Hi,
I just bought a Devolo power line set (2 devolo devices). I plugged them directly into wall outlets and connected one with my router and one with my laptop via a RJ45-USB-C adapter, because the laptop hasn’t a built-in RJ45 slot.
TL;DR
The Laptop (using a RJ45-to-USB-C adapter) doesn’t connect via the power line devices to the router. According to the ethernet settings the ethernet cable isn’t plugged.
Power Line Set-Up:
Router ◄───► RJ45 ◄─────► Power Line Adapter
▲
┌───► Power Line ◄──────────┘
▼
Power Line Adapter ◄───► RJ45 ◄───► RJ45-to-USB-C Adapter (Anker)
▲
┌────────────────────────────────────┘
▼
USB-C ◄───────► Laptop
The Problem
After plugging everything in, the devices blinked red, then white. That’s—according to the manufacturer’s manual—the confirmation that the power line devices found themselves and connected securely.
I, then, looked into the network manager, and it said:
I then disabled the Wi-Fi, but it still said, the cable is unplugged.
How do I set up the connection?
