Powerline adapters (last resort)
Powerline adapters use your home’s electrical wiring to carry network traffic. They can work — but performance is highly variable. For dead zones, powerline is usually a last resort behind Ethernet and MoCA.
Quick take
If you have coax, buy MoCA. If you can run a cable, run Ethernet. If you have neither, then powerline is worth trying.
When powerline is worth trying
- You can’t run Ethernet and you have no usable coax jacks
- You only need one room stable (office/bedroom)
- You can plug directly into wall outlets (not power strips)
Common failure modes
- Old wiring / noisy circuits
- Adapters on different electrical phases (performance tanks)
- GFCI/AFCI outlets or surge protectors blocking signal
