I currently swear by Powerline Adapters for anything that doesn’t move.
They work pretty well don’t they? I used one to avoid running cable for an extra access point. It’s hidden in my kitchen cubby. I’m pretty happy with the setup for now and there’s only a tiny bit more lag when connected to that powerline one. I can finally use the color all-in-one in my mother’s office (she only uses it for photocopies). One day though I want every room in the house to be wired except for maybe the bathrooms and laundry room.
