## Property Details

### The `"band"` property

      "band"                     gchar*                : Read / Write

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 WiFi 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.

Default value: NULL

### The `"bssid"` property

      "bssid"                    GArray_guchar_*       : Read / Write

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.

### The `"channel"` property

      "channel"                  guint                 : Read / Write / Construct

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

Default value: 0

### The `"cloned-mac-address"` property

      "cloned-mac-address"       GArray_guchar_*       : Read / Write

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

### The `"hidden"` property

      "hidden"                   gboolean              : Read / Write

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.

Default value: FALSE

### The `"mac-address"` property

      "mac-address"              GArray_guchar_*       : Read / Write

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

### The `"mac-address-blacklist"` property

      "mac-address-blacklist"    GSList_gchararray_*   : Read / Write

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').

### The `"mode"` property

      "mode"                     gchar*                : Read / Write

WiFi network mode; one of 'infrastructure', 'adhoc' or 'ap'. If blank, infrastructure is assumed.

Default value: NULL

### The `"mtu"` property

      "mtu"                      guint                 : Read / Write / Construct

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

Default value: 0

### The `"rate"` property

      "rate"                     guint                 : Read / Write / Construct

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.

Default value: 0

### The `"security"` property

      "security"                 gchar*                : Read / Write

If the wireless connection has any security restrictions, like 802.1x, WEP, or WPA, set this property to '802-11-wireless-security' and ensure the connection contains a valid 802-11-wireless-security setting.

Default value: NULL

### The `"seen-bssids"` property

      "seen-bssids"              GSList_gchararray_*   : Read / Write

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 BBSID list of NetworkManager. The changes you make to this property will not be preserved.

### The `"ssid"` property

      "ssid"                     GArray_guchar_*       : Read / Write

SSID of the WiFi network.
