I just built a gaming computer and bought a wifi adapter to connect to the motherboard to get internet. This computer is upstairs in my room, while the modem and router is downstairs. I noticed that while I was trying to download League of legends that the speed was only 40 kbps. So I was thinking of buying a wifi extender to put up in my room to get a better connection. My question is will this work and what is a good one that is fairly cheap and has a speed of 300 mbps? Thanks in advance.
