Arp table issue

[Pounii25]

Hi, I easily and well configured upsnap with docker and make it works fine, but I have a problem (or at least seems to be that) with the ARP TABLE of my router. Upsnap works fine if I use it some seconds after the pc turned off, then is not working anymore. My router is a shitty huawei which don't give me access to the arp table in any way. So, there is a work arrount for that, maybe sending the magic package in broadcast mode with upsnap? Didn´t find it, and if I force the machine ip to 192.168.8.255 upsnap see it already up and didn't send any package.

Thanks

Edit: ok I had a moment to read the code, which is already using broadcast to deliver magic packets. I think my issue could be related by my hardware, even I can't understand how works just for some seconds after I turned it off.

Edit: was a setting in bios under power management, Erp that should be off, MSI motherboard.
