Yesterday there was a major catastrophe with my ISP (my computer ISP and the mobile ISP are different) and we didn't have home internet for over 16 hours. So I decided to modify a script a friend wrote for me which to check for internet connection every 15 minutes and depending on the result to display a message in a dialog window.
But the script keeps showing there's no internet connection even now when there is. I took the command from the internet and I can't seem to make it work. I wanna have this script working for the next time the connection dies, as rare as it may be. The problem is that I do have internet connection now, but the script keeps displaying that there isn't, so obviously I'm missing something or doing something wrong.
The basic idea of the script was to ping a local server with just one packet - far from enough to overload the server and yet more than enough to find out whether there's internet connection and its condition.
On top of that, if I run the script through "Automatically started programs", it displays the dialog window twice at once - you click OK to close the message and it turns out there's the same window under it, so you have to click OK again and I can't see a reason why this is happening. The original script - the one that my friend wrote for me - it doesn't do that. So, if you have any suggestions why the second window, that would be great.
Here's the script I modified:
