This section includes properties relating to the operation of the interface and the associated radio.

PropertyDescription

antenna-gain (integer 0..30)

Overrides the default antenna gain. The master interface of each radio sets the antenna gain for every interface which uses the same radio.

This setting cannot override the antenna gain to be lower than the minimum antenna gain of a radio.
No default value.

beacon-interval (time interval 100ms..1s)

Interval between beacon frames of an AP. Default: 100ms.

Info

The 802.11 standard defines beacon interval in terms of time units (1 TU = 1.024 ms). The actual interval between beacons will be 1 TU for every 1 ms configured.

Note

Every AP running on the same radio (i.e. a master AP and all its 'virtual'/'slave' APs) must use the same beacon interval.

chains (list of integer 0..7 )

Radio chains to use for receiving signals. Defaults to all chains available to the corresponding radio hardware.

country (name of a country)

Determines, which regulatory domain restrictions are applied to an interface. Defaults to "Latvia".

Note

It is important to set this value correctly to comply with local regulations and ensure interoperability with other devices.

distance ()

Maximum link distance in kilometers, needs to be set for long-range outdoor links. The value should reflect the distance to the AP or station that is furthest from the device. Unconfigured value allows usage of 3KM links. 

Note

distance is not used by the wifi-qcom-ac package. Setting distance above the actual needed value can have detrimental effects on throughput and latency.

dtim-period (integer 1..255)

Period at which to transmit multicast traffic, when there are client devices in power save mode connected to the AP. Expressed as a multiple of the beacon interval.

Higher values enable client devices to save more energy, but increase network latency.

Default: 1

hide-ssid (no | yes)

  • yes - AP does not include its SSID in beacon frames, and does not reply to probe requests that have broadcast SSID.

  • no - AP includes its SSID in the beacon frames, and replies to probe requests that have broadcast SSID.

Default: no

manager (capsman |capsman-or-local | local)

capsman - the interface will act as CAP only, this option should not be passed via provisioning rules to the CAP

capsman-or-local - the interface will get configuration via CAPsMAN or use its own, if /interface/wifi/cap is not enabled.

local - interface won't contact CAPsMAN in order to get configuration.

Default: local

mode (ap | station)

Interface operation mode

  • ap (default) - interface operates as an access point
  • station - interface acts as a client device, scanning for access points advertising the configured SSID
  • station-bridge - interface acts as a client device and enables support for a 4-address frame format, so that the interface can be used as a bridge port
Info

The station-bridge mode, as implemented for 'wifi' intefaces, is incompatible with APs running the older 'wireless' package and vice versa.


multicast-enhance (enabled | disabled)

With the multicast-enhance feature enabled, an AP will convert every multicast-addressed IP or IPv6 packet into multiple unicast-addressed frames for each connected station.
This may improve link throughput and reliability since, unlike multicast frames, unicasts are acknowledged by stations and transmitted using a higher data rate.

Default: disabled

qos-classifier (dscp-high-3-bits | priority)
  • dscp-high-3-bits - interface will transmit data packets using a WMM priority equal to the value of the 3 most significant bits of the IP DSCP field
  • priority - interface will transmit data packets using a WMM priority equal to that set by IP firewall or bridge filter

Default: priority

Info

802.11ac wireless chipsets do not support the dscp-high-3-bits classifier mode. For 802.11ac interfaces, please see DSCP from priority.


ssid (string)The name of the wireless network, aka the (E)SSID. No default value.
tx-chains (list of integer 0..7)Radio chains to use for transmitting signals. Defaults to all chains available to the corresponding radio hardware.
tx-power (integer 0..40)A limit on the transmit power (in dBm) of the interface. Can not be used to set power above limits imposed by the regulatory profile. Unset by default.

Datapath properties

Parameters relating to forwarding packets to and from wireless client devices.
