UPS within the electrical grid interfering with the power line system
UPS within the electrical grid interfering with the power line system
I understand the title might seem odd, but right now it's hard to have both my Powerline Network and UPS active simultaneously. I've been looking into cases like this without much luck. Could anyone here relate or know of something similar? I've had a TP-Link Powerline AV500 network installed in my home for three years (I've attached a diagram for clarity). My setup includes:
- One modem/router from my ISP
- Ethernet cable linking the Powerline Modem to the AC outlet
- Three Powerline clients spread across different rooms, all plugged into the same AC socket
The typical bandwidth between the clients and the modem is around 270 Mbps. The AV500 specs are average. Recently I built a PC and started using a UPS because my local power fluctuates between 204-226 volts. As soon as I connected the UPS to the outlet, the Powerline network stopped working. The maximum speed on the network is only about 10 Mbps. On the internet side, my ISP modem shows 40 Mbps download, but all Powerline clients report just 1 Mbps max.
I’ve tried troubleshooting the Powerline network without success, but unplugging the UPS always restored everything. I suspect the UPS might be introducing high-frequency interference into the wiring, disrupting the signal. I’m planning to add a surge protector before the UPS to filter out any electrical noise. I’ll let you know once it’s installed and if I find any relevant information. Thanks for your help, even though I haven’t found anything similar yet.
These powerline adapters often fail to perform consistently, making them unreliable. When they don’t work, it usually means there’s no effective solution available.
It looks like this setup is functioning smoothly. The UPS is fully charged, and there are no issues despite multiple devices running simultaneously—like an air conditioner, microwave, freezer, fridge, and a TIG welder.
