Using Python to implement an example of automatic reconnection after Raspberry Pi WiFi disconnection (with code)

To achieve automatic reconnection when WiFi is disconnected, the principle is to use Python to monitor whether the network is disconnected, and restart the network service if it is disconnected. Next, I will share the implementation code with you. Friends who need it can refer to it

1.Python code autowifi.py, placed in the /home/pi directory:

#!/usr/bin/python
import
os, time
 while
True:
  if
'192' not in os.popen('ifconfig | grep 192').read():
    print
'\n****** wifi is down, restart... ******\n'
    os.system('sudo /etc/init.d/networking restart')
  time.sleep(5*60) #5 minutes

2.Shell script autowifi.sh , also placed in the /home/pi directory:

#!/bin/sh
python /home/pi/autowifi.py &

3. Automatically start the above script when booting: execute the following command in the terminal window

sudo
cp -f /home/pi/autowifi.sh /etc/init.d/
sudo
chmod +x /etc/init.d/autowifi.sh
sudo
chown root:root /etc/init.d/autowifi.sh
sudo
update-rc.d autowifi.sh default

The above is introduced by the editor Python implements automatic reconnection of Raspberry Pi WiFi disconnection. I hope it will be helpful to everyone.
