I used this for a couple of years. Worked great.
It kind of depends on what fuse your outlets are on and how your place is wired.
It is a gamble, but when it works, it works great!
we’re currently using powerline as a stopgap until we can get around to running cables in the attic for a couple of our security cameras. we get about 300 megabit! not terrible imho
I hear a temporary solution about to become permanent 😄
There is nothing more permanent than a temporary fix. Lol
oh god i hope not. I have an ibm mainframe chassis in the garage i’m converting into a high temperature rack, and that’s going to need fiber xD
I got you
I use it to have connection to my washing machine in the basement, I live in the 2nd floor. It works fine. It's nice to have a notification when the washing is done.
For anyone else that needs it, there's also stuff for co-ax. Some cable guy went nuts putting coaxial cable into just about every room of my new (very old) house. I seriously considered MoCA for a bit, but wifi is working well enough for the moment.

+1 for MoCA, for a while I had to have my server in my room because I didn’t have anywhere else with Ethernet, it got so damn hot in here and it was louuud. But I finally learned about moca, ordered an adapter for it and moved the server to the basement. It has worked perfectly so far. The only issue I’ve had is that one time, it started having like 50% package loss, resetting the adapter fixed it though
To burn down the house? Probably.
For a PoE hack?
POE
EOP
Energy Over Peethernet
Of course it will work. Question is what you expect it to do 😁
"Guys, I hacked a nuclear rector using the secret direct protocol!"
Depends on what job you want to be done. It would be a perfectly fine solution to make a very subtle light in the dark room, for example.
How do the pin outs on the USB line up?
When doing this the old fashioned way, you wire the transmit pins on the RJ-45 to 110v AC HOT and the receive pins to common.
(That's an etherkiller, don't make that, it will fry any networking hardware you connect it to)
Power line networking is a thing so why not?
you need to use a crossover cable to get that to work
yes that's called ethernet-over-powerline
Curious to see what the packets are saying from a packet dump.
My ex did that in college with her ps4, and I won’t lie, I was impressed that the latency was so low for such a shitty apartment
Your ex did what? Plugging a USB C Ethernet adapter into a power supply won't do anything except power the adapter.
It's not like it'll function as a PLC.
I mean I can’t really ask her now can i
Yes, it will give Power Over Ethernet to whatever PoE device you plug it into.
No. That is an Ethernet to USBC so it's trying to get data to the power plug. I don't think it will provide POE
If your goal is to burn your house down, probably.
It shouldn't; the USB wall plug will provide 5 V which powers the dongle, but it'll just be idle since there's no computer communicating with it over USB.
