PC keeps disconnecting periodically for 10 seconds through powerline ethernet.
Issue: My pc disconnects irregularly - sometimes every 5 mins in the evening, sometimes every 30 mins - for around 20 seconds. The issue started some weeks ago (haven't been home much). When it disconnects it does not show any sign of error, no yellow triangle on the taskbar internet icon. When this happens, the regular wifi works (I can instantly check a youtube video on my laptop next to me)
Current set up:
A modem with router downstairs and 3 powerline extenders throughout the house. We purchased this a month ago. One is in my bedroom (the furthest one from the router) and I'm using ethernet to connect to my desktop. Modem: Telenet, from Belgium. We can't remove the modems. Router: TPLink Archer C2300 Extenders: TPLink WPA8630 2.0
Already done:
- switched to another extender
- updated windows & drivers
- resetted the modem
I have no idea how to locate the issue. Is it my desktop (self build) or is it the adapters. It is extremely annoying. I did not have this issue with the previous powerline adapters.

Possibly dirty power, spikes and or other electronic interference. Check for grounds, install some surge protection and or UPS power for your setup. May even be appliance starting or running. Hope this helps...
Thanks for the reply. Since the previous powerline adapter did not have this issue, do you think the dirty power issue could still apply? I checked for UPS power cause I don't know it. It's for the power itself, but my pc does not power down, only the ethernet.
I use a cyberpower UPS, it not only maintains a nice range for voltage, but filters RFI & EMI from the power. The terms EMI and RFI are often used interchangeably. EMI is actually any frequency of electrical noise, whereas RFI is a specific subset of electrical noise on the EMI spectrum. There are two types of EMI. Conducted EMI is unwanted high frequencies that ride on the AC wave form. Radiated EMI is similar to an unwanted radio broadcast being emitted from the power lines. There are many pieces of equipment that can generate EMI, variable frequency drives included. In the case of variable frequency drives, the electrical noise produced is primarily contained in the switching edges of the PWM controller. As the technology of drives evolves, switching frequencies increase. These increases also increase the effective edge frequencies produced, thereby increasing the amount of electrical noise. All that said, Ethernet over power is more sensitive than your PC. Perhaps the previous adapter had better "tolerance" thru design than the new one, or something is emitting RFI or EMI that was not before. Loong time user here, and "back in the day" I learned the value of good clean power, so I always use strips with good surge protection and RFI & EMI filters, and my PCs & network equipment, and TV antenna on a good UPS and well grounded. My equipment lasts longer, and darn near error free. Ymmv,
