I noticed in LTT's recent Linus goes into a real girl's bedroom - Intel Extreme Tech Upgrade video Linus got her powerline adapters to use instead of WiFi. I actually have the same issue with my setup being in a basement. I use MoCa adapters to more efficiently get a hardwired internet connection. They are way better than powerline and can travel longer distances through a home without loosing any internet speeds. They only Cons are they are slightly more expensive, require a little more knowledge to set up with a PoE filter. The latency is only marginally more than using straight Ethernet from what I understand, but would love to see it tested and the results shared in a LTT Video as well as an easy guide/explanation on how to use them for the Viewers! I think its is a way better alternative for people in the same situation.
