Connection speeds on powerline adapters have become unstable recently.
Connection speeds on powerline adapters have become unstable recently.
Thanks, I'll give it a shot once I'm back. Just want to make sure my PC's Ethernet connection is working properly.
Do you have a Cat5 cable? Consider switching to a more recent model, though it’s possible the problem was resolved previously.
They are the cables included with the adapters. If a factory reset doesn’t resolve the issue, that might be my next move. I’ve been researching this problem and it seems 40-50Mbps is typical for PL adapters in homes. Still, my connection hasn’t been reliable lately—especially since audio issues started just last week.
Consider checking the Ethernet controller first; it's possible it's missing, and you can get a replacement for around fifteen dollars.
Believe it or not, that's the only desktop PC (or device) we have in the house with an ethernet port...everything else runs strictly off of wifi. Well, I do have a rpi 3 but I believe the ethernet capability is so severely limited on that device, I doubt it will really tell me anything =(
There are likely devices nearby the same breaker panel generating interference, such as a space heater, which affects the powerline adapter's performance. This makes them less than perfect for use. If you're positioned right above the router and your Wi-Fi is weak, especially in older homes with metal elements like chicken wire, consider the antenna setup. The diagrams illustrate antennas angled slightly outward, possibly for aesthetic reasons, but this changes how signals travel. Surprisingly, placing the main antenna flat and straight from the router backside can significantly boost your signal upstairs.
I think I've tied every possible antenna configuration and this is a new(ish) home that's about 20 years old. If I have no luck with the PL adapters, I'll try your suggestion laying the center antenna flat. The PL adapters have worked flawlessly up until now...not sure what might have changed.
I've worked with powerline adapters in older homes with weak Wi-Fi signals. It looked like they needed proper polarity—whether the left side connected to hot or neutral mattered. One adapter might have been unplugged and reinserted incorrectly. If that doesn’t resolve the issue, try swapping it with another outlet in the same room as your router for testing.
If speed improves then narrow down the problem by checking for interference from devices like microwaves, refrigerators, chargers, or smart bulbs plugged into any of the outlets connected to the two breakers you’re using.
Breakers can also cause interference if they have safety features such as AFCI or GFCI protection. Lastly, consider the quality of power and grounding—some homes might need more than just a line adapter. Powerline adapters help with Wi-Fi but can introduce other complications.
The only method I know for connecting the PL adapters is by plugging them in. I believe polarity isn’t a concern here. On Friday, I tried resetting the adapters and then ran a speed test upstairs—my connection was about 60 Mbps, which isn’t too low. After that, I played Star Trek Bridge Crew VR and noticed my audio problems were fixed. But on Sunday I faced major lag and audio issues again, making it hard to play with friends. My speed test showed around 68 Mbps download. I’m starting to think the problem lies with the game servers rather than my internet connection.
You can also verify your WiFi channels. If your current channel is too crowded, it may lead to problems. The optimal channels to use are 1, 6, and 11 because they don’t overlap.
