Can be unreliable though based on what else is on the circuit. Had a portable ac that completely took my power line ethernet connection out whenever it ran.

Based on my research, you get the speed of 2.4 ghz wireless (which while it works, it could be better) with the inconvenience of having to use a cable. Performance also depends on wire insulation, which often isn't built for running PLC. However, you can't beat the "plug-and-play" of wired there, which might be attractive.

I'd recommend getting a mesh router setup, gives you 5ghz wireless over the whole house (assuming proper setup), and some mesh points support wired output (effectively having a wireless bridge)
