This is an anecdote but I used to use a variety of powerline adapters to connect my desktop PC to a switch two floors down in the basement of the house I am living in. The house wiring is pretty modern (done in the mid 90s) but I had quite an unstable connection and mixed results with various brands of powerline adapters. I think if the signal has to jump between two breakers in the power panel then you're just going to have a bad time vs if you are on the same loop. I have used the TP-Links that you had in your pic (or a variation of that model) but I've found that they and all others tend to only last a year before their quality severely degrades. My guess is that extensive usage everyday causes them to endure multiple heat cycles and they just start to degrade in quality of transmission after too many of these cycles. Despite this being solid state equipment, I swear there must be some component in there that degrades with extensive usage because this phenomenon happened with all powerline devices I've owned. Furthermore, even before they start to degrade I would lose signal about once ever 2-3 hrs and it would require unplugging one side of the connection and replugging it in. Over the course of 3 years this also wore out my power outlet(it became much looser) Like I said, I tried various brands/models. This was because I would replace them once a year. The best experience I had was with TP-Link AV2000 (it had the longest time between disconnects and the best bandwidth) Before that I used TP-LINK AV500 which I would say is average quality. It was good for the first year but then started to really degrade. Before this I used Netgear Powerline 500. It was the worst of the bunch, requiring more frequent resets and it too degraded over time as well. I typically find Netgear business class equipment to be great but unfortunately their powerline offerings were a letdown. I dont know if they have improved on this. Powerline is a fascinating technology and I'm thankful it existed as it got me through 3 years going from poor wifi to finally being able to get a ethernet cable going through the wall.
