## Properties

Table 93.

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    assigned-mac-address
    string
| The new field for the cloned MAC address. It can be either a hardware address in ASCII representation, or one of the special values "preserve", "permanent", "random" or "stable". This field replaces the deprecated "cloned-mac-address" on D-Bus, which can only contain explict hardware addresses. Note that this property only exists in D-Bus API. libnm and nmcli continue to call this property "cloned-mac-address".
    band
    string
| 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.
    bssid
    byte array
| 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.
    channel
    uint32
    0
| 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.
    cloned-mac-address
    byte array
| This D-Bus field is deprecated in favor of "assigned-mac-address" which is more flexible and allows specifying special variants like "random". For libnm and nmcli, this field is called "cloned-mac-address".
    generate-mac-address-mask
    string
| 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.
    hidden
    boolean
    FALSE
| If TRUE, indicates this network is a non-broadcasting network that hides its SSID. In this case various workarounds may take place, such as probe-scanning the SSID for more reliable network discovery. However, these workarounds expose inherent insecurities with hidden SSID networks, and thus hidden SSID networks should be used with caution.
    mac-address
    byte array
| 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).
    mac-address-blacklist
    array of string
    []
| 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").
    mac-address-randomization
    uint32
    0
| One of NM_SETTING_MAC_RANDOMIZATION_DEFAULT (0) (never randomize unless the user has set a global default to randomize and the supplicant supports randomization), NM_SETTING_MAC_RANDOMIZATION_NEVER (1) (never randomize the MAC address), or NM_SETTING_MAC_RANDOMIZATION_ALWAYS (2) (always randomize the MAC address). This property is deprecated for 'cloned-mac-address'. Deprecated: 1
    mode
    string
| Wi-Fi network mode; one of "infrastructure", "adhoc" or "ap". If blank, infrastructure is assumed.
    mtu
    uint32
    0
| If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple Ethernet frames.
    name
    string
    802-11-wireless
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    powersave
    uint32
    0
| One of NM_SETTING_WIRELESS_POWERSAVE_DISABLE (2) (disable Wi-Fi power saving), NM_SETTING_WIRELESS_POWERSAVE_ENABLE (3) (enable Wi-Fi power saving), NM_SETTING_WIRELESS_POWERSAVE_IGNORE (1) (don't touch currently configure setting) or NM_SETTING_WIRELESS_POWERSAVE_DEFAULT (0) (use the globally configured value). All other values are reserved.
    rate
    uint32
    0
| 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.
    security
    None
| This property is deprecated, but can be set to the value '802-11-wireless-security' when a wireless security setting is also present in the connection dictionary, for compatibility with very old NetworkManager daemons.
    seen-bssids
    array of string
    []
| 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.
    ssid
    byte array
| SSID of the Wi-Fi network. Must be specified.
    tx-power
    uint32
    0
| 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.
