Used this for a couple years since the wireless sginal was weak where my room was, and using a 500 MB/s device was decent. Though a couple times a week it would randomly drop out for several minutes which required unplugging/plugging back in the device. Not sure if it was due to the wiring of the house or what; it seems like it'd be a hard problem to troubleshoot. The Powerline standard has only gotten better though with time. As little as ~7 years ago there were only 50 MB/s devices. They now have gigabit-level ones.
