Windows pc calling home (even while asleep)
(lemmy.dbzer0.com)
I have a network-wide pi hole and I noticed that it requested activity.windows.com, a url blocked by my pi hole, even while my pc is suspended. I pinged 10.0.0.217 and it is currently unreachable. So, somehow, windows pc’s turn on networking, phones home, and turns off even while suspended.
Creepy behavior
Go to your NIC's properties and scroll down to disable WAKE ON MAGIC PACKETS.
If you have any device that scans for your MAC (probably your router) it will wake up. Drove me crazy until I figured it out
It's most likely modern standby (S0 standby) and not a WOL packet.
All modern laptops default to this, and the latest don't even give you an option to turn it off.
It was not in my case, the wakes happened when my router or HA controller scanned the network. Changing wake on magic packet (already had wake on lan disabled) remedied it for me.
It probably is that, makes sense. Not sure what devices would be doing it... (Xfinity router?). I even moved to a new house with different devices, router etc and it still did that.
I think it's any device that scans for known devices so I'd imagine most routers
