TP-Link AV2000 Powerline Ethernet Adapter TL-PA9020P KIT - Powerline Network Adapter w/ Passthrough, Noise Filter, 2x2 MIMO, 2 Gigabit Ports, Ethernet Over Power, Plug Pair & Play, Power Saving Mode

I work from home and NEED a fast, stable internet connection. We have 1Gb speed through Xfinity, and while my husband (who works in the basement) has always had solid WiFi, my second-floor office has been an absolute nightmare. Constant drops, unstable speeds, and getting kicked out of Teams calls—it finally hit a breaking point this week when I had multiple disconnects and a full meltdown.We’ve tried Google WiFi pods before, and while they helped, they were still inconsistent. Xfinity came out to check our setup and confirmed that:1. The modem and router were fine.2. The issue was WiFi range to my office.3. My laptop’s network card was bad (great).So now what?! I even tried bribing the Xfinity tech for a magic fix, but no luck. Enter the TP-Link Powerline adapter—I ordered it immediately, praying this would be the solution. And let me tell you… it did NOT disappoint!My Setup:• Router: ASUS RT-AX3000 Ultra-Fast Dual Band Gigabit Wireless Router• Modem: ARRIS (SB8200-RB) - DOCSIS 3.1 32x8 Gigabit Cable Modem• Laptop (No Ethernet Port): Used a USB-to-Ethernet adapterSetup & Performance:Setup was stupid easy—literally took 2 minutes:1. Plug one adapter into a WALL OUTLET near the router.2. Plug the second adapter into a WALL OUTLET in my office.3. Connect via Ethernet. Boom. Done.Now, some important tips:✔️ PLUG THESE INTO A WALL OUTLET. Do NOT use a surge protector or extension cord—if you do, your speed will tank. (Trust me, I tried and got like 2Mbps LOL.)✔️ Speed tests before TP-Link Powerline:• WiFi 2.4GHz: 15 Mbps• WiFi 5GHz: 20 Mbps✔️ Speed test with TP-Link Powerline plugged into an extension cord: 2 Mbps (pathetic)✔️ Speed test with TP-Link Powerline plugged into a wall outlet: 120 Mbps!!! And not just a momentary boost—a consistent, reliable 120 Mbps in my office!If you have a room in your house where WiFi is out of range, slow AF, or just unstable, GET THIS NOW. It will change your life. I wish I had bought this years ago instead of suffering with terrible internet. 5 stars all day!

When new flooring was installed on the upper level of our home, it included underlayment with a reflective Mylar type face. Once installed, the WiFi signal downstairs became unstable and weak. Searching for a solution I came upon this device which, when connected to the router, transmits the internet signal over the house electrical wiring from what I call the base station to the remote stations wherever they are plugged in. Presto, a solid internet connection, both WiFi and ethernet wherever you have an electrical outlet or are within range of one. Works great. I bought this item to have additional 'remote' stations available.

What I needed was a method of getting a good/great signal into a room that has spotty WiFi. Some days it's good, others it drops every few minutes. Although I got less running a cable than my WiFi (unusually good), I do have enough to conduct a Zoom or Skype-type call. In all fairness, the item does suggest that you run them on the same circuit. Most homes have different circuits upstairs and downstairs. So mine is not on the same circuit. Still works well enough for me. I would have liked more from the cable, but I hope it will be more reliable.

I have had notoriously slow internet connectivity at my house. I tested my download speed on Ookla before and after installing. The installation took about five minutes. My download speed before the install was approximately 14 mbps. My download speed after the install was approximately 83 mbps. No more dropped phone calls and choppy video/audio for those Zoom meetings.

