¿Cómo puedo recuperar la intensidad de señal de las redes LAN inalámbricas cercanas en Windows utilizando Python?¿Cómo puedo recuperar la potencia de señal de las redes LAN inalámbricas cercanas en Windows usando Python?
Me gustaría mostrar o graficar los valores.
Si usted está en de Windows, es probable que quieren utilizar la API de WLAN, que proporciona la función 'WlanGetAvailableNetworkList()' (ver el API docs para el uso). No conozco ninguna envoltura de Python para WLANAPI.DLL, por lo que es posible que deba envolverla usted mismo usando ctypes. Tengo un script preliminar que hace esto (works-for-me), pero puede ser complicado. Usted querrá leer la documentación para entender el significado de todos los campos:

En Linux, usted tiene un par de opciones:
Las opciones estándar consiste en analizar la salida de iwlist -scan . Sin embargo, si actualmente está conectado a un wlan y no se ejecuta como root, solo devuelve el wlan actualmente conectado.
Si necesita más que esto, la mejor manera es consultar el daemon del administrador inalámbrico. En los modernos, linux, generalmente es NetworkManager, aunque wicd es cada vez más popular. Ambos gerentes pueden ser consultados usando dbus. A menos que pueda controlar lo que los clientes tienen en sus sistemas, es posible que deba admitir estas dos opciones, o al menos una opción, y tener un respaldo para iwlist.
Bien podría invocar el comando del sistema para obtener esa información (Linux = iwlist), analizar el resultado y visualizarlo.
@fmark Solo quería decir GRACIAS por esta increíble publicación. En mi trabajo, he intentado obtener RSSI del AP conectado en Windows, y mereces muchas gracias por haberlo logrado finalmente. Actualmente estoy enumerando todos los AP, pero estoy trabajando para modificarlo. Quería ofrecer una recomendación para tu código. No tengo mucha experiencia con C o el módulo Python CTypes, pero creo que podría haber encontrado un posible error. Realmente no estoy seguro de lo que hace la diferencia, pero me di cuenta:
enumeraciones se definen así:
DOT11_BSS_TYPE = c_uint
(dot11_BSS_type_infrastructure,
dot11_BSS_type_independent,
dot11_BSS_type_any) = map(DOT11_BSS_TYPE, xrange(1, 4))
Pero otras veces se define algo muy similar como esto:
DOT11_PHY_TYPE = c_uint
dot11_phy_type_unknown = 0
dot11_phy_type_any = 0
dot11_phy_type_fhss = 1
dot11_phy_type_dsss = 2
dot11_phy_type_irbaseband = 3
dot11_phy_type_ofdm = 4
dot11_phy_type_hrdsss = 5
dot11_phy_type_erp = 6
dot11_phy_type_ht = 7
dot11_phy_type_IHV_start = 0x80000000
dot11_phy_type_IHV_end = 0xffffffff
Creo que el segundo snippit debería modelarse como el primero, pero podría estar equivocado. Aquí estaba mi idea:
DOT11_PHY_TYPE = c_uint
(dot11_phy_type_unknown,
dot11_phy_type_any,
dot11_phy_type_fhss,
dot11_phy_type_dsss,
dot11_phy_type_irbaseband,
dot11_phy_type_ofdm,
dot11_phy_type_hrdsss,
dot11_phy_type_erp,
dot11_phy_type_ht,
dot11_phy_type_IHV_start,
dot11_phy_type_IHV_end) = map(DOT11_PHY_TYPE,
[0,0,1,2,3,4,
5,6,7,0x80000000,
0xffffffff])
De esta manera, esos valores se asignarían correctamente a DOT11_PHY_TYPE. Quizás estoy completamente equivocado, pero para las personas futuras como yo, simplemente quería que todo lo que se topara aquí sea correcto :) Gracias de nuevo, @fmark.
Así que ... me basé en el código @fmarks (que era más seguro para mí), y debe agregar la función WlanScan , o los valores RSSI no actualizarán.
¡Aquí está mi código extendido!
Todos los accesorios para @fmarks!

Si no quiere tratar con la API de Windows se puede utilizar el método mostrado here con una ligera modificación.
Usted puede utilizar este comando:
netsh wlan show networks mode=Bssid
utilizando este código
import subprocess
results = subprocess.check_output(["netsh", "wlan", "show", "network", "mode=Bssid"])
Esto le dará la información additiona "señal" como un porcentaje. Esto se puede convertir a RSSI usando this method.
