 Functions
 ---------
 
-.. function:: status()
+.. function:: mac([address])
 
-    Return the current status of the wireless connection.
+    Get or set the network interface's MAC address.
 
-    The possible statuses are defined as constants:
-
-        * ``STAT_IDLE`` -- no connection and no activity,
-        * ``STAT_CONNECTING`` -- connecting in progress,
-        * ``STAT_WRONG_PASSWORD`` -- failed due to incorrect password,
-        * ``STAT_NO_AP_FOUND`` -- failed because no access point replied,
-        * ``STAT_CONNECT_FAIL`` -- failed due to other problems,
-        * ``STAT_GOT_IP`` -- connection susccessful.
+    If the ``address`` parameter is provided, sets the address to its value. If
+    the function is called wihout parameters, returns the current address.

     called with two arguments, first being the hostname being resolved,
     second a tuple with information about that hostname.
 
+.. function:: wifi_mode([mode])
+
+    Get or set the wireless network operating mode.
+
+    If the ``mode`` parameter is provided, sets the mode to its value. If
+    the function is called wihout parameters, returns the current mode.
+
+    The possible modes are defined as constants:
+
+        * ``STA_MODE`` -- station mode,
+        * ``AP_MODE`` -- software access point mode,
+        * ``STA_AP_MODE`` -- mixed station and software access point mode.
+
+.. function:: phy_mode([mode])
+
+    Get or set the network interface mode.
+
+    If the ``mode`` parameter is provided, sets the mode to its value. If
+    the function is called wihout parameters, returns the current mode.
+
+    The possible modes are defined as constants:
+        * ``MODE_11B`` -- IEEE 802.11b,
+        * ``MODE_11G`` -- IEEE 802.11g,
+        * ``MODE_11N`` -- IEEE 802.11n.
+
+.. function:: sleep_type([sleep_type])
+
+    Get or set the sleep type.
+
+    If the ``sleep_type`` parameter is provided, sets the sleep type to its
+    value. If the function is called wihout parameters, returns the current
+    sleep type.
+
+    The possible sleep types are defined as constants:
+
+        * ``SLEEP_NONE`` -- all functions enabled,
+        * ``SLEEP_MODEM`` -- modem sleep, shuts down the WiFi Modem circuit.
+        * ``SLEEP_LIGHT`` -- light sleep, shuts down the WiFi Modem circuit
+          and suspends the processor periodically.
+
+    The system enters the set sleep mode automatically when possible.
+
+.. function:: deepsleep(time=0)
+
+    Enter deep sleep.
+
+    The whole module powers down, except for the RTC clock circuit, which can
+    be used to restart the module after the specified time if the pin 16 is
+    connected to the reset pin. Otherwise the module will sleep until manually
+    reset.
+
+.. function:: flash_id()
+
+    Read the device ID of the flash memory.
