Nl80211/cfg80211: add support for non EDCA based ranging measurement Add support for requesting that the ranging measurement will use the trigger-based / non. Cfg80211 — The configuration API for 802.11 devices in Linux. It works together with FullMAC drivers, which also should implement the MAC Sublayer Management Entity (MLME). Mac80211 — A subsystem of the Linux kernel that works with soft-MAC/half-MAC wireless devices. MLME is mostly implemented by the kernel, at least for station mode (STA).
Many of the times you may use a Linux system that does not have a GUI after install and it needs an internet connection to set up a desktop environment, also you may use Linux servers without a GUI and you need to connect over a wireless network using the command line. Below you will see Steps to connect to a wireless network using the command line.
Determine your Network Interface
The first thing you need to do is determining your Wireless Interface, to do so give the following command:
This will list out all the active network interfaces, most of the time it will be a wlan0 for your wireless network but can be something other, depending on your hardware.
Turn on your Wireless Interface
Now you need to ensure that your network interface is up and working, to do so give the following command.
wlan0 is your network interface, make sure you change it if your one is different.
Scan for available wireless access points
Now you will need to scan for all the available Access points, to do so give the following command
where more will help you get systematic scroll as the list could be long and you do not want that some entries disappear and you cannot scroll up as you are working in the command-line interface. Look at the ESSID, that is the name of your wireless network. To find an open network just check items that show Encryption Key set to off.
Create a WPA supplicant configuration file
The most common and widely tool used is WPA supplicant, most of the distros have it in default, just give the command
Now if you see any error you are in a deadlock situation as you cannot use this tool or it’s not installed. To create a configuration file for wpa_supplicant, run the following command:
Where ESSID will be your Access point name which you have noted from iwlist command, now after running the command your prompt is still not ended, now you need to type the security key of the Access point you need to connect to and press Enter and your prompt ends now.
After creating file check if the command worked, just give command:
Type the following:
and you should see something like below:
Find name of your wireless driver
Before proper connectivity there is more piece of information you will need which is the name of your driver of wireless network card, just give the command:
The command will list the section of drivers which will look like this:
Now, in this case, my appropriate driver is nl80211, this will be used in further connectivity.
Connect to the internet
The first step is to run the wpa_supplicant command :
sudo wpa_supplicant –B -D “driver” -i “interface” -c /etc/wpa_supplicant/wpa_supplicant.conf
where “driver” will be your driver(nl80211 in my case) without double quotes and “interface” will be your interface(wlan0 in my case) without double quotes.
Finally run the command:
This is for the DCHP client –dhclient– which will establish networking routing on the local Network. Now still to check connectivity you can just ping any website.

wiphy device needs to be suspended. The variable
wow
willbe NULL
or contain the enabled Wake-on-Wireless triggers that areconfigured for the device. wiphy device needs to be resumed
create a new virtual interface with the given name,must set the struct wireless_dev's iftype. Beware: You must createthe new netdev in the wiphy's network namespace! Returns the netdev,or an ERR_PTR.
remove the virtual interface determined by ifindex.
change type/configuration of virtual interface,keep the struct wireless_dev's iftype updated.
add a key with the given parameters.
mac_addr
will be NULL
when adding a group key. get information about the key with the given parameters.
mac_addr
will be NULL
when requesting information for a groupkey. All pointers given to the callback
function need not be validafter it returns. This function should return an error if it isnot possible to retrieve the key, -ENOENT if it doesn't exist. remove a key given the
mac_addr
(NULL
for a group key)and key_index
, return -ENOENT if the key doesn't exist. set the default key on an interface
set the default management frame key on an interface How to get i.l gross beat for mpc software for mac.
Add a beacon with given parameters,
head
, interval
and dtim_period
will be valid, tail
is optional. Change the beacon parameters for an access point modeinterface. This should reject the call when no beacon has beenconfigured.
Remove beacon configuration and stop sending the beacon.
Add a new station.
Remove a station;
mac
may be NULL to remove all stations. Modify a given station.
get station information for the station identified by

change a given mesh path
get a mesh path for the given parameters
dump mesh path callback -- resume dump at index

Get the current mesh configuration
Update mesh parameters on a running mesh.The mask is a bitfield which tells us which parameters toset, and which to leave alone.
join the mesh network with the specified parameters
leave the current mesh network
Modify parameters for a given BSS.
Set TX queue parameters
Set channel for a given wireless interface. Some devicesmay support multi-channel operation (by channel hopping) so cfg80211doesn't verify much. Note, however, that the passed netdev may be
NULL
as well if the user requested changing the channel for thedevice itself, or for a monitor interface. Request to do a scan. If returning zero, the scan request is giventhe driver, and will be valid until passed to
cfg80211_scan_done
.For scan results, call cfg80211_inform_bss
; you can call this outsidethe scan/scan_done bracket too. Request to authenticate with the specified peer
Request to (re)associate with the specified peer
Request to deauthenticate from the specified peer
Request to disassociate from the specified peer
Connect to the ESS with the specified parameters. When connected,call
cfg80211_connect_result
with status code WLAN_STATUS_SUCCESS
.If the connection fails for some reason, call cfg80211_connect_result
with the status from the AP. Disconnect from the BSS/ESS.
Join the specified IBSS (or create if necessary). Once done, call
cfg80211_ibss_joined
, also call that function when changing BSSID dueto a merge. Leave the IBSS.
Notify that wiphy parameters have changed;
changed
bitfield (see enum wiphy_params_flags) describes which valueshave changed. The actual parameter values are available instruct wiphy. If returning an error, no value should be changed. set the transmit power according to the parameters
store the current TX power into the dbm variable;return 0 if successful
set the WDS peer for a WDS interface
polls the hw rfkill line, use cfg80211 reportingfunctions to adjust rfkill hw state
run a test mode command
set the bitrate mask configuration
get site survey information.
Cache a PMKID for a BSSID. This is mostly useful for fullmacdevices running firmwares capable of generating the (re) associationRSN IE. It allows for faster roaming between WPA2 BSSIDs.
Delete a cached PMKID.
Flush all cached PMKIDs.
Request the driver to remain awake on the specifiedchannel for the specified duration to complete an off-channeloperation (e.g., public action frame exchange). When the driver isready on the requested channel, it must indicate this with an eventnotification by calling
cfg80211_ready_on_channel
. Cancel an on-going remain-on-channel operation.This allows the operation to be terminated prior to timeout based onthe duration value.
Transmit a management frame.
Cancel the wait time from transmitting a managementframe on another channel
Configure WLAN power management. A timeout value of -1allows the driver to adjust the dynamic ps timeout value.

Set antenna configuration (tx_ant, rx_ant) on the device.Parameters are bitmaps of allowed antennas to use for TX/RX. Drivers mayreject TX/RX mask combinations they cannot support by returning -EINVAL(also see nl80211.h
