Use your cat5e as you can.
Get a Google Mesh setup. https://www.cnet.com/news/get-a-4-terabyte-usb-3-hard-drive-for-72/ down the page notes a deal that I checked out yesterday.
Hi. I moved into a large house that is wired with cat5e throughout all with non terminated ends in the garage. It also has in 4 sets of in-ceiling speakers hooked to a receiver/amp in the garage. I have my Fios modem in the garage so I can have the receiver do airplay via airport express. The problem is the WiFi signal is not great in the house. What are my low cost options to improve the WiFi in the house and still connect to the airport express in the garage for music. Help! I’m not a techie.
