My neighbor suspected he had daily Internet connectivity outages always taking place at the same time. I wrote this very simple Python script that pings Google.com at regular intervals and logs the\u00a0ping time and success\/failure. He was able to take this log to his ISP and escalate his tech support case with good evidence of technical problems.<\/p>\n
You can modify the script to ping your router instead of google.com i.e. 192.168.1.1 if you suspect local network problems.<\/p>\n
Usage<\/strong><\/p>\n From command line run .\/pinger.py [seconds] like: .\/pinger.py 120 to ping every two minutes. In Windows, with Python 2.x installed, you can also double click the icon and the script will ping once a minute.<\/p>\n The script will save a .csv log in the same directory. You probably don’t want to ping at very short intervals for prolonged periods of time or it may be construed as a DoS attack by Google.<\/p>\n Force quit the script after you have collected enough information. Otherwise it will loop forever.<\/p>\n My neighbor suspected he had daily Internet connectivity outages always taking place at the same time.
