Hola a tod@s:
Estoy en un nuevo proyecto que emplea wifi y datos del movil, y tenia que estar empleando varias librerias para poder hacer varias cosas con respecto a este tema.
Pensaba hacer una libreria, pero al ver que un compañero del foro inglés (Jem Miller) habia dejado de actualizar una suya y dejaba los fuentes, me decidí a añadir los métodos que necesitaba y de esa forma he eliminado librerias y he puesto esta.
He modificado el código fuente, he corregido algunos errores y agregado nuevos métodos que necesitaba.
He probado en Android 4x, 5x y 6x en diferentes dispositivos y no me da ningún error.
Os paso las características, perdonar que sean en inglés, pero no tengo mucho tiempo y lo que hice es copiar los comentarios que puse en los métodos, eventos, etc

Constants:
WIFI_2_4GHZ_BAND As Int = 1
2.4GHz WIFI Band
WIFI_5GHZ_BAND As Int = 2
5GHz WIFI Band
WIFI_MODE_FULL As Int = 1
In this WIFI lock mode, WIFI will be kept active, and will behave normally. It will attempt to automatically establish a connection to a remembered access point that is within range, and will do periodic scans if there are remembered access points but none are in range.
WIFI_MODE_SCAN_ONLY As Int = 2
In this WIFI lock mode, WIFI will be kept active, but the only operation that will be supported is initiation of scans, and the subsequent reporting of scan results. No attempts will be made to automatically connect to remembered access points, nor will periodic scans be automatically performed looking for remembered access points.
Scans must be explicitly requested by an application in this mode.
WIFI_MODE_FULL_HIGH_PERF As Int = 3
In this WIFI lock mode, WIFI will be kept active as in mode WIFI_MODE_FULL but it operates at high performance with minimum packet loss and low packet latency even when the device screen is off.
This mode will consume more power and hence should be used only when there is a need for such an active connection.

saveWifiAP(String ssid, int security, String password, boolean connect) As Boolean
Saves the configuration of a WIFI AP onto the device
ssid: Access Point SSID
security: Access Point security type (0:NONE, 1:WEP, 2:WAP)
password: Access Point password/phrase ("" for an open network)
connect: true -> Connect to the WIFI AP after saving
Returns True on success
isSavedWifiAP(String ssid) As Boolean
Checks if a WIFI AP is saved on the device
ssid: Access Point SSID
Returns True if this SSID is saved
removeWifiAP(String ssid) As Boolean
Remove a saved WIFI AP on the device
ssid: Access Point SSID
Returns True on success
disconnectWifiAP() As Boolean
Disconnects the current WIFI AP connection

Class MLscan
Events:
ScanDone(Results() As String, Count As Int)
Launches when Scan finishes and a new list of Access Points is ready
Results(): A string array containing all scanned Access Points in the area of the device.
These are comma separated entries consisting of the following:
SSID, Security Type, Signal strength, and "Saved" if this network was previously
saved for use on this device.
Count: The number of elements in the Results() array
Fields:
wifis As String()
A string array containing all scanned Access Points in the area of the device.
These are comma separated entries consisting of the following:
SSID, Security Type, Signal strength, and "Saved" if this network was previously
saved for use on this device.
Methods:
startScan(EventName As String)
Initializes all objects and scans for WIFI networks. Builds a string array
of results (wifis) that can be accessed directly or with a call to updateWifiList.
EventName: Name of the Event to launch when Scan finish (EventName_ScanDone)
THIS METHOD SHOULD ONLY BE CALLED ONCE!
Call only after startScan has already been called and a string array of Access Points
has been built. This method returns a string array containing the access points from the
most recent scan, including background scans done automatically by the Android WifiManager.
Calls the ScanDone event when a new list is ready.
Returns the string array of comma separated WIFI access points by SSID. Each entry may
contain the following:
SSID, Security Type, Signal level (in dBm), and the word "Saved" if the network was
previously saved for use on this device.
updateWifiList
getBSSID(EntryNumber As Int) As String
Returns the BSSID for the selected entry.
EntryNumber: If you display the string array wifis or the array returned in the getWifiList method UNSORTED,
you can pass the Position variable from your ListView_Click event.
Otherwise, you must pass the entry number from the string array since that is what is used as a reference.
WifiCap(EntryNumber As Int) As String
Returns a String containing info about the selected entry. A startScan must have already been done.
The string contains the SSID, the BSSID, and the Capabilities of the Network Access Point,
comma separated (SSID,BSSID,CapabilityString). The capabilities part can be quite long.
EntryNumber: If you display the string array wifis or the array returned in the getWifiList method UNSORTED,
you can pass the Position variable from your ListView_Click event.
Otherwise, you must pass the entry number from the string array since that is what is used as a reference.
Returns a string of comma separated entries of SSID,BSSID, and capability string. Returns an empty string on error.
isSavedWifiAP(EntryNumber As Int) As Boolean
Checks the stored networks on the device to see if this entry is a previously saved Access Point
EntryNumber: The entry number in the wifis array to check. If you display the string array wifis or
the array returned in the getWifiList method UNSORTED, you can pass the Position variable from
your ListView_Click event.
Otherwise, you must pass the entry number from the string array since that is what is used as a reference.
Returns True if this is a stored network
connectWifiAP(EntryNumber As Int) As Boolean
Connects to a network already configured on the device. The device will use saved values to connect.
EntryNumber: If you display the string array wifis or the array returned in the getWifiList method UNSORTED,
you can pass the Position variable from your ListView_Click event.
Otherwise, you must pass the entry number from the string array since that is what is used as a reference.
Returns true on success
listSavedNetworks As List
Builds a list of all saved networks on the device.
Returns a comma separated list of: SSID,BSSID,Network ID number.
saveWifiAP(EntryNumber As Intr, securityType As String, Password As String) As Boolean
Saves the configuration of a WIFI AP onto the device and connects to it.
EntryNumber: If you display the string array wifis or the array returned in the getWifiList method UNSORTED,
you can pass the Position variable from your ListView_Click event.
Otherwise, you must pass the entry number from the string array since that is what is used as a reference.
securityType: The Access Point security type (returned in the scan result string array)
Password: The password/phrase for the WIFI access point. Pass "" for an open network. Handles WEP HEX or text phrases
Returns True if the connection is successful
removeWifiAP(NetId As Int) As Boolean
Remove a saved WIFI AP on the device
NetId - The network ID number to delete (returned in the listSavedNetworks method)
Returns True on success
