🔒 Wifi to ethernet bridging problemu

[gusty apex]

I used this python script in order to bridge wifi to tehernet but it just crashes in 1 minute
from subprocess import check_call, check_output, Popen, PIPE, run
from sys import argv, exit
from threading import Thread
from time import sleep

def get_ip(interface_name):
return check_output(['ip', '-4', '-br', 'addr', 'show', interface_name]).decode('utf-8').strip().split()[-1]

check_call(['ip', 'addr', 'add', ip, 'dev', ethernet_interface])
check_call(['ip', 'link', 'set', 'dev', ethernet_interface, 'up'])
check_call(['ip', 'link', 'set', wireless_interface, 'promisc', 'on'])
except:
print('pre_start error')
# In case of error, try to clean up
pre_stop(ip, ethernet_interface, wireless_interface)
exit(1)

run(['ip', 'link', 'set', wireless_interface, 'promisc', 'off'], check=False)

                print('process stopped unexpectedly', task)
                exit(1)
