Need help identifying a wall plug
It was impossible to get a good picture from the outside so here it is unscrewed from the wall, as seen from the inside.
It looks like it could be Ethernet, but much more narrow - my Ethernet cables don't fit. Can't find anything online.
I'm hoping I can use this to pass high-speed Ethernet (directly or with adapters) to replace my slow powerline setup, but it might be just a slow telephone line or something.
