My wifi connection was slow and dropped out a lot in the garage, so I put in a Google WiFi setup that helped immensely. I was seeing connection speeds ranging from 19Mbps to 120Mbps before, but am now getting a consistent 250Mbps+. YMMV with everyone's unique layout and there are plenty of other options to do the same, but this worked well for me: https://amzn.to/2ueP9Iq
