I am a Pc gamer and I've always had some wifi speed issues. I recently found out my wifi card only gets up to 150 mbps so when I build my new PC I will get one with 300 mbps. I did a speed test and I only had 5 mbps download speed. How can I make this work faster. By the way the wiring under my house is bad. Will getting a new router help? And can I get a router in my room that connects to the one downstairs? I don't know much about internet.
