The Good Practical for home networking; good if you can't use Wi-Fi or Ethernet.
The Bad Not as good as wired Ethernet; can sometimes crash.
The Bottom Line If wireless networking just isn't quick enough for you, then you'll appreciate the speed boost afforded by powerline networking. The Solwise Piggy6 is a great product, providing surge protection for your electrical equipment, while giving you three ports to network various components together
Although powerline networking -- sending your network signals via your home electrical wiring -- isn't a perfect solution, it meets a need in homes that either don't or can't use Wi-Fi. It might also appeal to those who don't want to rip up their carpets and bulldoze their walls to run Cat5 networking cables everywhere.
The ridiculously named Solwise NET-PLA-AV-3E-PIGGY6
Powerline networking can be really useful for moving large amounts of data around your network at fairly respectable speeds. The suggestion that products like the Piggy6 can manage 200Mbps is slightly spurious, but such products still manage to cope quite comfortably with video of up to 720p resolution.
