Is my powerline adapter choking out my internet speed?

I have a powerline adapter hooked up to my PC with the router in the next room over. Sitting in front of my PC, I do a speed test on my phone using wifi and I get just under 300mbps down. I do a speed test on my PC using the powerline adapter and I barely touch 40mbps down. I also have a wifi adapter in the PC connected via PCIE, when I run a speed test using that, I get just over 100mbps down.

The powerline adapter is a TP Link AV1000. Model # TL-PA7010. Probably over 2 years old now. The wifi adapter in my PC is newer than that. Also, I pay for up to 500mbps down.

What might be causing the inconsistency?

Sounds like it. Powerline adapters aren't perfect, they're a workaround type of solution.

If it's just the next room over, I'd just run cat6 cable through the wall. Or just use WiFi.

powerline ethernet can be very finicky, especially if your receptacles at each end are not on the same "leg" in your panel.

A good powerline adapter connection can break 100Mbps.

Just run some ethernet cable if you can. Otherwise, MoCA is a much faster and reliable option if it would work for you.

Only reason I don't use WIFI is because I have ping issues on it.

What equipment are you using? What WiFi spectrum and channel were you using?

I'm one who only recommends wiring but WiFi 6 and newer routers have made WiFi suitable for low latency applications like gaming.

I'm not super well versed when it comes to internet but we use panoramic wifi (Model #: CGM4140COM), due for upgrade in a month.

But here's a screenshot that might help.

Powerline networking is basically a lie, the fact they are allowed to advertise anything close to the speeds on the box is shameful.

Expect pitiful speeds, and complete packet loss if someone turns on a microwave.

I don't really have packet loss issues with it, just extreme reduced speeds

What router? It might be worthwhile to upgrade the Wi-Fi card in your PC if it’s a cheapo.

Yes, it will not operate at same speed as rest of network. If connection is needed in same structure, then would recommend running Cat6 as needed.

I used a powerline adapter to extend connectivity to my outdoor shed, it was fine for most days, including me working remotely from the shed. I ended up upgrading from there to get off powerline adapter.

Go wired when possible, wifi if limited access, powerline as last resort

Yeah, wifi4 is.....not new to say the least.

If you need to go the wifi route, you need a WiFi 6 router and a wifi 6 adapter for your PC. That should allow you to game with limited latency issues.

How difficult would it be to run a cable? Attic/Basement access? Which way to the rafters/floor joists run (parallel or perpendicular)?

I had a wireless bridge setup for ages between two routers. Finally bit the bullet and ran a cable and my network has never been more stable.

I'd only have to navigate around 2 door frames that are catty-cornered if I ran a cable along the outside. Probably 50 or 60 feet. I have a long enough cat5 cable already. Anything wrong with that or is cat6 still better?

As in an exterior wall? That will be more difficult because it will (or at least should) have insulation in it.

I'm having a hard time visualizing how the next room over would require a 50 foot cable. Is there not a wall that divides the rooms that you could just pop through?

I'm talking about running the cable up and down the outside of the door frames like this. The cable for the most part would only be visible to me anyway.


It's just a small house we rent by LSU's campus so I'm not really interested in going through the attic/walls & drilling holes.

Welp I just ran a speed test running the cat5 ethernet cable straight to the modem and was getting about 140mbps down.

Here's the kicker. I ran another speed test on wifi from my phone and hit 450mbps.

Is the cable making that much of a difference or is there something else at play? IDK if MOBOs play any role but mine is not old and is a pretty good one. Supports up to 2.5Gbps

Normally the speed limits via cable are 100mbps and 1gbps, so since you're getting more than 100mbps it should go as fast as your internet service. Might be something screwy with your computer.

Have you tried several different speed tests?

I get 1gig over Wi-Fi but I also bought a really good router and Wi-Fi card for my pc.

I don't know how to troubleshoot it if it's a PC issue. I mean I've got an ASUS prime z490 mobo, I can't imagine that's the issue. If I try another cable and I don't see improved speeds I'll just look into the wifi 6 stuff. I just don't understand how my phone gets better speeds by such a huge margin.
