And if you can't use MoCa - say, bc the cable installers cut all the other coax cords on the house (true story!) - you can also consider powerline adapters to send Ethernet over your electrical wiring. It's a crapshoot depending on the quality of your wiring but I can usually get at least the same speed as my wifi with it.

Just read up on that, seems very interesting. I don't think it's a great option for my setup since there's only one coax port in the house, but I learned something new today.
