Powerline ethernet is a decent alternative to ethernet cables or wireless, but there definitely are significant caveats:

* It generates tons of electrical noise, which can wreak havoc on electronics particularly radios.

* The actual connection speed varies greatly by the condition of the copper wiring and generally isn't that great.

* Depending on how the copper wiring is laid out, you might not get a connection between two points.

* Security can be an issue if you don't configure your powerline adapters properly.
