected as part of the Wi-Fi network. NetworkManager internally tracks previously seen BSSIDs. The property is only meant for reading and reflects the BSSID list of NetworkManager. The changes you make to this property will not be preserved.

Flags: Read / Write

The “ssid” property

  “ssid”                     GBytes *

SSID of the Wi-Fi network. Must be specified.

Flags: Read / Write

The “tx-power” property

  “tx-power”                 guint

If non-zero, directs the device to use the specified transmit power. Units are dBm. This property is highly driver dependent and not all devices support setting a static transmit power.

Flags: Read / Write / Construct

Default value: 0

The “wake-on-wlan” property

  “wake-on-wlan”             guint

The NMSettingWirelessWakeOnWLan options to enable. Not all devices support all options. May be any combination of NM_SETTING_WIRELESS_WAKE_ON_WLAN_ANY, NM_SETTING_WIRELESS_WAKE_ON_WLAN_DISCONNECT, NM_SETTING_WIRELESS_WAKE_ON_WLAN_MAGIC, NM_SETTING_WIRELESS_WAKE_ON_WLAN_GTK_REKEY_FAILURE, NM_SETTING_WIRELESS_WAKE_ON_WLAN_EAP_IDENTITY_REQUEST, NM_SETTING_WIRELESS_WAKE_ON_WLAN_4WAY_HANDSHAKE, NM_SETTING_WIRELESS_WAKE_ON_WLAN_RFKILL_RELEASE, NM_SETTING_WIRELESS_WAKE_ON_WLAN_TCP or the special values NM_SETTING_WIRELESS_WAKE_ON_WLAN_DEFAULT (to use global settings) and NM_SETTING_WIRELESS_WAKE_ON_WLAN_IGNORE (to disable management of Wake-on-LAN in NetworkManager).

Flags: Read / Write / Construct

Default value: 1
