如何使用python查找并连接所有可用的wifi信号？

Question

I am working raspberry pi to find and connect all available wifi connections. How can I find and list all WIFI Networks available using python. Can we print all available wifi connections by using python sockets. If sockets can't do this job then which library can we use to do so?

Answer 1

I think one of the best modules for wifi manipulation in python is the wifi package.

pip install wifi

Simple use case is; (replace "wlan0" with your wireless device id)

from wifi import Cell, Scheme
list(Cell.all('wlan0'))

This will return a list of Cell objects. Each object will have the following attributes:

• ssid
• signal
• quality
• frequency
• bitrates
• encrypted
• channel
• address
• mode

For cells that have encrypted as True, there will also be the following attributes:

• encryption_type

To connenc to an AP;

cell = list(Cell.all('wlan0'))[0]
scheme = Scheme.for_cell('wlan0', 'home', cell, passkey)
scheme.save()
scheme.activate()

scheme = Scheme.find('wlan0', 'home')
scheme.activate()
