Wie kann ich mithilfe von Python die Signalstärke naher WLAN-Netzwerke unter Windows abrufen?Wie kann ich mithilfe von Python die Signalstärke naher WLAN-Netzwerke unter Windows abrufen?
Ich möchte die Werte entweder anzeigen oder grafisch darstellen.
Wenn Sie auf Windows-, möchten Sie wahrscheinlich zu die WLAN-API verwenden, die die 'WlanGetAvailableNetworkList()' Funktion liefert (siehe API docs für Nutzung). Mir sind keine Python-Wrapper für WLANAPI.DLL bekannt, sodass Sie sie möglicherweise selbst verpacken müssen, indem Sie ctypes verwenden. Ich habe ein vorläufiges Skript, das dies tut (funktioniert für mich), aber es kann knifflig sein. Sie finden die Dokumentation lesen wollen, die Bedeutung aller Felder zu verstehen:

Auf Linux, Sie haben ein paar Möglichkeiten:
Die Standard-Optionen ist die Ausgabe von iwlist -scan zu analysieren . Wenn Sie jedoch derzeit mit einem Wlan verbunden sind und nicht als root ausgeführt werden, wird nur der aktuell verbundene Wlan zurückgegeben.
Wenn Sie mehr als das benötigen, ist der beste Weg, den Wireless Manager Daemon abzufragen. Auf modernen Linux ist dies normalerweise NetworkManager, obwohl wicd immer beliebter wird. Beide Manager können mit dbus abgefragt werden. Wenn Sie nicht kontrollieren können, was die Clients auf ihren Systemen haben, müssen Sie möglicherweise beide Optionen oder mindestens eine Option unterstützen und einen Fallback für iwlist haben.
Nun, Sie könnten den Systembefehl aufrufen, um diese Informationen zu erhalten (Linux = iwlist), das Ergebnis analysieren und anzeigen.
@fmark Ich wollte nur sagen, DANKE so viel für diesen tollen Beitrag. Bei meiner Arbeit habe ich versucht, RSSI von dem verbundenen AP in Windows zu erhalten, und Sie verdienen vielen Dank, dass ich es endlich geschafft habe. Ich lese derzeit alle APs, aber ich arbeite daran, sie zu ändern. Ich wollte eine Empfehlung zu Ihrem Code abgeben. Ich bin nicht sehr erfahren mit C oder dem Python CTypes Modul, aber ich denke, dass ich einen möglichen Fehler gefunden habe. Ich bin wirklich nicht sicher, was für einen Unterschied es macht, aber ich merkte:
Sie definieren Aufzählungen wie folgt aus:
DOT11_BSS_TYPE = c_uint
(dot11_BSS_type_infrastructure,
dot11_BSS_type_independent,
dot11_BSS_type_any) = map(DOT11_BSS_TYPE, xrange(1, 4))
Aber dann andere Zeiten, die Sie definieren etwas sehr ähnlich wie folgt aus:
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
Ich denke, der zweite Snippit sollte wie der erste aussehen, aber ich könnte falsch liegen. Hier war meine Idee:
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])
Auf diese Weise würden diese Werte korrekt auf DOT11_PHY_TYPE zugeordnet werden. Vielleicht bin ich völlig falsch, aber für zukünftige Leute wie mich, wollte ich nur, was hier richtig gestolpert ist :) Nochmals vielen Dank, @fmark.
Also .. Ich stützte mich auf @fmarks-Code (der war ein Live-sicherer für mich), und Sie sollten die WlanScan-Funktion hinzufügen, sonst die RSSI-Werte nicht aktualisieren.
Hier ist mein erweiterter Code!
Alle Requisiten zu @fmarks!

Wenn Sie nicht mit Windows-API beschäftigen möchten Sie Methode here mit einer geringfügigen Änderung gezeigt verwenden könnte.
können Sie diesen Befehl verwenden: Diese
import subprocess
results = subprocess.check_output(["netsh", "wlan", "show", "network", "mode=Bssid"])
geben Ihnen additiona "Signal" Informationen als Prozentsatz
netsh wlan show networks mode=Bssid
diesen Code verwenden. Dies kann mit this method in RSSI konvertiert werden.
Bitte geben Sie Ihre Plattform an (Windows, Linux, ...) – ChristopheD
Ich verwende Windows. – kame
