|
The GPRS Access Point Name specifying the APN used when establishing a data session with the GSM-based network. The APN often determines how the user will be billed for their network usage and whether the user has access to the Internet or just a provider-specific walled-garden, so it is important to use the correct APN for the user’s mobile broadband plan. The APN may only be composed of the characters a-z, 0-9, ., and - per GSM 03.60 Section 14.9. |

The configuration of the WiFi connection. Note the list of suboption attributes may vary depending on which version of NetworkManager/nmcli is installed on the host. An up-to-date list of supported attributes can be found here: https://networkmanager.dev/docs/api/latest/settings-802-11-wireless.html. For instance to create a hidden AP mode WiFi connection: |
|
Configures AP isolation, which prevents communication between wireless devices connected to this AP. This property can be set to a value different from If set to If set to When set to Choices:
Default: -1 |
|
The new field for the cloned MAC address. It can be either a hardware address in ASCII representation, or one of the special values This field replaces the deprecated cloned-mac-address on D-Bus, which can only contain explicit hardware addresses. Note that this property only exists in D-Bus API. libnm and nmcli continue to call this property cloned-mac-address. |
|
802.11 frequency band of the network. One of This will lock associations to the Wi-Fi network to the specific band, so for example, if This setting depends on specific driver capability and may not work with all drivers. Choices:
|
|
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. |
|
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. Default: 0 |
|
This D-Bus field is deprecated in favor of assigned-mac-address which is more flexible and allows specifying special variants like For libnm and nmcli, this field is called cloned-mac-address. |
|
With cloned-mac-address setting 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 If the value is still c(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 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 A value of If the value contains more than one additional MAC addresses, one of them is chosen randomly. For example, |
|
If 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. Choices:
|
|
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 (for example for MAC spoofing). |
|
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 (for example, |
|
One of This property is deprecated for cloned-mac-address. Choices:
Default: 0 |
|
Wi-Fi network mode. If blank, Choices:
|
|
If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple Ethernet frames. Default: 0 |
|
One of All other values are reserved. Choices:
Default: 0 |
|
If non-zero, directs the device to only use the specified bitrate for communication with the access point. Units are in Kb/s, so for example This property is highly driver dependent and not all devices support setting a static bitrate. Default: 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. Default: 0 |
|
The NMSettingWirelessWakeOnWLan options to enable. Not all devices support all options. May be any combination of Note the option values’ sum must be specified in order to combine multiple options. Default: 1 |
|
The security configuration of the WiFi connection. Note the list of suboption attributes may vary depending on which version of NetworkManager/nmcli is installed on the host. An up-to-date list of supported attributes can be found here: https://networkmanager.dev/docs/api/latest/settings-802-11-wireless-security.html. For instance to use common WPA-PSK auth with a password: |

|
|

Default: 0 |
|
List of strings specifying the allowed WPA protocol versions to use. Each element may be If not specified, both WPA and RSN connections are allowed. Choices:
|
|
Pre-Shared-Key for WPA networks. For WPA-PSK, it is either an ASCII passphrase of 8 to 63 characters that is (as specified in the 802.11i standard) hashed to derive the actual key, or the key in form of 64 hexadecimal character. The WPA3-Personal networks use a passphrase of any length for SAE authentication. |
|
Flags indicating how to handle the psk property. |
|
Flags indicating how to handle the wep-key0, wep-key1, wep-key2, and wep-key3 properties. |
|
Controls the interpretation of WEP keys. Allowed values are Choices:
|
|
Index 0 WEP key. This is the WEP key used in most networks. See the wep-key-type property for a description of how this key is interpreted. |
|
Index 1 WEP key. This WEP index is not used by most networks. See the wep-key-type property for a description of how this key is interpreted. |
|
Index 2 WEP key. This WEP index is not used by most networks. See the wep-key-type property for a description of how this key is interpreted. |
|
Index 3 WEP key. This WEP index is not used by most networks. See the wep-key-type property for a description of how this key is interpreted. |
|
When static WEP is used (that is, if key-mgmt=none) and a non-default WEP key index is used by the AP, put that WEP key index here. Valid values are Note that some consumer access points (like the Linksys WRT54G) number the keys Choices:
Default: 0 |
|
Flags indicating which mode of WPS is to be used if any. There is little point in changing the default setting as NetworkManager will automatically determine whether it is feasible to start WPS enrollment from the Access Point capabilities. WPS can be disabled by setting this property to a value of Default: 0 |
|
The trust level of the connection. When updating this property on a currently activated connection, the change takes effect immediately. |
