Hi everyone,

I am trying to activate and deactivate the "usb modem" by Python code, but it does not work, do you know any way to do it?

I tried with "cmd" command line but it did not work :
import os
cmd = 'ifconfig wlan0 down'
os.system(cmd)

I appreciate very your comments

I don't see where this is related to python.

Hi,

I do it for wifi and it works, but it does not work for the usb modem:

-------------------------------
import os, sys
import time

os.system("Ipconfig /release")

time.sleep(3)

os.system("Ipconfig /renew")

------------------------------
Do you know any other way?

Thanks for the feedback

I presume you are using Windows and that the device is configured correctly and works without Python.

The commands are ipconfig /renew <Adapter> and ipconfig /release <Adapter> .

The Adapter option is only available for a device using DHCP. For devices using a static ip address you need to specify the adapter name, which can be found using ipconfig /all . Refer to MS Technet ipconfig.
