If you need basic internet needs and the WiFi is not working due to walls, floors and other things, just buy this and you're done! That works well enough. However, if you're looking for HIGH-SPEED data throughput and need to use any outlet connected to a GFCI-protected line, get Wi-Fi instead - it won't help. Here are some real numbers: I'm paying for a 100Mbps download/20Mbps upload. On my Wi-Fi system with a $400 Orbi mesh router 8ft from the router, my laptop gets 90Mbps download / 20Mbps upload over Wi-Fi. With this device I get 612 Mbps download and 612 Mbps upload at the same air distance but probably more than 25 feet of cable. Why? Because this device does not work well on GFCI sockets. The problem, however, is that my router has to be in the kitchen because there's internet there, and the entire kitchen is GFCI protected, so you won't get electrocuted near running water. Therefore, this device is not suitable for me. Instead I have to use a Wi-Fi repeater. If none of the ends you are connecting to are GFCI protected, buy one as it looks like it will work fine! Also note: it may not work *at all* with surge protectors as they also interfere. Plug directly into an outlet. Powerlinks 2ft apart, both on GFCI outlet: 3035Mbps download, 20Mbps download Wi-Fi 3ft from router: 90Mbps download, 20Mbps download outdoors, through 2 walls, likely 50 ft of cabling): 612 Mbps download / 612 Mbps download / 0 Mbps (no connection) when connected to a Wi-Fi network filter (high-end Orbi router, to a laptop in the same location - across 2 walls) 15 feet): 7090 Mbps download, 20 Mbps upload. As you can see, the GFCI jack kills my PowerLink signal here, so I'll buy a Wi-Fi repeater instead. I sent this product back and left with the repeater. I'm now getting a stable 3070 Mbps download (typically 50 Mbps)/20 Mbps upload at this location when connected to an extender that receives Wi-Fi from the router. It's much better than Powerlink (again because of the GFCI socket in the kitchen which makes Powerlink not work properly). Powerlink from laundry room to living room (probably 100+ feet of wiring): 18Mbps download and 18Mbps upload. - which is impressive because my mesh router had to get it to the laundry room first, so it's actually not bad for that.
