We have two different apartments, side by side (same floor), with separate electrical panels. For some reason Powerline can transfer Ethernet between the two apartments (with a bit under 60Mbps bandwidth!). Some times the Powerline adapters may need to resync or just stop working, but that happens very rarely (~2 times a year).
Should I be worried that the two apartments are sharing wiring or that their panels are not separating them properly?
