Summary: I bought this to have a better connection between the main desktop and the peripherals connected to the router (and the NAS I am about to buy). I didn't need this for faster Internet access since the WiFi I already had was already fast to use all of the bandwidth supplied by the provider. While I'm not 100% happy with the result (which is positive still), I would probably buy this again for the right price.
Pros: It did increase the bandwidth of my network connection (but not dramatically). Seems pretty stable so far.
Cons: Not truly plug and play with Win 8.1. Had to install a component from the included CD-ROM and ran the utility. Takes some time for the units to find each other on the network. When all is configured, connection speed nowhere near the claimed 500 Mbps limit so there is a tiny bit of misleading advertising here.
Summary: Works as advertised, had no setup problems. Use is very straight forward, just plug them in to outlets and connect Ethernet cables. I plan to get more of these to use as an alternative to wireless.
Summary: I even unplugged these to move some stuff around. Plugged it back in (different outlets too) and it didn't need resyncing. I honestly forgot I had these because they work so well. I was staring at the lights today and it dawned on me what i was looking at so I thought I'd write a review about the experience. I was sceptical that this technology worked as well as everyone said but I'm glad I went for it. Way better than pushing cable through the walls.
Pros: easy to set up. small.
Cons: took a couple tries to sync but it's only once.
Summary: Truly plug and play. Tested it between my computer and Mini PC. I'm able to get around 93 Mbps UDP traffic. TCP traffic is a little less than 80 Mbps. Please realize that the 500 Mbps rating is the PLC speed and not UDP/TCP data rate. From my understanding, the benefit of 500 Mbps PLC speed over the 200 Mbps PLC speed is the ability to recover from a collision faster. It is just an ethernet bridge that has to do Collision Detection and then random wait to transmit again.
Pros: Newegg delivered quickly, as usual. Good Price, if they worked.
Cons: Everything. I bought these because they are supposedly plug & play. My tech knowledge is average, but I'm not a network expert. The lights show good across the board, but the XBox it's connected to cannot access the network (when I go back to the extremely long and unsightly cat5e cable, it works like a charm again). It comes with a utility program, don't know if that helps at ALL as I'm using it to connect to a gaming system. The instructions are completely worthless...
Summary: It is easy to install and setup within minutes, no driver issues almost like plug and play. It is running as fast as wired network, much stabler and easier than wireless network. My leased house has awkward layout with many weak/dead spots for wi-fi signal. My colleague suggested me to try powerline network and surprisingly it is working well to my desktop PC quite away from router.
