I have create Job with some WOL task (i used task type "Wake up on Lan" from visualcron and Other Agent WOL), but sometimes the task success and not have error, but do not wake up remote computer.

I do not make changes and the next day run task success and wake up remote computer.

I also have tried using other agent WOL, but similar problems sometimes happens too.

What would I ask, why do something like this could happen, please provide me feedback or recommendation to resolve this matter.

Thanks.

The problem is either in the network or remote computer. I suggest you rule the network out by trying to wake up another computer - and see if that fails sometimes. If so, it may help upgrading the bios on the remote computer.

I have Job with 20 Task WOL, This problem occurs on a remote computer randomly and alternately with the remote computer is not always the same.

I think my network not have problem, Visualcron PC with remote computer connect with same subnet network and the same switch.

Thanks

If you say that you are experiencing the same with the other application I would recommend using another connection method (another switch or cabling).

I do not understand the solution your provide, if the problem on a switch or cable, of course this problem will occur every day and at the same remote pc.

Task WOL while my problem is not every day run with a normal and this problem occurs every day on the different remote pc.

This problem occurs if in one Job there is more than one task WOL, if I create a single job there is only one task WOL, then the problem does not occur. Is this possibly caused by switch or cable, as you say??
I think not...

So my conclusion, Visualcron have problem if in One Job there are more than One task WOL.
I hope VC Support can give me solution for this problem.

Thanks,
