The NodeMCU WiFi control is spread across several tables:

- `wifi` for overall WiFi configuration
- [`wifi.sta`](#wifista-module) for station mode functions
- [`wifi.ap`](#wifiap-module) for wireless access point (WAP or simply AP) functions
- [`wifi.ap.dhcp`](#wifiapdhcp-module) for DHCP server control
- [`wifi.eventmon`](#wifieventmon-module) for wifi event monitor

## wifi.getchannel()

Gets the current WiFi channel.

#### Syntax
`wifi.getchannel()`

#### Parameters
`nil`

#### Returns
current WiFi channel

## wifi.getdefaultmode()

Gets default WiFi operation mode.

#### Syntax
`wifi.getdefaultmode()`

#### Parameters
`nil`

#### Returns
The WiFi mode, as one of the `wifi.STATION`, `wifi.SOFTAP`, `wifi.STATIONAP` or `wifi.NULLMODE` constants.

#### See also
[`wifi.getmode()`](#wifigetmode)
[`wifi.setmode()`](#wifisetmode)

## wifi.getmode()

Gets WiFi operation mode.

#### Syntax
`wifi.getmode()`

#### Parameters
`nil`

#### Returns
The WiFi mode, as one of the `wifi.STATION`, `wifi.SOFTAP`, `wifi.STATIONAP` or `wifi.NULLMODE` constants.

#### See also
[`wifi.getdefaultmode()`](#wifigetdefaultmode)
[`wifi.setmode()`](#wifisetmode)

## wifi.getphymode()

Gets WiFi physical mode.

#### Syntax
`wifi.getphymode()`

#### Parameters
none

#### Returns
The current physical mode as one of `wifi.PHYMODE_B`, `wifi.PHYMODE_G` or `wifi.PHYMODE_N`.

#### See also
[`wifi.setphymode()`](#wifisetphymode)

## wifi.resume()

Wake up WiFi from suspended state or cancel pending wifi suspension

#### Syntax
`wifi.resume([resume_cb])`

#### Parameters
- `resume_cb` Callback to execute when WiFi wakes from suspension. 
 !!! note "Note:"

    Any previously provided callbacks will be replaced!

#### Returns
`nil`

#### Example

```lua
--Resume wifi from timed or indefinite sleep
wifi.resume()

--Resume wifi from timed or indefinite sleep w/ resume callback
wifi.resume(function() print("WiFi resume") end)
```

#### See also
[`wifi.suspend()`](#wifisuspend)
[`node.sleep()`](node.md#nodesleep)
[`node.dsleep()`](node.md#nodedsleep)

## wifi.setmode()

Configures the WiFi mode to use. NodeMCU can run in one of four WiFi modes:

- Station mode, where the NodeMCU device joins an existing network
- Access point (AP) mode, where it creates its own network that others can join
- Station + AP mode, where it both creates its own network while at the same time being joined to another existing network
- WiFi off

When using the combined Station + AP mode, the same channel will be used for both networks as the radio can only listen on a single channel.

!!! note
	WiFi configuration will be retained until changed even if device is turned off.

#### Syntax
`wifi.setmode(mode[, save])`

#### Parameters
- `mode` value should be one of
	- `wifi.STATION` for when the device is connected to a WiFi router. This is often done to give the device access to the Internet.
	- `wifi.SOFTAP` for when the device is acting *only* as an access point. This will allow you to see the device in the list of WiFi networks (unless you hide the SSID, of course). In this mode your computer can connect to the device, creating a local area network. Unless you change the value, the NodeMCU device will be given a local IP address of 192.168.4.1 and assign your computer the next available IP address, such as 192.168.4.2.
	- `wifi.STATIONAP` is the combination of `wifi.STATION` and `wifi.SOFTAP`. It allows you to create a local WiFi connection *and* connect to another WiFi router.
	- `wifi.NULLMODE` changing WiFi mode to NULL_MODE will put wifi into a low power state similar to MODEM_SLEEP, provided `wifi.nullmodesleep(false)` has not been called.
- `save` choose whether or not to save wifi mode to flash
	- `true` WiFi mode configuration **will** be retained through power cycle. (Default)
	- `false` WiFi mode configuration **will not** be retained through power cycle.

#### Returns
current mode after setup

#### Example
```lua
wifi.setmode(wifi.STATION)
```

[`wifi.getdefaultmode()`](#wifigetdefaultmode)

## wifi.nullmodesleep()

Configures whether or not WiFi automatically goes to sleep in NULL_MODE. Enabled by default.

