Pros: Easy setup.

Cons: Speed results vary greatly from outlet to outlet. Linksys Powerline Utility crashes on Windows 8 (works on Windows 7).

Overall Review: I have Cox 100Mbps internet. I average 87Mbps on a wired computer. Connected PLEK400s to router and to this same computer. Now I only get 56Mbps (at best). The PLEK400s were on the same power wire (two outlets in the same room, same circuit). Next, moved one PLEK400 to a computer in another room (different electrical wire, different circuit). Now I'm lucky to get 20Mbps. That's a huge drop! I tried upgrading the firmware, but that didn't help.
