In some cases it works (new cables and within 1 circiut) but usually its more headache than anything else.
But dont worrys we all did shit and wonder why it didnt work.
Just be glad you were not called to a datacenter and started tracing all fibers just to realize that a single stupid uplink is 1 gbit instead of 40 gbit
Yeah, Powerline is horrendous. It’s not only slow AF and sensitive to the underlying power layout in your house, it also causes massive amounts of electrical noise which can mess with receivers, etc.
At my parents house I reused the coax cable for TV. I got a few Moca adapters and I get about 500Mbit/s and they are reliable. It was easier than running Ethernet cable through the walls and outside the house
I'm going to disagree with you there, it's completely situationally dependent. I tried running a wifi point-to-point link from my house to my detached garage, ran like hot garbage. Replaced the link with powerline, was much more stable and faster.
Right tool for the right job. Well really the right tool is to bury something (preferably fiber) between the buildings, but I'm not made out of money and the power line was already buried!
