which hardware would be better

[WhatsTheWifiPassword]

Hello all, got a question on hardware for this situation. Currently, I have a modem/router which my family of three are sharing right now. 

 

1 laptop and 2 desktops, which one of the desktops is using Ethernet. 

 

Today when updating software for my parents, i realized that their wifi speeds were abnormally slow,  .4 Mbs down, and 1 MBs up.

on Ethernet, my speeds normally are: 60 mbs down and 5 mbs up 

 

the attached image is the layout of my modem and computers 

Yellow = modem/router

red = laptop on wifi 

green = desktop on wifi 

blue = desktop on Ethernet

black is a wall seperating the living room where the modem is at, and computer area. 

 

 

I am wondering whether i should get a router or a switch in this situation

Is it possible to move the WiFi modem? If not, maybe powerline if you're not gaming.
