WiFi Options ​

Configuration for each radio device is calculated from

  • the general options in config lime wifi
  • the corresponding band specific section for 2ghz and 5ghz also included in lime-defaults
  • an (optional) interface specific section relative to that specific radio device.

General options ​

Settings in the section config lime wifi applies to all radios.

The LibreMesh configurations in the sections wifi lime-wifi-band and specific radioN contains options for configuring:

  • radio device options like channel, distance, htmode and txpower
  • wifi interfaces options for Access Points, like ap_ssid, ap_key, ap_encryption, or other supported modes like 80211s or client.
  • network options, protocols list and options are inherited from the default network section config lime 'network'

ap_ssid ​

  • Type: string
  • Default: LibreMesh.org
config lime wifi
	option ap_ssid 'LibreMesh.org'

Set here your network name, this value is required even if AP is not used, as it is used for calculating fields with %Nn.

country ​

  • Type: country code
  • Default: unset, uses default 00 (World)

Set this to your location country code, for example in Spain, setting ES allows you to use channel 13

modes ​

  • adhoc - See below for adhoc configuration
  • ap - This mode setup an Access Point, with the same ssid in each node for roaming purposes.
  • apbb - Backbone AP, for other LibreMesh routers connection rather than for users connectio
  • apname - This mode setup an Access Point, with specific ssid for each node.
  • apup - This mode setup radio for APuP operation.
  • client - client configuration should be done in Wifi specific options
  • ieee80211s - Used for mesh links between nodes.

modes options ​

See the next page Wifi Modes for details on Access Points, Adhoc, APuP and 802.11s options.

Workaround for deaf radios ​

ath9k warning

Routers with Atheros radios and the ath9k driver have a known bug that cause them to become deaf, if you are using an OpenWrt older than 24.10.6 be sure to include the libremesh package wifi-unstuck-wa

unstuck_interval ​

  • Default: 10
  • Packages required: wifi-unstuck-wa
config lime 'wifi'
    option unstuck_interval '10'

Interval in minutes that defines how often to run the workaround script provided by the package wifi-unstuck-wa that rescan all available frequencies in active radios.

unstuck_timeout ​

  • Default: 10
  • Packages required: wifi-unstuck-wa
config lime 'wifi'
    option unstuck_interval '10'

Timeout in seconds that defines how long the mentioned above workaround should go.