(updated review) 2nd day ownership update:These powerline adaptors completely wiped out my TP-Link Archer C9 router. No joke.I've owned the C9 since Sept 2015 (two months shy of three years), and it has been near perfect. Throughout all of this powerlined adaptor testing I haven't touched my C9 one bit (acting as a simple AP). About an hour after plugging the pair of these powerline adaptors in (one a floor below C9, one a floor above it), slowly but surely all my 2.4, then 5.0G devices drop out. My smart plugs stop responding, Alexa's stop responding, my nest looses its connection... I just noticed my freaking nest rebooted a minute ago for no reason. All the while the powerline adaptors chug along while I perform testing throughout the house. After I unplug the powerline adaptors I have to cold cycle the C9 - it will last anywhere from a few hours to a day at best now before doing the same thing, dropping all my devices. During this if I jack into the ethernet port on the back of the C9 (essentially acting as a switch), I can ping it, get an IP address from my other DHCP server, and connect outbound through my gateway, but NO WIFI. SSIDs are being broadcast, but even if I manually assign an IP I cannot seemingly get any packet movement through the router (have not verified with wireshark). The powerline adaptors seem to directly affect the radios, or power supplies (see below) in this router. I've been setting up and debugging home, corporate and industrial networks as an EE for 15 years, so this is not new to me.If I had messed with the C9's cabling, configuration, power cycled the C9, even moved it prior to testing these adaptors, well I would give these the benefit of doubt and say I inadvertently did something to screw it up. But it was working 100% for months up until now (installed after a move) - and going on three years prior. If it's a coincidence, well I'm sorry to make assumtions, but I'm just putting it out there.I load tested my original C9 12V power adaptor at 3amps for 15-20minutes, and it works as expected. Out of curiousity I plugged a powerline adaptor in and scoped the loaded adaptor 12V output: as expected the powerline adaptors are injecting nearly 800mV of high frequency noise *through* the AC adaptor. This noise shows up at the output of the AC adaptor, every 35mS, for about 400uS in duration and yep, directly into the router. This wasn't even transmitting between adaptors, just an apparent preamble and payload, likely broadcasting for other node discovery. Granted this is the case with any powerline adaptor, however this noise, depending on the frequency, could easily throw switching mode regulator out of whack... If not the AC adaptor itself (I didn't note if this was a linear or switching, but I have to assume switching to get 3.3A@12V), then quite easily any downstream electronics (the C9 no exception) will face issues (with any powerline adaptor).After seeing and experiencing this first hand I am absolutely avoiding powerline adaptors. Do yourself a favor and make due with WiFi.(original review) 1st day ownership:My setup is as follows:1st floor: internet and gateway/router, NAS.2nd floor: cat5 from 1st floor to Archer C9 acting as access point.3rd floor: needed hardwired connection for various office devices (printers, etc).Speed results:1)with units biggybacked, (one plugged into the other):-TPlinkUtil showed 997Mbps (124MBps). File transfer from NAS 328Mbps (41MBps)-wifi NAS transfer 376Mbps (47MBps)2)with one unit on 1st floor, the other on 2nd floor at three different sockets (kitchen/dining/living):-TplinkUtil showed 150-229Mbps (19-29MBps). File transfer from NAS 120-146Mbps (15-17MBps)-wifi NAS transfer (5G AC) 528Mbps (66MBps)3)with one unit on 1st floor, the other on 3rd floor at various sockets (office, bedroom):-TplinkUtil showed 34-79Mbps (4-10MBps). File transfer from NAS up to 96Mbps (12MBps)-wifi NAS transfer 184Mbps (23MBps).Clearly there is very little benefit over a wifi adaptor for using these adaptors, in my setup anyway. A cheap no-name 300N USB adaptor was able to get me the same speeds.Lastly, if browsing the web and doing speedtest tests are all you need, maybe you'll be fine.One note: realize that in most US households the 220 service is broken into two separate 120 "legs". Where the circuit breaker is physically installed inside the electrical panel dictates which leg it's on (often it alternates between one leg and the other when viewing the breakers vertically). To get full performance out of a (any) powerline adapter you *must* be on the same leg as the other adapter(s). Yes they share a neutral and ground but to get the benefit of the "MIMO" you need the other leg also.
