Powerline Adapter Red Light (1 out of 4) 1.5 years in
Recently my power line network adapter failed. I first noticed that the ethernet wire when plugged in would show Unidentified network. I confirmed that the ethernet wire worked properly, and plugged it directly into the router and internet was recovered.
I investigated all four of my powerline network adapters, three of the four had three green lights, but one of them has a red light on the powerline LED.
After resetting the power line adapter and connecting it close to the others, it still continued to have a red light. I even swapped outlets. All the power line adapters were purchased in 2019, at different time points. The one I own has a model number that ends in US and its version is 2.0.
Are there any steps to help diagnose and repair this problem? Or am I left up to purchasing more adapters because this one failed?