!!! note
	This function **does not** store it's setting in flash, if auto sleep in NULL_MODE is not desired, `wifi.nullmodesleep(false)` must be called after power-up, restart, or wake from deep sleep.

#### Syntax
`wifi.nullmodesleep([enable])`

#### Parameters
- `enable`
  - `true` Enable WiFi auto sleep in NULL_MODE. (Default setting)
  - `false` Disable WiFi auto sleep in NULL_MODE.

#### Returns
- `sleep_enabled` Current/New NULL_MODE sleep setting
	- If `wifi.nullmodesleep()` is called with no arguments, current setting is returned.
	- If `wifi.nullmodesleep()` is called with `enable` argument, confirmation of new setting is returned.

## wifi.startsmart()

Starts to auto configuration, if success set up SSID and password automatically.

Intended for use with SmartConfig apps, such as Espressif's [Android & iOS app](https://github.com/espressifapp).

Only usable in `wifi.STATION` mode.

!!! important

    SmartConfig is disabled by default and can be enabled by setting `WIFI_SMART_ENABLE` in [`user_config.h`](https://github.com/nodemcu/nodemcu-firmware/blob/dev/app/include/user_config.h#L96) before you build the firmware.

#### Syntax
`wifi.startsmart(type, callback)`

#### Parameters
- `type` 0 for ESP\_TOUCH, or 1 for AIR\_KISS.
- `callback` a callback function of the form `function(ssid, password) end` which gets called after configuration.

#### Returns
`nil`

#### Example

```lua
wifi.setmode(wifi.STATION)
wifi.startsmart(0,
	function(ssid, password)
		print(string.format("Success. SSID:%s ; PASSWORD:%s", ssid, password))
	end
)
```

#### Syntax
`wifi.stopsmart()`

#### Parameters

## wifi.suspend()

Suspend Wifi to reduce current consumption. 

This function is also useful for preventing WiFi stack related crashes when executing functions or tasks that take longer than ~500ms 

#### Syntax
`wifi.suspend({duration[, suspend_cb, resume_cb, preserve_mode]})`

#### Parameters
- `duration` Suspend duration in microseconds(μs). If a suspend duration of `0` is specified, suspension will be indefinite (Range: 0 or 50000 - 268435454 μs (0:4:28.000454))
- `suspend_cb` Callback to execute when WiFi is suspended. (Optional)
- `resume_cb` Callback to execute when WiFi wakes from suspension. (Optional)
- `preserve_mode` preserve current WiFi mode through node sleep. (Optional, Default: true)  
 - If true, Station and StationAP modes will automatically reconnect to previously configured Access Point when NodeMCU resumes.
 - If false, discard WiFi mode and leave NodeMCU in [`wifi.NULL_MODE`](#wifigetmode). WiFi mode will be restored to original mode on restart.

#### Returns
- `suspend_state` if no parameters are provided, current WiFi suspension state will be returned
 - States:
  - `0` WiFi is awake.
  - `1` WiFi suspension is pending. (Waiting for idle task)
  - `2` WiFi is suspended.


#### Example

```lua
--get current wifi suspension state
print(wifi.suspend())

--Suspend WiFi for 10 seconds with suspend/resume callbacks
 cfg={}
 cfg.duration=10*1000*1000
 cfg.resume_cb=function() print("WiFi resume") end
 cfg.suspend_cb=function() print("WiFi suspended") end

 wifi.suspend(cfg)

--Suspend WiFi for 10 seconds with suspend/resume callbacks and discard WiFi mode
 cfg={}
 cfg.duration=10*1000*1000
 cfg.resume_cb=function() print("WiFi resume") end
 cfg.suspend_cb=function() print("WiFfi suspended") end
 cfg.preserve_mode=false

#### Parameters
- `station_config` table containing configuration data for station
	- `ssid` string which is less than 32 bytes.
	- `pwd` string which is 0-64. Empty string indicates an open WiFi access point. _Note: WPA requires a minimum of 8-characters, but the ESP8266 can also connect to a WEP access point (a 40-bit WEP key can be provided as its corresponding 5-character ASCII string)._
	- `auto` defaults to true

		- The following formats are valid:
			- "DE:C1:A5:51:F1:ED"
			- "AC-1D-1C-B1-0B-22"
			- "DE AD BE EF 7A C0"
	- `save` Save station configuration to flash. 
		- `true` configuration **will** be retained through power cycle. 
		- `false` configuration **will not** be retained through power cycle. (Default)

#### Returns
- `true`  Success
- `false` Failure

#### Example

```lua
--connect to Access Point (DO NOT save config to flash)
station_cfg={}
station_cfg.ssid="NODE-AABBCC"
