Understanding routers

I share a 100 mbps plan with three other people. In the evenings when we are all home, the wifi sucks. Was thinking it could just be bandwidth problem but since we have the largest plan we have to find another solution. As a test, I plugged my ethernet into laptop and router, DL speed was 77 then on wifi right after that it was 31. I have a simple cisco router. Would buying a better router help. Or should a range extender be the next step?
