Script to ping and reset connection

[DumbTrollface]

Hey folks,

 

I have the problem that I'm using powerline for a wired connection since my wifi is quite slow. But since my home is pretty old the powerline adapter keeps losing connection roughly every hour.

I do have wifi connected but windows still tries to use the wired connection for a few minutes even though it says that it has no connection over ethernet but that wifi works fine.

So my question is: Is there a way to force windows to use both simultaneously or switch immediately?

 

And if not: I already have a script written that resets my ethernet port (which fixes the problem). Can I continously ping my router and if it loses connection do the reset?

 

So something like
 

while (true) { // infinite loop
	int ping = ping.exe //use ping.exe to check connection
	if (ping == ping_failed) {
		reset_ethernet();
	}
	wait(1000);
}

using cmd

Just unplug the ethernet wire ?

You could use Task Scheduler to run that script as often as you want (every 1 second, 5 seconds, 30 seconds, 5 minutes - whatever).

First of all it's pretty hard to access and secondly I don't really have the time for that. I need my internet for work and can't have any downtime.

 

And if you mean to just continue using wifi: I would go from ~25k down to ~2k down. So that's not really an option

But I only want to do that if the connection is actually down

Do what? Run the script?

 

You write the script to check the connection (eg: ping), and if the ping fails, the script executes an action (eg: reset ethernet adapter).

 

The Task Scheduler continually runs the script, to check the connection.

 

It would only reset the connection IF a ping test failed.

 

With that in mind, you might need to modify the script to make this work.

 

I guess, if your existing script works as-is, you could just put a shortcut to the script into your startup folder, and start it when you turn your computer on.

That's what I want. My question is how I check the connection using ping. Does it return a value?

[DumbTrollface]

Found out that ping does indeed return an exit code and that you can check the exit code of the previous programm by using %errorlevel%.

 

@echo off
ping router
if %errorlevel% NEQ 0 (disable_device
	timeout /nobreak /t 10 //Wait 10 seconds
	enable_device
)

And after some testing it seems to work.

 

EDIT: If someone is curious: I use devcon for disabling and enabling the device
